I chose the RFC format just because the patch was initially for
experimental purpose.  Using _gnutls_session_pack() would be definitely
better.

I've just tried to make use of the internal format, the code became much
simpler (which reduced ~100 lines).  Thanks for the suggestion.

Absolutely.  I'll post a new patch shortly, with other polishments
(adding interface docs, etc.).
