-changes by plugwash (20030728)\r
-* created handlefdtrigger virtual method in tlasio (overridden in tlsocket) and moved a lot of code from messageloop into it\r
-* changed tlasio to tlasio\r
-* split fdhandle into fdhandlein and fdhandleout\r
-* i now use fdsrmaster and fdswmaster instead of rebuilding the lists every loop\r
-* split lsocket.pas into lsocket.pas and lcore.pas\r
-\r
-\r
-changes by beware (20030903)\r
-* added getxaddr, getxport (local addr, port, as string)\r
-* added getpeername, remote addr+port as binary\r
-* added htons and htonl functions (endian swap, same interface as windows API)\r
-\r
-beware (20030905)\r
-* if connect failed (conn refused) set state to connected and call internalclose, to get closed handler (instead of fdclose)\r
-* (lcore) if closing the fd's in internalcose, set fd's to -1 because closing an fd makes it invalid\r
-\r
-beware (20030927)\r
-* fixed: on connect failed, tried to close fdhandle's which were already set to -1, added check\r
-\r
-beware (20031017)\r
-* added getpeeraddr, getpeerport, remote addr+port as string\r
