Update to 2.10.4:

* Version 2.10.4 (released 2010-12-06)

** gnutls-serv: Corrected a buffer overflow. Reported and patch by Tomas Mraz.

** libgnutls: Use ASN1_NULL when writing parameters for RSA signatures.
This makes us comply with RFC3279. Reported by Michael Rommel.

** libgnutls: Reverted default behavior for verification and
introduced GNUTLS_VERIFY_DO_NOT_ALLOW_X509_V1_CA_CRT. Thus by default
V1 trusted CAs are allowed, unless the new flag is specified.

** minitasn1: Updated to Libtasn1 2.9.

** API and ABI modifications:
No changes since last version.
