Move ziltest.sh to the ZTS framework

The ziltest.sh script is a test case designed to verify the correct
functioning of the ZIL.  For historical reasons it was never added
to the test suite and was always run independantly.

This change rectifies that.  The existing ziltest.sh has been
translated in to `slog_015_pos.ksh` and added to the existing
slog test cases.

+# DESCRIPTION:
+#	Verify slogs are replayed correctly.  This test is a direct
+#	adaptation of the ziltest.sh script for the ZFS Test Suite.
+#
+#	The general idea is to build up an intent log from a bunch of
+#	diverse user commands without actually committing them to the
+#	file system.  Then copy the file system, replay the intent
+#	log and compare the file system and the copy.
+#
+#	To enable this automated testing of the intent log some minimal
+#	support is required of the file system.  In particular, a
+#	"freeze" command is required to flush the in-flight transactions;
+#	to stop the actual committing of transactions; and to ensure no
+#	deltas are discarded. All deltas past a freeze point are kept
+#	for replay and comparison later. Here is the flow:
+#
+# STRATEGY:
+#	1. Create an empty file system (TESTFS)
+#	2. Freeze TESTFS
+#	3. Run various user commands that create files, directories and ACLs
+#	4. Copy TESTFS to temporary location (TESTDIR)
+#	5. Unmount filesystem
+#	   <at this stage TESTFS is empty again and unfrozen, and the
+#	   intent log contains a complete set of deltas to replay it>
+#	6. Remount TESTFS <which replays the intent log>
+#	7. Compare TESTFS against the TESTDIR copy
+#
+

+
+log_assert "Replay of intent log succeeds."
