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

+  Send data using a network connection.

+  documentation is available online.
+
+  @param [in] s         Socket file descriptor returned from ::socket.
+
+  @param [in] buffer    Address of a buffer containing the data to send.
+    
+  @param [in] length    Length of the buffer in bytes.
+
+  @param [in] flags     Message control flags
+
+  @returns    ::send returns the number of data bytes that were
+              sent and -1 when an error occurs.  In the case of
+              an error, errno contains more details.
