Modifications to fix some networking/endian issues on PPC OSX.
* added sockaddr_clear() function to zero network addresses before use. * used this function in p3connmgr. * added htonll() and ntohll() functions to rsnet.h with compile-time ENDIAN checking * use htonll() and ntohll() in serialiser. * added net_test.cc to check network/endian/inet_addr issues. git-svn-id: http://svn.code.sf.net/p/retroshare/code/trunk@328 b45a01b8-16f6-495d-af2f-9b41ad6348cc
