doc update
certificate verification is performed asynchronously.
Allow null list_size argument in gnutls_certificate_get_peers()
corrected error checking in gnutls_x509_crt_get_extension_data()
initialize string in gnutls_x509_ext_import_basic_constraints().
Print the openpgp DN only when gnutls_openpgp_crt_get_name() failed appropriately.
gnutls_x509_crt_get_signature() will return the correct signature size rather than the max.
changed port of DSA test
tests: pass PKCS12PATH to fix tests in out-of-source builds.

The set_pkcs12_cred used to default to looking for input files in a
subdirectory of the current working directory. When an out-of-source
build is performed, the files reside in a subdirectory of source
directory instead. Set PKCS12PATH to that directory in order to fix the
build.

more files to ignore
do not yet export gnutls_memset().
doc update
invoke-*.texi generation: do not print the bug reports line from autogen.
tools: Replace normal sec-param with medium in documentation.
more sanity checks on signature size
gnutls_x509_crt_get_signature() will use the internal _gnutls_x509_get_signature().

That prevents unnecessary replication of its code.
