New Revision: 41812

URL: http://svn.digium.com/view/asterisk?rev=41812&view=rev
Log:
Do not export any symbols from chan_h323 to not create cross-bindings
on module load between chan_h323 and openh323/pwlib libraries because
some classes from openh323/pwlib automatically generates code in chan_h323
too. Forced unload of chan_h323 breaks bindings on openh323/pwlib and
causes crashes on Asterisk shutdown.

Good reading about DSO in GNU/UNIX environment is Ulrich Drepper's book "How
to write shared libraries" (http://people.redhat.com/drepper/dsohowto.pdf)
