Moved support routines from iscsi-test to iscsi-support,
in preperation for sharing non-main functions.
Now main() is seperate from guts of testing.
Added guts of new cunit-based main routine
CUnit tests now working for first 2 suites, but
Makefile.am not correct yet.
Merge remote branch 'gonzoleeman/cunit' into cunit
Add check for libcunit and only build the test suite if libcunit is available
TESTS: Add different log levels to the TUR test test suite and see how it looks

Add different log levels and update the TUR testsute.
Update the helper for testunitready() so that it
* prints FAILURE messages for normal and verbose levels
* prints selfdocumenting messages for which SCSI command it sends and the expected result for the verbose level
TESTS: Update the READ10 tests for the new test tool
TEST: Add a \n to the start of READ10_flags logging
TEST: Add a new flag -V that enables verbose logging off the SCSI commands used and if they succeeded or failed
