Add new file with common functions for tests to use.
- loads config file
- checks for mcexec etc
- checks for LTP and OSTEST if required
- handle mcstop / mcreboot if required, and provide function for it
At the same time, make a few changes to mck_test_config:
- move to ~/.mck_test_config
- add boot params to the config, tests the require specific params can
overwite it
- make the config "set-if-variable-is-empty", so someone can overwrite
any param by setting the environment value e.g. LTP=.... ./test.sh
will use the value given

We had a deadlock between:
- free_process_memory_range (take lock) -> ihk_mc_pt_free_range ->
... -> remote_flush_tlb_array_cpumask -> "/* Wait for all cores */"
and
- obj_list_lookup() under fileobj_list_lock that disabled irqs
and thus never ack'd the remote flush
The rework is quite big but removes the need for the big lock,
although devobj and shmobj needed a new smaller lock to be
introduced - the new locks are used much more locally and
should not cause problems.
On the bright side, refcounting being moved to memobj level means
we could remove refcounting implemented separately in all object
types and simplifies code a bit.

This optimization make the offloading thread quickly yield to
another thread. Without this, it yileded only after the interval timer
set the rescheduling flag.

Defining C structures for the following objects:
(1) Remote and local context
(2) Stack of system call arguments / return values

(1) Add --enable-uti option. The binary-patch library is
preloaded with this option.
(2) Binary-patching is done by syscall_intercept developed by Intel
This commit includes the following fixes:
(1) Fix do_exit() and terminate() handling
(2) Fix timing of killing mcexec threads when McKernel thread calls terminate()

Set PROT_EXEC to host VMA because uti needs PROT_EXEC for text VMAs.
Meanings of prot bits of Host VMA has been changed as follows.
RWX: No mapping or RW mapping
RX: Read only mapping
This is because this is a normal case since terminate() is changed so
that it first kills all mcexec threads and then kill McKernel threads.

It is accompanied by the following fixes:
(1) Fix put ppd locations in mcexec_wait_syscall()
(2) Move put ptd to end of mcexec_terminate_thread_unsafe() and mcexec_ret_syscall()
(3) Add debug messages for ptd add/get/put
(4) Fix ptd-add/get/put matching in mcexec_wait_syscall()
* Skip put when woken-up from wait_event_interruptible() by signal
