Update to 1.4.0:

* Version 1.4.0 (released 2006-05-15)

** Remove GnuTLS 0.8.x compatibility functions.

** The libgcrypt RNG is initialized in gnutls_global_init().

** TLS/IA API changes from Emile van Bergen.
A dummy credential structure is not needed now, if you wish to use the
low-level TLS/IA API, simply call gnutls_ia_enable to enable TLS/IA on
a session.

** The self-tests are now run under valgrind, if it is installed.

** Libtasn1 is updated to 0.3.4, and that version is now required.

** The command line tools now use getaddrinfo and support IPv6.

** API and ABI modifications:
_gnutls_x509_get_raw_crt_activation_time,
_gnutls_x509_get_raw_crt_expiration_time: Removed.
gnutls_ia_require_inner_phase: Removed, replaced by gnutls_ia_enable.
gnutls_ia_enable: Added.
