Log Message:
gnutls: update to 3.7.2.

* Version 3.7.2 (released 2021-05-29)

** libgnutls: The priority string option %DISABLE_TLS13_COMPAT_MODE was added
   to disable TLS 1.3 middlebox compatibility mode

** libgnutls: The Linux kernel AF_ALG based acceleration has been added.
   This can be enabled with --enable-afalg configure option, when libkcapi
   package is installed (#308).

** libgnutls: Fixed timing of early data exchange. Previously, the client was
   sending early data after receiving Server Hello, which not only negates the
   benefit of 0-RTT, but also works under certain assumptions hold (e.g., the
   same ciphersuite is selected in initial and resumption handshake) (#1146).

** certtool: When signing a CSR, CRL distribution point (CDP) is no longer
   copied from the signing CA by default (#1126).

** libgnutls: The GNUTLS_NO_EXPLICIT_INIT envvar has been renamed to
   GNUTLS_NO_IMPLICIT_INIT to reflect the purpose (#1178). The former is now
   deprecated and will be removed in the future releases.

** certtool: When producing certificates and certificate requests, subject DN
   components that are provided individually will now be ordered by
   assumed scale (e.g. Country before State, Organization before
   OrganizationalUnit).  This change also affects the order in which
   certtool prompts interactively.  Please rely on the template
   mechanism for automated use of certtool! (#1243)

** API and ABI modifications:
gnutls_early_cipher_get: Added
gnutls_early_prf_hash_get: Added
