[Help-gnutls] 1.2.9 release candidate

Hi all.  There has been larger changes than usual in CVS, so I thought
I'd roll a release candidate before releasing 1.2.9.  I'll release
this during the next week if there are no problems.  Please test:


In particular, I want to know how this works on minw32, and whether
the MD2/MD5 stuff works.

Note: Don't use --with-builtin-crypto, it doesn't implement HMAC yet,
so it doesn't even pass the self tests.  Hopefully, I'll fix this
before the release.

I have tested this successfully on alphaev67-unknown-linux-gnu,
i686-pc-linux-gnu, sparc-sun-solaris2.9, i386-unknown-freebsd4.11, and

NEWS entries below.  Suggestions on the text is also appreciated.


- Documentation was updated and improved.
- MD2 is now supported.
- Due to cryptographic advances, verifying untrusted X.509
  certificates signed with RSA-MD2 or RSA-MD5 will now fail with a
  GNUTLS_CERT_INSECURE_ALGORITHM verification output.  For
  applications that must remain interoperable, you can use the
  flags when verifying certificates.  Naturally, this is not
  recommended to be the default behaviour.  For example, call
  gnutls_certificate_set_verify_flags with these flags to change the
  verification mode used by gnutls_certificate_verify_peers2.
- Make it possible to send empty data through gnutls_record_send,
  to align with the send(2) API.
- The (experimental) low-level crypto alternative to libgcrypt used
  earlier (Nettle) has been replaced with crypto code from gnulib.
  This leads to easier re-use of these components in other projects,
  leading to more review and simpler maintenance.  The new configure
  parameter --with-builtin-crypto replace the old --with-nettle, and
  must be used if you wish to enable this functionality.  See README
  under "Experimental" for more information.  Internally, GnuTLS has
  been updated to use the new "Generic Crypto" API in gl/gc.h.  The
  API is similar to the old crypto/gc.h, because the gnulib code were
  based on GnuTLS's gc.h.
- Fix compiler warning in the "anonself" self test.
- API and ABI modifications:
gnutls_x509_crt_list_verify: Added 'const' to prototype in <gnutls/x509.h>.
                             This doesn't reflect a change in behaviour,
                             so we don't break backwards compatibility.
GNUTLS_MAC_MD2: New gnutls_mac_algorithm_t value.
GNUTLS_DIG_MD2: New gnutls_digest_algorithm_t value.
GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD5: New gnutls_certificate_verify_flags values.
                                  Use when calling
                                  gnutls_x509_crt_verify, or
GNUTLS_CERT_INSECURE_ALGORITHM: New gnutls_certificate_status_t value,
                                used when broken signature algorithms
                                is used (currently RSA-MD2/MD5).
