libressl: Leave pkgsrc to handle security features.

Log message:
Fix indentation in buildlink3.mk files.

The actual fix as been done by "pkglint -F */*/buildlink3.mk", and was
reviewed manually.

There are some .include lines that still are indented with zero spaces
although the surrounding .if is indented. This is existing practice.

Log message:
libressl: update to 2.5.4

We have released LibreSSL 2.5.4, which will be arriving in the
LibreSSL directory of your local OpenBSD mirror soon. It includes the following
changes:

  * Reverted a previous change that forced consistency between return
    value and error code when specifing a certificate verification
    callback, since this breaks the documented API. When a user supplied
    callback always returns 1, and later code checks the error code to
    potentially abort post verification, this will result in incorrect
    successul certificate verification.

  * Switched Linux getrandom() usage to non-blocking mode, continuing to
    use fallback mechanims if unsuccessful. This works around a design
    flaw in Linux getrandom(2) where early boot usage in a library makes
    it impossible to recover if getrandom(2) is not yet initialized.

  * Fixed a bug caused by the return value being set early to signal
    successful DTLS cookie validation. This can mask a later failure and
    result in a positive return value being returned from
    ssl3_get_client_hello(), when it should return a negative value to
    propagate the error.

  * Fixed a build error on non-x86/x86_64 systems running Solaris.

We have released LibreSSL 2.5.3, based on OpenBSD 6.1, which will be the new
stable release series. LibreSSL 2.3.x support has also ended. LibreSSL 2.5.3
contains the following changes from the previous stable release.

 * libtls now supports ALPN and SNI

 * libtls adds a new callback interface for integrating custom IO functions.
    Thanks to Tobias Pape.

 * libtls now handles 4 cipher suite groups:
    "secure" (TLSv1.2+AEAD+PFS)
    "compat" (HIGH:!aNULL)
    "legacy" (HIGH:MEDIUM:!aNULL)
    "insecure" (ALL:!aNULL:!eNULL)
   This allows for flexibility and finer grained control, rather than having
   two extremes (an issue raised by Marko Kreen some time ago).

 * Tightened error handling for tls_config_set_ciphers().

 * libtls now always loads CA, key and certificate files at the time the
   configuration function is called. This simplifies code and results in a single
   memory based code path being used to provide data to libssl.

 * Added support for OCSP intermediate certificates.

 * Added functions used by stunnel and exim from BoringSSL - this brings in
   X509_check_host, X509_check_email, X509_check_ip, and X509_check_ip_asc.

 * Added initial support for iOS, thanks to Jacob Berkman.

 * Improved behavior of arc4random on Windows when using memory leak analysis
   software.

 * Correctly handle an EOF that occurs prior to the TLS handshake completing.
    Reported by Vasily Kolobkov, based on a diff from Marko Kreen.

 * Limit the support of the "backward compatible" ssl2 handshake to only be
   used if TLS 1.0 is enabled.

 * Fix incorrect results in certain cases on 64-bit systems when BN_mod_word()
   can return incorrect results. BN_mod_word() now can return an error condition.
   Thanks to Brian Smith.

 * Added constant-time updates to address CVE-2016-0702

 * Fixed undefined behavior in BN_GF2m_mod_arr()

 * Removed unused Cryptographic Message Support (CMS)

 * More conversions of long long idioms to time_t

 * Improved compatibility by avoiding printing NULL strings with printf.

 * Reverted change that cleans up the EVP cipher context in EVP_EncryptFinal()
   and EVP_DecryptFinal(). Some software relies on the previous behaviour.

 * Avoid unbounded memory growth in libssl, which can be triggered by a TLS
   client repeatedly renegotiating and sending OCSP Status Request TLS extensions.

 * Avoid falling back to a weak digest for (EC)DH when using SNI with libssl.

 * X509_cmp_time() now passes a malformed GeneralizedTime field as an error.
   Reported by Theofilos Petsios.

 * Detect zero-length encrypted session data early, instead of when malloc(0)
   fails or the HMAC check fails. Noted independently by jsing@ and Kurt Cancemi.

 * Check for and handle failure of HMAC_{Update,Final} or EVP_DecryptUpdate().

 * Massive update and normalization of manpages, conversion to mandoc format.
   Many pages were rewritten for clarity and accuracy. Portable doc links are
   up-to-date with a new conversion tool.

 * Curve25519 Key Exchange support.

 * Support for alternate chains for certificate verification.

 * Code cleanups, CBB conversions, further unification of DTLS/SSL handshake
   code, further ASN1 macro expansion and removal.

 * Private symbols are now hidden in libssl and libcrypto.

 * Friendly certificate verification error messages in libtls, peer
   verification is now always enabled.

 * Added OCSP stapling support to libtls and nc.

 * Added ocspcheck utility to validate a certificate against its OCSP responder
   and save the reply for stapling

 * Enhanced regression tests and error handling for libtls.

 * Added explicit constant and non-constant time BN functions, defaulting to
   constant time wherever possible.

 * Moved many leaked implementation details in public structs behind opaque
   pointers.

 * Added ticket support to libtls.

 * Added support for setting the supported EC curves via
   SSL{_CTX}_set1_groups{_list}() - also provide defines for the previous
   SSL{_CTX}_set1_curves{_list} names. This also changes the default list of
   curves to be X25519, P-256 and P-384. All other curves must be manually
   enabled.

 * Added -groups option to openssl(1) s_client for specifying the curves to be
   used in a colon-separated list.

 * Merged client/server version negotiation code paths into one, reducing much
   duplicate code.

 * Removed error function codes from libssl and libcrypto.

 * Fixed an issue where a truncated packet could crash via an OOB read.

 * Added SSL_OP_NO_CLIENT_RENEGOTIATION option that disallows client-initiated
   renegotiation. This is the default for libtls servers.

 * Avoid a side-channel cache-timing attack that can leak the ECDSA private
   keys when signing. This is due to BN_mod_inverse() being used without the
   constant time flag being set. Reported by Cesar Pereida Garcia and Billy
   Brumley (Tampere University of Technology). The fix was developed by Cesar
   Pereida Garcia.

 * iOS and MacOS compatibility updates from Simone Basso and Jacob Berkman.

 * Added the recallocarray(3) memory allocation function, and converted various
   places in the library to use it, such as CBB and BUF_MEM_grow. recallocarray(3)
   is similar to reallocarray. Newly allocated memory is cleared similar to
   calloc(3). Memory that becomes unallocated while shrinking or moving existing
   allocations is explicitly discarded by unmapping or clearing to 0.

 * Added new root CAs from SECOM Trust Systems / Security Communication of Japan.

 * Added EVP interface for MD5+SHA1 hashes.

 * Fixed DTLS client failures when the server sends a certificate request.

 * Correct handling of padding when upgrading an SSLv2 challenge into an
   SSLv3/TLS connection.

 * Allow protocols and ciphers to be set on a TLS config object in libtls.

 * Improved nc(1) TLS handshake CPU usage and server-side error reporting.

 * Add a constant time version of BN_gcd and use it default for BN_gcd to avoid
   the possibility of sidechannel timing attacks against RSA private key
   generation - Thanks to Alejandro Cabrera

We have released LibreSSL 2.5.2, which will be arriving in the
LibreSSL directory of your local OpenBSD mirror soon. It includes the following

	  RFC6960. Also added fixes for OCSP to work with intermediate
	  certificates provided in responses.

	* Improved behavior of arc4random on Windows to not appear to leak
	  memory in debug tools, reduced privileges of allocated memory.

	* Reworked error handling in libtls so that configuration errors are
	  visible.

	* Deprecated internal use of EVP_[Cipher|Encrypt|Decrypt]_Final.

	* Manpage fixes and updates

	* cert.pem has been reorganized and synced with Mozilla's certificate store

2.3.2 - Compatibility and Reliability fixes

	* Changed format of LIBRESSL_VERSION_NUMBER to match that of
	  OPENSSL_VERSION_NUMBER, see:
	  https://wiki.openssl.org/index.php/Manual:OPENSSL_VERSION_NUMBER(3)

	* Added EVP_aead_chacha20_poly1305_ietf() which matches the AEAD
	  construction introduced in RFC 7539, which is different than that
	  already used in TLS with EVP_aead_chacha20_poly1305()

	* Avoid a potential undefined C99+ behavior due to shift overflow in
	  AES_decrypt, reported by Pascal Cuoq <cuoq at trust-in-soft.com>

	* More man pages converted from pod to mdoc format

	* Added COMODO RSA Certification Authority and QuoVadis
	  root certificates to cert.pem

	* Removed Remove "C=US, O=VeriSign, Inc., OU=Class 3 Public Primary \ 
Certification
	  Authority" (serial 3c:91:31:cb:1f:f6:d0:1b:0e:9a:b8:d0:44:bf:12:be) root
	  certificate from cert.pem

	* Added support for building nc(1) on Solaris

	* Fixed GCC 5.x+ preprocessor checks, reported by Ruslan Babayev

	* Improved console handling with openssl(1) on Windows

	* Ensure the network stack is enabled on Windows when running
	  tls_init()

	* Fixed incorrect TLS certificate loading by nc(1)

	* Added support for Solaris 11.3's getentropy(2) system call

	* Enabled support for using NetBSD 7.0's arc4random(3) implementation

	* Deprecated the SSL_OP_SINGLE_DH_USE flag by disabling its effect

	                   validation.
	 - CVE-2015-3195 - Memory leak in PKCS7 - not reachable from TLS/SSL

	* The following OpenSSL CVEs did not apply to LibreSSL
	 - CVE-2015-3193 - Carry propagating bug in the x86_64 Montgomery
	                   squaring procedure.
	 - CVE-2015-3196 - Double free race condition of the identify hint
	                   data.

	 See https://marc.info/?l=openbsd-announce&m=144925068504102

2.3.1 - ASN.1 and time handling cleanups

	* ASN.1 cleanups and RFC5280 compliance fixes.

	* Time representations switched from 'unsigned long' to 'time_t'. LibreSSL
	  now checks if the host OS supports 64-bit time_t.

	* Fixed a leak in SSL_new in the error path.

	* Support always extracting the peer cipher and version with libtls.

	* Added ability to check certificate validity times with libtls,
	  tls_peer_cert_notbefore and tls_peer_cert_notafter.

	* Changed tls_connect_servername to use the first address that resolves with
	  getaddrinfo().

	* Remove broken conditional EVP_CHECK_DES_KEY code (non-functional since
	  initial commit in 2004).

	* Fixed a memory leak and out-of-bounds access in OBJ_obj2txt, reported
	  by Qualys Security.

	* Fixed an up-to 7 byte overflow in RC4 when len is not a multiple of
	  sizeof(RC4_CHUNK), reported by Pascal Cuoq <cuoq at trust-in-soft.com>.

	* Reject too small bits value in BN_generate_prime_ex(), so that it does
	  not risk becoming negative in probable_prime_dh_safe(), reported by
		Franck Denis.

	* Enable nc(1) builds on more platforms.

2.3.0 - SSLv3 removed, libtls API changes, portability improvements

	* SSLv3 is now permanently removed from the tree.

	* The libtls API is changed from the 2.2.x series.

	  The read/write functions work correctly with external event
	  libraries.  See the tls_init man page for examples of using libtls
	  correctly in asynchronous mode.

	  Client-side verification is now supported, with the client supplying
	  the certificate to the server.

	  Also, when using tls_connect_fds, tls_connect_socket or
	  tls_accept_fds, libtls no longer implicitly closes the passed in
	  sockets. The caller is responsible for closing them in this case.

	* When loading a DSA key from an raw (without DH parameters) ASN.1
	  serialization, perform some consistency checks on its `p' and `q'
	  values, and return an error if the checks failed.

	  Thanks for Georgi Guninski (guninski at guninski dot com) for
	  mentioning the possibility of a weak (non prime) q value and
	  providing a test case.

	  See
	  https://cpunks.org/pipermail/cypherpunks/2015-September/009007.html
	  for a longer discussion.

	* Fixed a bug in ECDH_compute_key that can lead to silent truncation
	  of the result key without error. A coding error could cause software
	  to use much shorter keys than intended.

	* Removed support for DTLS_BAD_VER. Pre-DTLSv1 implementations are no
	  longer supported.

	* The engine command and parameters are removed from the openssl(1).
	  Previous releases removed dynamic and builtin engine support
	  already.

	* SHA-0 is removed, which was withdrawn shortly after publication 20
	  years ago.

	* Added Certplus CA root certificate to the default cert.pem file.

	* New interface OPENSSL_cpu_caps is provided that does not allow
	  software to inadvertently modify cpu capability flags.
	  OPENSSL_ia32cap and OPENSSL_ia32cap_loc are removed.

	* The out_len argument of AEAD changed from ssize_t to size_t.

	* Deduplicated DTLS code, sharing bugfixes and improvements with
	  TLS.

	* Converted 'nc' to use libtls for client and server operations; it is
	  included in the libressl-portable distribution as an example of how
	  to use the library.
