tests: move all test-cases into component subdirectories

There are around 300 regression tests, 250 being in tests/bugs. Running
partial set of tests/bugs is not easy because this is a flat directory
with almost all tests inside.

It would be valuable to make partial test/bugs easier, and allow the use
of mulitple build hosts for a single commit, each running a subset of
the tests for a quicker result.

Additional changes made:
- correct the include path for *.rc shell libraries and *.py utils
- make the testcases pass checkpatch
- arequal-checksum in afr/self-heal.t was never executed, now it is
- include.rc now complains loudly if it fails to find env.rc

+#
+# Bug 963678 - Test discard functionality
+#
+# Test that basic discard (hole punch) functionality works via the fallocate
+# command line tool. Hole punch deallocates a region of a file, creating a hole
+# and a zero-filled data region. We verify that hole punch works, frees blocks
+# and that subsequent reads do not read stale data (caches are invalidated).
+#
+# NOTE: fuse fallocate is known to be broken with regard to cache invalidation
+# 	up to 3.9.0 kernels. Therefore, FOPEN_KEEP_CACHE is not used in this
+#	test (opens will invalidate the fuse cache).
