[Modules] mod_gnutls: does gnutls_allocate_* the counterpart gnutls_free_*

[Hardy Griech]

Hi (Nikos),

after extending mod_gnutls to allow TLS-PSK and some testing, I'm 
wondering if all the gnutls_allocate_* need a gnutls_free_* to avoid 
memory leaks.

Actually there must be a leak in mod_gnutls, because my test client 
which continuously connects / transfers / disconnects makes my server 
(with mod_gnutls) consume more and more memory.

Any suggestions?

Regards

Hardy
