send ULP the position mode if it is valid when ULP handle
is first received. This helps handling a race condition
where ULP handshake happens when a GPS session is about
to happen or already happening.

In order to preserve the ordering of
position reports and status reports from
the GPS engine, status reports are sent
through the ULP too

ULP will no longer be loaded and init'ed from loc eng
HAL. GPS HAL will look for ULP once it completes init
and waits for a msg back once it hears from ULP. This
is done with introduction of UlpProxy. Default proxy
is a no op proxy.

(cherry picked from commit 2eb4ddcae94283df6c6be450c4c070ffd8ff9cd7)
Changes can be highlighted with below summary:
* Split the original LocApiAdapter to LocAdapter and LocApi.
Now different adapter implementations can flexibly connect
to different LocApi;
* LocApi continues to abstract the API binding to RPC or QMI;
* MsgTask which creates and owns a msg Q and a thread, and it
define a LocMsg base msg class. The handler pulls a msg out
of the Q and calls its proc() method. This makes it possible
for msg sender to keep the data in the msg encapsulated, as
it no longer requires a central msg handler who must under-
stand all data format. This used to be where all the compile
time dependencies are tangled together;
* Added Context to bundle MsgTask and LocApi;
* Added LocDualContext specifically for the FLP Location Hal
architecture requirement;
* Placed all the base classes of the above in loc_core folder
/ loc_core namespace / libloc_core.so, so other libraries
can easily use derive from here without having to pull in
the loc_eng implementation, which is a large library to
include or link to;
