Ticket #1032:

• Initial version of server domain name verification:
  • Updated SSL certificate info, especially identities info
  • Updated verification mechanism as in the specifications in ticket desc.
  • Added server domain name info in pjsip_tx_data.
  • Added alternative API for acquiring transport and creating transport of transport factory to include pjsip_tx_data param.
  • Server identity match criteria:
    • full host name match
    • wild card not accepted
    • if identity is URI, it must be SIP/SIPS URI
• Initial version of transport state notifications:
  • Added new API to set transport state callback in PJSIP and PJSUA.
  • Defined states: connected/disconnected, accepted/rejected, verification errors.
• Minors:
  • Updated SSL socket test: dump verification result, test of requiring client cert, and few minors.
  • Updated test cert to include subjectAltName extensions.
  • Added SSL certificate dump function.
  • Updated max number of socket async operations in Symbian sample apps (RSocketServ::Connect()) to 32 (was default 8).
