  gnutls_psk_server_get_username

New functions to set PSK callback:
  gnutls_psk_set_server_credentials_function
  gnutls_psk_set_client_credentials_function

Use size_t instead of int for output size parameter:
  gnutls_srp_base64_encode
  gnutls_srp_base64_decode

* Version 1.2.11 (2006-05-11)
- The function gnutls_x509_crt_to_xml is not supported any more, and
  return an internal error.  The reason is that the function called
  internal libtasn1 functions which are no longer exported from
  libtasn1.
- Updated libtasn1 requirement to 0.3.4 and refreshed internal mintiasn1.
- Updated gnulib compatibility files.
- Fixed _gnutls_x509_get_raw_crt_expiration_time and
  _gnutls_x509_get_raw_crt_activation_time to return (time_t)-1 on errors.
- API and ABI modifications:
  No changes since last version.

* Version 1.2.10 (2006-02-09)
- Fix read out bounds bug in DER parser.  Reported by Evgeny Legerov
  <admin@gleg.net>, and debugging help from Protover SSL.
- Libtasn1 0.2.18 is now required (contains the previous bug fix).
  The included version has been updated too.
- Fix gnutls-cli STARTTLS hang when SIGINT is sent too quickly, thanks to
  Otto Maddox <ottomaddox@fastmail.fm> and Nozomu Ando <nand@mac.com>.
- Corrected a bug in certtool for 64 bit machines. Reported
  by Max Kellermann <max@duempel.org>.
- Corrected bugs in gnutls_certificate_set_x509_crl() and
  gnutls_certificate_set_x509_trust(), that caused memory corruption if
  more than one certificates were added. Report and patch by Max Kellermann.
- Fixed bug in non-blocking gnutls_bye(). gnutls_record_send() will no
  longer invalidate a session if the underlying send fails, but it will
  prevent future writes. That is to allow reading the already received data.
  Patches and bug reports by Yoann Vandoorselaere <yoann@prelude-ids.org>

* Version 1.2.9 (2005-11-07)
- Documentation was updated and improved.
- RSA-MD2 is now supported for verifying digital signatures.
- 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
  GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD2 or GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD5
  flags when verifying certificates.  Naturally, this is not
  recommended default behaviour for applications.  To enable the
  broken algorithms, call gnutls_certificate_set_verify_flags with the
  proper flag, 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.
- Some changes in the certificate receiving part of handshake to prevent
  some possible errors with non-blocking servers.
- Added numeric version symbols to permit simple CPP-based feature
  tests, suggested by Daniel Stenberg <daniel@haxx.se>.
- 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_MD2,
GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD5: New gnutls_certificate_verify_flags values.
                                  Use when calling
                                  gnutls_x509_crt_list_verify,
                                  gnutls_x509_crt_verify, or
                                  gnutls_certificate_set_verify_flags.
GNUTLS_CERT_INSECURE_ALGORITHM: New gnutls_certificate_status_t value,
                                used when broken signature algorithms
                                is used (currently RSA-MD2/MD5).
LIBGNUTLS_VERSION_MAJOR,
LIBGNUTLS_VERSION_MINOR,
LIBGNUTLS_VERSION_PATCH,
LIBGNUTLS_VERSION_NUMBER: New CPP symbols, indicating the GnuTLS
			  version number, can be used for feature existence
			  tests.

- Added the option --get-dh-params to certtool, in order to get the
  parameters included in the library primes and generators.

  allow only trusted Version 1 CAs and introduced
  GNUTLS_VERIFY_ALLOW_ANY_X509_V1_CA_CRT which has the old semantics.
- Nettle self tests now build properly, reported by Pierre

  to specify certificates for the handshake without storing them to the
