GnuTLS 2.3.4

[Simon Josefsson]

The GnuTLS 2.3.x branch is NOT what you want for your stable system.  It
is intended for developers and experienced users.

My next step is to release a libopencdk-lite, then make a gnutls 2.3.5
that use it, then branch off gnutls_2_4_x and go for a new stable GnuTLS
release in a few weeks.

I tried to make sure there are no ABI/ABI modifications/deletions in
this compared to v2.2.x, but as the changes have been quite large, I may
have missed something.  Note that we don't guarantee ABI compatibility
during development releases, so if there are ABI breaks in this release,
we'll consider those bugs and revert them, rather than bumping the ABI.

Also, we need to figure out how the LGPL opencdk should be handled.  The
only LGPL'ed opencdk is the one included in this release.  There should
probably be an external release of this code.

News in this release:

* Version 2.3.4 (released 2008-03-19)

** Finish renaming of gnutls_certificate_export_x509_cas etc.
They weren't renamed in the public header file.

** Added functions to register a cipher/mac/digest. This allows to 
override the included ones.

** Fix a bunch of compiler warnings.

** API and ABI modifications:
gnutls_crypto_cipher_st: ADDED
gnutls_crypto_mac_st: ADDED
gnutls_crypto_digest_st: ADDED
gnutls_crypto_cipher_register: ADDED
gnutls_crypto_mac_register: ADDED
gnutls_crypto_digest_register: ADDED
GNUTLS_E_CRYPTO_ALREADY_REGISTERED: ADDED

Improving GnuTLS is costly, but you can help!  We are looking for
organizations that find GnuTLS useful and wish to contribute back.
You can contribute by reporting bugs, improve the software, or donate
money or equipment.

Commercial support contracts for GnuTLS are available, and they help
finance continued maintenance.  Simon Josefsson Datakonsult, a
Stockholm based privately held company, is currently funding GnuTLS
maintenance.  We are always looking for interesting development
projects.  See http://josefsson.org/ for more details.
