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

+Most of the tests follow the same pattern.
+
+ * test.pl that uses Test::More, and demonstrates whatever functionality 
+   that we're trying to test.  This is the reference code.
+
+ * test.c, which tests the libtap reimplementation of the same functionality.
+
+ * test.t, which compiles the .c program, runs both test scripts, and then 
+   diffs their output to make sure it's identical.
+
+   Right now, test.t is identical in every directory.  This sucks somewhat.
+   It should either be a symlink to a common script
