Add Libtap as a bundled library (does not change any behaviour without --enable-libtap)

Detects system library as pre-1.4.13 and does not install the built-in library anymore

Tested on:
  - Linux x86_64, with and without local libtap (System libtap installed)
	- Linux x86, with and without local libtap (System libtap NOT installed)
  - Solaris SPARC, with and without local libtap, with and without system libtap installed

+NAME
+     tap -- write tests that implement the Test Anything Protocol
+
+SYNOPSIS
+     #include <tap.h>
+
+DESCRIPTION
+     The tap library provides functions for writing test scripts that produce
+     output consistent with the Test Anything Protocol.  A test harness that
+     parses this protocol can run these tests and produce useful reports indi-
+     cating their success or failure.
