Log Message:
gnutls: update to 3.8.0.

* Version 3.8.0 (unreleased 2023-02-09)

** libgnutls: Fix a Bleichenbacher oracle in the TLS RSA key exchange.
   Reported by Hubert Kario (#1050). Fix developed by Alexander Sosedkin.
   [GNUTLS-SA-2020-07-14, CVSS: medium] [CVE-2023-0361]

** libgnutls: C++ library is now header only. All definitions from
   gnutlsxx.c have been moved into gnutlsxx.h. Users of the C++
   interface have two options:
   1. include gnutlsxx.h in their application and link against
      the C library. (default)
   2. include gnutlsxx.h in their application, compile with
      GNUTLS_GNUTLSXX_NO_HEADERONLY macro defined and link
      against the C++ library.

** libgnutls: GNUTLS_NO_STATUS_REQUEST flag and %NO_STATUS_REQUEST
   priority modifier have been added to allow disabling of the
   status_request TLS extension in the client side.

** libgnutls: TLS heartbeat is disabled by default.
   The heartbeat extension in TLS (RFC 6520) is not widely used given
   other implementations dropped support for it. To enable back
   support for it, supply --enable-heartbeat-support to configure
   script.

** libgnutls: SRP authentication is now disabled by default.
   It is disabled because the SRP authentication in TLS is not up to
   date with the latest TLS standards and its ciphersuites are based
   on the CBC mode and SHA-1.  To enable it back, supply
   --enable-srp-authentication option to configure script.

** libgnutls: All code has been indented using "indent -ppi1 -linux".
   CI/CD has been adjusted to catch regressions.  This is implemented
   through devel/indent-gnutls, devel/indent-maybe and .gitlab-ci.yml’s
   commit-check.  You may run devel/indent-gnutls to fix any
   indentation issues if you make code modifications.

** guile: Guile-bindings removed.
   They have been extracted into a separate project to reduce complexity
   and to simplify maintenance, see <https://gitlab.com/gnutls/guile/>.

** minitasn1: Upgraded to libtasn1 version 4.19.

** API and ABI modifications:
GNUTLS_NO_STATUS_REQUEST: New flag
GNUTLS_SRTP_AEAD_AES_128_GCM: New gnutls_srtp_profile_t enum member
GNUTLS_SRTP_AEAD_AES_256_GCM: New gnutls_srtp_profile_t enum member

* Version 3.7.8 (released 2022-09-27)

** libgnutls: In FIPS140 mode, RSA signature verification is an approved
   operation if the key has modulus with known sizes (1024, 1280,
   1536, and 1792 bits), in addition to any modulus sizes larger than
   2048 bits, according to SP800-131A rev2.

** libgnutls: gnutls_session_channel_binding performs additional checks when
   GNUTLS_CB_TLS_EXPORTER is requested. According to RFC9622 4.2, the
   "tls-exporter" channel binding is only usable when the handshake is
   bound to a unique master secret (i.e., either TLS 1.3 or extended
   master secret extension is negotiated). Otherwise the function now
   returns error.

** libgnutls: usage of the following functions, which are designed to
   loosen restrictions imposed by allowlisting mode of configuration,
   has been additionally restricted. Invoking them is now only allowed
   if system-wide TLS priority string has not been initialized yet:
gnutls_digest_set_secure
gnutls_sign_set_secure
gnutls_sign_set_secure_for_certs
gnutls_protocol_set_enabled

** API and ABI modifications:
No changes since last version.
