Add Socket Libraries.
Add Posix functions for porting compatibility. Fix compliance issues with ISO/IEC 9899:199409 New Functions: setenv(), fparseln(), GetFileNameFromPath(), rename(), realpath(), setprogname(), getprogname(), strlcat(), strlcpy(), strsep(), setitimer(), getitimer(), timegm(), getopt(), basename(), mkstemp(), ffs(), vsnprintf(), snprintf(), getpass(), usleep(), select(), writev(), strcasecmp(), getcwd(), chdir(), tcgetpgrp(), getpgrp(), gettimeofday(), bcopy(), git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@12061 6f19259b-4bc3-4df7-8a09-765794883524
