Update to 3.2.7:

* Version 3.2.7 (released 2013-11-23)

** libgnutls: gnutls_cipher_get_iv_size() now returns the correct IV size in
GCM ciphers (previously it returned the implicit IV used in TLS).

** libgnutls: gnutls_certificate_set_x509_key_file() et al when provided
with a PKCS #11 URL pointing to a certificate, will attempt to load the whole
chain.

** libgnutls: When traversing PKCS #11 tokens looking for an object, avoid
looking in unrelated to the object tokens.

** libgnutls: Added an experimental %DUMBFW option in priority strings. This
avoids a black hole behavior in some firewalls by sending a large client hello.
See http://www.ietf.org/mail-archive/web/tls/current/msg10423.html

** libgnutls: The GNUTLS_DEBUG_LEVEL variable if set to a log level number
will force output of debug messages to stderr.

** libgnutls: Fixed the setting of the ciphersuite when gnutls_premaster_set()
is used with another protocol than the GNUTLS_DTLS0_9 protocol.

** libgnutls: gnutls_x509_crt_set_expiration_time() will set the no well defined
expiration date when (time_t)-1 is specified as date.

** libgnutls: Session tickets are encrypted using AES-GCM.

** libgnutls: Corrected issue in record decompression. Issue pinpointed
by Frank Zschockel.

** libgnutls: Forbid all compression methods in DTLS.

will set to the no well defined expiration date (RFC5280), and no longer
chokes on integer overflows. Suggested by Stefan Buehler.

** certtool: Added new template options: 'activation_date', and
'expiration_date'.

** tools: The environment variable GNUTLS_PIN can be used to read any PIN
requested from tokens.

** tools: The installed version of libopts is used if the autogen tool is
present.

* Version 3.1.7 (released 2013-02-04)

** certtool: Added option "dn" which allows to directly set the DN
in a template from an RFC4514 string.

** danetool: Added options: --dlv and --insecure. Suggested by Paul Wouters.

** libgnutls-xssl: Added a new library to simplify GnuTLS usage.

it is now explicitly done on every session deinit.

** libgnutls: Simplified the DTLS sliding window implementation.

** libgnutls: The minimum DH bits accepted by a client are now set
by the specified priority string. The current values correspond to the
previous defaults (727 bits), except for the SECURE128 and SECURE192
strings which increase the minimum to 1248 and 1776 respectively.

** libgnutls: Added the gnutls_record_cork() and uncork API to enable
buffering in sending application data.

** libgnutls: Removed default random padding, and added a length-hiding interface
instead.  Both the server and the client must support this extension. Whether
length-hiding can be used on a given session can be checked using
gnutls_record_can_use_length_hiding(). Contributed by Alfredo Pironti.

** libgnutls: Added the experimental %NEW_PADDING priority string. It enables
a new padding mechanism in TLS allowing arbitrary padding in TLS records
in all ciphersuites, which makes length-hiding more efficient and solves
the issues with timing attacks on CBC ciphersuites.

** libgnutls: Corrected gnutls_cipher_decrypt2() when used with AEAD
ciphers (i.e., AES-GCM). Reported by William McGovern.

--load-privkey or --load-request to print the corresponding public keys.

** certtool: It is able to set certificate policies via a template.

** certtool: Added --hex-numbers option which prints big numbers in
an easier to parse format.

** p11tool: After key generation, outputs the public key (useful in
tokens that do not store the public key).

** danetool: It is being built even without libgnutls-dane (the
--check functionality is disabled though).

* Version 3.1.2 (released 2012-09-26)

** libgnutls: Fixed bug in gnutls_x509_trust_list_add_system_trust()
and gnutls_x509_trust_list_add_trust_mem() that prevented the loading
of certificates in the windows platform.

** libgnutls: Corrected bug in OpenPGP subpacket encoding.

** libgnutls: Added support for DTLS/TLS heartbeats by Olga Smolenchuk.
(the work was done during Google Summer of Code).

** libgnutls: Added X.509 certificate verification flag
GNUTLS_VERIFY_ALLOW_UNSORTED_CHAIN. This flag allows the verification
of unsorted certificate chains and is enabled by default for
TLS certificate verification (if gnutls_certificate_set_verify_flags()
does not override it).

** libgnutls: Prints warning on certificates that contain keys of
an insecure level. If the %COMPAT priority flag is not specified
the TLS connection fails.

** libgnutls: Correctly restore gnutls_record_recv() in DTLS mode
if interrupted during the retrasmition of handshake data.

** libgnutls: Better mingw32 support (patch by LRN).

** libgnutls: The %COMPAT keyword, if specified, will tolerate
key usage violation errors (they are far too common to ignore).

** libgnutls: Added GNUTLS_STATELESS_COMPRESSION flag to gnutls_init(),
which provides a tool to counter compression-related attacks where
parts of the data are controlled by the attacker _and_ are placed in
separate records (use with care - do not use compression if not sure).

** libgnutls: Depends on libtasn1 2.14 or later.

** certtool: Prints the number of bits of the public key algorithm
parameter in a private key.

** API and ABI modifications:

* Version 3.1.1 (released 2012-09-02)

** gnutls-serv: Listens on IPv6. Patch by Bernhard R. Link.

** certtool: Changes in password handling of certtool.
Ask password when required and only if the '--password' option is not
given. If the '--password' option is given during key generation then
assume the PKCS #8 file format, instead of ignoring the password.

** tpmtool: No longer asks for key password in registered keys.

** libgnutls: Elliptic curve code was optimized by Ilya Tumaykin.
wmNAF is now used for point multiplication and other optimizations.
(the major part of the work was done during Google Summer of Code).

** libgnutls: The default pull_timeout_function only uses select
instead of a combination of select() and recv() to prevent issues
when used in stream sockets in some systems.

** libgnutls: Be tolerant in ECDSA signature violations (e.g. using
SHA256 with a SECP384 curve instead of SHA-384), to interoperate with
openssl.

** libgnutls: Fixed DSA and ECDSA signature generation in smart
cards. Thanks to Andreas Schwier from cardcontact.de for providing
me with ECDSA capable smart cards.

** API and ABI modifications:
gnutls_sign_algorithm_get: Added
gnutls_sign_get_hash_algorithm: Added
gnutls_sign_get_pk_algorithm: Added

* Version 3.1.0 (released 2012-08-15)

** libgnutls: Added direct support for TPM as a cryptographic module
in gnutls/tpm.h. TPM keys can be used in functions accepting files
using URLs of the following types:
  tpmkey:file=/path/to/file
  tpmkey:uuid=7f468c16-cb7f-11e1-824d-b3a4f4b20343;storage=user

** libgnutls: Priority string level keywords can be combined.
For example the string "SECURE256:+SUITEB128" is now allowed.

** libgnutls: requires libnettle 2.5.

** libgnutls: Use the PKCS #1 1.5 encoding provided by nettle (2.5)
for encryption and signatures.

** libgnutls: Added GNUTLS_CERT_SIGNATURE_FAILURE to differentiate between
generic errors and signature verification errors in the verification
functions.

** libgnutls: Added gnutls_pkcs12_simple_parse() as a helper function
to simplify parsing in most PKCS #12 use cases.

** libgnutls: gnutls_certificate_set_x509_simple_pkcs12_file() adds
the whole certificate chain (if any) to the credentials structure, instead
of only the end-user certificate.

** libgnutls: Key import functions such as gnutls_pkcs12_simple_parse()
and gnutls_x509_privkey_import_pkcs8(), return consistently
GNUTLS_E_DECRYPTION_FAILED if the input structure is encrypted but no
password was provided.

** libgnutls: Added gnutls_handshake_set_timeout() a function that
allows to set the maximum time spent in a handshake.

** libgnutlsxx: Added session::set_transport_vec_push_function. Patch
by Alexandre Bique.

** tpmtool: Added. It is a tool to generate private keys in the
TPM.

** gnutls-cli: --benchmark-tls was split to --benchmark-tls-kx
and --benchmark-tls-ciphers

** certtool: generated PKCS #12 structures may hold more than one
private key. Patch by Lucas Fisher.

** certtool: Added option --null-password to generate/decrypt keys
that use a NULL password (in schemas that distinguish between NULL
an empty passwords).

** minitasn1: Upgraded to libtasn1 version 2.13.
