After this patch anyone should be able to build Fluoride on Linux.

Currently we use Android-specific property_get and property_set
through the code. This patch adds osi_property_get and osi_property_set
that is encapsulating all external dependencies. This is step further
for errorless compilation on linux.

This patch adds missing osi_module.c file. Without it Fluoride

Change-Id: Id7454450c1ce2164001a1f9ca0b91f18d84e3fd6

This patch changes how HID is initialized.
Up till now, HID discovery was intricately chained,
to make sure two operations are not scheduled at same time.
From now on, all discovery is done and all operations are
scheduled for execution right away. There is separate set
of functions making sure all operations will be executed
without collisions.

This patch also removes BTA_HH_SCPP_INST_DEF, which was
used as hardcoded service id.

This patch changes how GATTC is structured. Up till now, it
contained tBTA_GATTC_CACHE and tBTA_GATTC_CACHE_ATTR. Those
structures were so ugly, someone hide them inside internal
header, to make sure noone would ever access them from outside
GATTC. They are now replaced with:
tBTA_GATTC_SERVICE,
tBTA_GATTC_CHARACTERISTIC,
tBTA_GATTC_DESCRIPTOR and
tBTA_GATTC_INCLUDED_SVC.

Those looks much better, and were made globally avaliable.
Thanks to way they're build, we no longer need set of access
methods, which were also very ugly:
BTA_GATTC_GetFirstChar
BTA_GATTC_GetNextChar
BTA_GATTC_GetFirstIncludedService
etc.

This patch breaks HID, DO NOT SUBMIT without HID refactor.

* changes:
  Remove bta_gattc_id2handle
  Use attribute handle instead of id in GATT cache
  HID multi-device refactoring
  GATT cache storage refactoring
  Remove dead methods and callbacks
  Simplify UUID handling in GATT cache

If L2CA_ConnectReq() failed, make sure that
we cleanup the lcid cache state after the
affected p_mcb.

Also, extra check and a log message inside function
rfc_check_send_cmd().

Various users of fixed_queue's do not free the lists properly after
using them. As a result two event fd's leak for each fixed_queue that
is not free'd, as fixed_queue contains two semaphores.

This can lead to run-away file descriptor allocation and an eventual
hard limit leading to various undefined behaviours.

Use case:
A2DP playback becomes choppy after long hours of testing.

Steps:
1. installed 3rd party app that performs recurring LE scans.
2. Leave phone to run overnight.
3. After 24h+, connect a Bluetooth headset and music is very choppy.

Root cause:
The memory allocation tracker has support for double free check
where it stores all allocations in hash map but it never get
removed to track double free issue, A2DP memory allocation is
taking more time and leading to choppyness.

Fix:
Free the hash map entry to avoid memory leak from
allocation tracker.

Added a function to get the device class to use with pair events.
Also update check_cod_hid as it was only being used with COD_HID_MAJOR.
Also fixed an issue with pair event timestamps where they were
using the wrong clock.

Now that the instance id is equal to handle, we no longer need this
mapping function.

Bug: 27455533
Change-Id: I6760f8fc81460df8520d4ebf1899ed256ce5ad1e

Currently we generate an id for each GATT attribute. Those ids
are used to differentiate between attributes that have the same
UUID. We need to get rid of those ids because it won't work with
partial GATT database updates due to "service change"
notifications. Instead, attribute handles, which are unique
across the whole GATT database will be used.

This is first patch in series to achieve that. It gets rid
of id generation, and just assigns handle in place of ids inside
of gatt cache. Upcoming patches will change the GATT cache API
and eventually get rid of "id" completly.

Bug: 27455533
Change-Id: I74c10872ecc223329b8ac7fef4085963bf272624

We don't really support multiple HID services in same device.
We shouldn't use default value 0 for service id.
We shouldn't merge service id and characteristic id into one field,
as it's done not right right now.

Change-Id: I46cc1b62bb2c7393e62f3b1a8e4650706954a066

Currently when storing GATT cache into file, we save it piece
after piece, max 10 elements at once. This is not necessary,
we have enough space to just save all at once.
Also the logic doesn't need to be so complicated - no need
to state machine for such simple task.

Audio focus handling for A2DP sink currently split between Fluoride and

decide policies, we move all such decisions to the upper layer.

Function btm_send_pending_direct_conn() dequeues tL2C_LCB
entries from the conn_pending_q queue and calls the processing
function.
However, there is the possilility of a race condition
and releasing the entry by l2cu_release_lcb() before it is processed.
Now tL2C_LCB that are not in_use are ignored.

Update the l2cu_initialize_fixed_ccb() implementation so
it returns only entries that are properly initialized.
In some complex scenarios, the p_lcb->p_fixed_ccbs[] array
might contain an entry that has been released by l2cu_release_ccb(),
and such entry cannot be reused as-is.

Fix a crash condition that is triggered when the firmware
configuration takes too long:
 1. The startup_timer expires, and it resets startup_future to NULL
 2. The delayed firmware_config_callback is received, and it
    tries to use the startup_future pointer (already set to NULL).
