gnutls 3.1.0 pre-release

[Nikos Mavrogiannopoulos]

Hello,
 One of the next few weeks I plan to release gnutls 3.1.0. This includes
quite some changes comparing to 3.0.x, the most prominent being:
* Dependence on nettle for RSA PKCS #1 1.5 operations.
* Support for TPM keys (if trousers is available).

The former means that we save quite some code by not reimplementing this
stuff in gnutls. The TPM support means that you can use your TPM chip
to secure your private key similarly to a smart-card. Keys are referred
to by using a (for now custom) URL-like format that looks like:
tpmkey:uuid=58ad734b-bde6-45c7-89d8-756a55ad1891;storage=user
tpmkey:file=/path/to/tpmkey.pem

I've put some pre-release versions at alpha.gnu.org. Please try them and
feel free to report any issues you encounter or any other comments.

A more detailed changelog follows.

* Version 3.1.0pre0 (released 2012-08-05)

** libgnutls: Added direct support for TPM as a cryptographic module
in gnutls/tpm.h.

** libgnutls: requires libnettle 2.5.

** libgnutls: Use the PKCS #1 1.5 encoding provided by nettle (2.5)
for encryption and signatures.

** libgnutls: Added GNUTLS_CERT_SIGNATURE_FAILURE to differentiate between
generic errors and signature verification errors in the verification
functions.

** libgnutls: Added gnutls_pkcs12_simple_parse() as a helper function
to simplify parsing in most PKCS #12 use cases.

** libgnutls: gnutls_certificate_set_x509_simple_pkcs12_file() adds
the whole certificate chain (if any) to the credentials structure, instead
of only the end-user certificate.

** libgnutls: Key import functions such as gnutls_pkcs12_simple_parse()
and gnutls_x509_privkey_import_pkcs8(), return consistently
GNUTLS_E_DECRYPTION_FAILED if the input structure is encrypted but no
password was provided.

** libgnutlsxx: Added session::set_transport_vec_push_function. Patch
by Alexandre Bique.

** tpmtool: Added. It is a tool to generate private keys in the
TPM.

** gnutls-cli: --benchmark-tls was split to --benchmark-tls-kx
and --benchmark-tls-ciphers

** certtool: generated PKCS #12 structures may hold more than one
private key. Patch by Lucas Fisher.

** certtool: Added option --null-password to generate/decrypt keys
that use a NULL password (in schemas that distinguish between NULL
an empty passwords).

** minitasn1: Upgraded to libtasn1 version 2.13.

** API and ABI modifications:
