[Modules] mod_gnutls 0.5.7

[Nikos Mavrogiannopoulos]

Hello,
 I've just released mod_gnutls 0.5.7. The changes since 0.5.6 are:

** Version 0.5.7 (2010-07-01)
- Force usage of SDBM. For some reason the default in
  my system had issues after reaching a limit of entries.
  SDBM seems stable so force it.

- Optimizations in session caching.

- Added support for session tickets. This allows a
  server to avoid using a session cache and still support
  session resumption. This is at the cost of transporting
  session data during handshake. New option
  GnuTLSSessionTickets [on|off]

- Depend on gnutls 2.10.0 to force support for safe
  renegotiation.
