libgcrypt: updated to 1.8.2

Noteworthy changes in version 1.8.2:

 * Bug fixes:
   - Do not use /dev/srandom on OpenBSD.
   - Fix test suite failure on systems with large pages.
   - Fix test suite to not use mmap on Windows.
   - Fix fatal out of secure memory status in the s-expression parser
     on heavy loaded systems.

 * Other:
   - Backport the auto expand secmem feature from master for use by
     the forthcoming GnuPG 2.2.4.

Log message:
version 1.8.1:

Bug fixes:
   - Mitigate a local side-channel attack on Curve25519 dubbed "May
     the Fourth be With You".  [CVE-2017-0379] [also in 1.7.9]
   - Add more extra bytes to the pool after reading a seed file.
   - Add the OID SHA384WithECDSA from RFC-7427 to SHA-384.
   - Fix build problems with the Jitter RNG
   - Fix assembler code build problems on Rasbian (ARMv8/AArch32-CE).

Log message:
version 1.8.0:

 * New interfaces:
   - New cipher mode XTS
   - New hash function Blake-2
   - New function gcry_mpi_point_copy.
   - New function gcry_get_config.
   - GCRYCTL_REINIT_SYSCALL_CLAMP allows to init nPth after Libgcrypt.
   - New gobal configuration file /etc/gcrypt/random.conf.

 * Extended interfaces:
   - GCRYCTL_PRINT_CONFIG does now also print build information for
     libgpg-error and the used compiler version.
   - GCRY_CIPHER_MODE_CFB8 is now supported.
   - Add Stribog OIDs.

 * Performance:
   - A jitter based entropy collector is now used in addition to the
     other entropy collectors.
   - Optimized gcry_md_hash_buffers for SHA-256 and SHA-512.
   - More ARMv8/AArch32 improvements for AES, GCM, SHA-256, and SHA-1.
   - Add ARMv8/AArch32 assembly implementation for Twofish and
     Camellia.
   - Add bulk processing implementation for ARMv8/AArch32.
   - Improve the DRBG performance and sync the code with the Linux
     version.

 * Internal changes:
   - Libgpg-error 1.25 is now required.  This avoids stalling of nPth
     threads due to contention on internal Libgcrypt locks (e.g. the
     random pool lock).
   - The system call clamp of libgpg-error is now used to wrap the
     blocking read of /dev/random.  This allows other nPth threads to
     run while Libgcrypt is gathering entropy.
   - When secure memory is requested by the MPI functions or by
     gcry_xmalloc_secure, they do not anymore lead to a fatal error if
     the secure memory pool is used up.  Instead new pools are
     allocated as needed.  These new pools are not protected against
     being swapped out (mlock can't be used).  However, these days
     this is considered a minor issue and can easily be mitigated by
     using encrypted swap space.

 * Bug fixes:
   - Fix AES CTR self-check detected failure in the SSSE3 based
     implementation.
   - Remove gratuitous select before the getrandom syscall.
   - Fix regression in mlock detection.
   - Fix GOST 28147 CryptoPro-B S-box.
   - Fix error code handling of mlock calls.
   - Fix possible timing attack on EdDSA session key.
   - Fix long standing bug in secure memory implementation which could
     lead to a segv on free.
   - Mitigate a flush+reload side-channel attack on RSA secret keys
     dubbed "Sliding right into disaster".
