[PATCH 1/2] Test framework take two.
This adds t/ directory to host test suite, a test helper library and a basic set of tests. Petr Baudis raised many valid points at the earlier attempts in git mailing list. This round, test-lib.sh has been updated to a bit more modern style, and the default output is made easier to read. Also included is one sample test script that tests the very basics. This test has already found one leftover bug missed when we introduced symlink support, which has been fixed since then. The supplied Makefile is designed to run all the available tests.

+test_description='Test the very basics part #1.
+
+The rest of the test suite does not check the basic operation of git
+plumbing commands to work very carefully. Their job is to concentrate
+on tricky features that caused bugs in the past to detect regression.
+
+This test runs very basic features, like registering things in cache,
+writing tree, etc.
+
+Note that this test *deliberately* hard-codes many expected object
+IDs. When object ID computation changes, like in the previous case of
+swapping compression and hashing order, the person who is making the
+modification *should* take notice and update the test vectors here.
