* Adding more detailed flags to each connection. * Cleaned up unneeded stuff from p3LinkMgr. * Added rswin.h includes before openssl - allows compilation using std Win OpenSSL. * Added getConnectFlags() to Net Base. * removed net_attempt and associated obsolete variables from pqissl * Made NetBinInterface protected in pqiperson (is this okay?) git-svn-id: http://svn.code.sf.net/p/retroshare/code/branches/v0.5-dhtmods@4767 b45a01b8-16f6-495d-af2f-9b41ad6348cc

/***************************** pqi Net SSL Interface *********************************
|
|
* This provides the base SSL interface class,
|
|
* and handles most of the required functionality.
|
|
*
|
|
* there are a series of small fn's that can be overloaded
|
|
* to provide alternative behaviour....
|
|
*
|
|
* Classes expected to inherit from this are:
|
|
*
|
|
* pqissllistener -> pqissllistener (tcp only)
|
|
* -> pqixpgplistener (tcp only)
|
|
*
|
|
* pqissl -> pqissltcp
|
|
* -> pqissludp
|
