Vendor HAL Threading Model
==========================
The vendor HAL service has two threads:
1. HIDL thread: This is the main thread which processes all the incoming HIDL
RPC's.
2. Legacy HAL event loop thread: This is the thread forked off for processing
the legacy HAL event loop (wifi_event_loop()). This thread is used to process
any asynchronous netlink events posted by the driver. Any asynchronous
callbacks passed to the legacy HAL API's are invoked on this thread.
Synchronization Concerns
========================
wifi_legacy_hal.cpp has a bunch of global "C" style functions to handle the
legacy callbacks. Each of these "C" style function invokes a corresponding
"std::function" version of the callback which does the actual processing.
The variables holding these "std::function" callbacks are reset from the HIDL
thread when they are no longer used. For example: stopGscan() will reset the
corresponding "on_gscan_*" callback variables which were set when startGscan()
was invoked. This is not thread safe since these callback variables are
accesed from the legacy hal event loop thread as well.
Synchronization Solution
========================
Adding a global lock seems to be the most trivial solution to the problem.
a) All of the asynchronous "C" style callbacks will acquire the global lock
before invoking the corresponding "std::function" callback variables.
b) All of the HIDL methods will also acquire the global lock before processing
(in hidl_return_util::validateAndCall()).
Note: It's important that we only acquire the global lock for asynchronous
callbacks, because there is no guarantee (or documentation to clarify) that the
synchronous callbacks are invoked on the same invocation thread. If that is not
the case in some implementation, we will end up deadlocking the system since the
HIDL thread would have acquired the global lock which is needed by the
synchronous callback executed on the legacy hal event loop thread.

// PNO ENTRY = crc24(3 bytes) | flags>>3 (5 bits) | auth flags(3 bits)

// should be scored and the wifi_epno_handler on_network_found callback should be called with

// frequency range (min5GHz_rssi and min24GHz_rssi for 5GHz and 2.4GHz networks respectively).

// When connected the scan results shall be reported only if the score of any network in the scan
// is greater than that of the currently connected BSSID.

// + secure_bonus (if the network is not open)

* implemented manually in WiFi HAL (see changeFirmwareMode in
* WifiChip::handleChipConfiguration).
*
* Supported combinations are defined in device's makefile, for example:
* WIFI_HAL_INTERFACE_COMBINATIONS := {{{STA, AP}, 1}, {{P2P, NAN}, 1}},
* WIFI_HAL_INTERFACE_COMBINATIONS += {{{STA}, 1}, {{AP}, 2}}
* What means:
* Interface concurrency combination 1: 1 STA or AP and 1 P2P or NAN concurrent iface
* operations.
* Interface concurrency combination 2: 1 STA and 2 AP concurrent iface operations.
*
* For backward compatibility, the following makefile flags can be used to
* generate combinations list:
* - WIFI_HIDL_FEATURE_DUAL_INTERFACE
* - WIFI_HIDL_FEATURE_DISABLE_AP
* - WIFI_HIDL_FEATURE_AWARE
* However, they are ignored if WIFI_HAL_INTERFACE_COMBINATIONS was provided.
* With WIFI_HIDL_FEATURE_DUAL_INTERFACE flag set, there is a single mode with
* two concurrency combinations:
* Interface Concurrency Combination 1: Will support 1 STA and 1 P2P or NAN (optional)
* concurrent iface operations.
* Interface Concurrency Combination 2: Will support 1 STA and 1 AP concurrent
* iface operations.
*
* The only dual-mode configuration supported is for alternating STA and AP
* mode, that may involve firmware reloading. In such case, there are 2 separate
* modes of operation with 1 concurrency combination each:
* Mode 1 (STA mode): Will support 1 STA and 1 P2P or NAN (optional)
* concurrent iface operations.
* Mode 2 (AP mode): Will support 1 AP iface operation.
*
* If Aware is enabled, the concurrency combination will be modified to support either
* P2P or NAN in place of just P2P.
