Add support for XTRA_VERSION_CHECK QMI LOC msg

A new QMI LOC msg is introduced which injects into
the modem a value that determines whether or not
the version of XTRA is to be checked

fixing the SSR recovery race condition

There is a race condition where when startFix is
called right at the time when modem or griffon
subsystem is down, GPS HAL doesn't get the correct
error code, and therefore the right handling.

Mapped ENGINE_DOWN to ENGINE_OFFLINE, as they are
the same; and modified loc_eng_start_handler to
update the state upon the right error code.

There is a one problem though. General failure is
also handled as SSR. This is because of an unhandled
race condition in the kernel, so the error code
returned and propagated is not deterministic enough
for us to tell if this is SSR. Until that fix is in
place, we might have to treat general failure as SSR
although the side effect should be none. Only
semantically incorrect.

loc timer util fix to handle the race condition

loc timer util stop() routine may have race condition
with the timer thread, when timer expires at the same
time stop() routine tries to lock mutex.  The race
condition can go 2 ways:
* timer thread expires, unlocks mutex, context switch,
stop() thread acquires lock, context switch, timer
thread destroys mutex.  Destroy will fail, resulting
mutex leak.
* timer thread expires, unlocks mutex, destroys mutex,
stop() acqures lock, signal, and releases lock. Would
be super rare conditions though.

Fix is that we give 5 seconds for stop() thread to
give up the lock when destroy. After that the timer
thread will release the mutex and go on destroy.
Meanwhile the stop() thread would check the lock
return to move on with signal and unlock.

Fix for CR 692085, error mapping incorrect in one of the cases

eLOC_CLIENT_FAILURE_INTERNAL returned from loc_api_v02 was mapped
to LOC_API_ADAPTER_ERR_FAILUR, however in loc_eng_start_handle it
is LOC_API_ADAPTER_ERR_GENERAL_FAILURE that is being checked for.
Created a new error ID LOC_API_ADAPTER_ERR_INTERNAL specifically
for this error case.

Remove reduntant clearing of GpsLocation memory

GpsLocation memory will now be cleared inside the
Loc Api handler itself, so no need to do it a second
time before calling into the Loc Api handler.
