Rework of AuthSSL: cleanup and split up. * Split out independent SSL functions into sslfns.h / sslfns.cc * Reworked SSL certificate storage. * Reworked SignDataBin / VerifyDataBin (fixed memory leaks). * Removed funny code: /* cert->cert_info->key->pkey is NULL */ - just use X509_get_pubkey() instead. * Removed lots of old code. * Fixed up Mutex usage in AuthSSL - which was random. * Removed certificates from tlvSignature serialiser obj. * removed certificates from p3distrib messages. * Starting removing "unused parameter" compiler warnings. * Various related changes to make libretroshare compile. git-svn-id: http://svn.code.sf.net/p/retroshare/code/trunk@3222 b45a01b8-16f6-495d-af2f-9b41ad6348cc
