Add a wrapper function around gnutls_priority_init().

Add a wrapper function around gnutls_priority_init().

It handles errors correctly. I think the old code actually had the
potential to crash if the call to gnutls_priority_init() failed
when using GnuTLS 2.9.10 or newer, because we'd free memory that
had already been freed.

/*
This example demonstrates how to use libpurple-client to communicate
with purple. The names and signatures of functions provided by
libpurple-client are the same as those in purple. However, all
structures (such as PurpleAccount) are opaque, that is, you can only
use pointer to them. In fact, these pointers DO NOT actually point
to anything, they are just integer identifiers of assigned to these
structures by purple. So NEVER try to dereference these pointers.
Integer ids as disguised as pointers to provide type checking and
prevent mistakes such as passing an id of PurpleAccount when an id of
PurpleBuddy is expected. According to glib manual, this technique is
portable.
