Add mutex in function Send() and OnTimeout() to do mutual
exclusive access on lpm_wake_deasserted.
If lpm_wake_deasserted is out of sync with the actual
wake state, then platforms which use the lpm hint
will break.
Bug: 64299848
Test: run affected platform for a long period of time
and find that hci commands do not time out

Do not crash in the vendor layer. The stack will crash
when it fails to initialize.

Opening the serial port(s) returns -1 when it fails, check
that the number of file descriptors is greater than 0 and
less than the size of the array.

The vendor open interface command returns the total number
of FDs opened. (2 or 4 if the interface is MCT)
However, the list of FDs is always 4 in either case. If the
open command returns 2, the FDs are shared cmd/event and
data in/out.
2 FDs example
[41, 41, 42, 42]
4 FDs example
[41, 42, 43, 44]
If we condition the registration of ACL_IN on the total
number of FDs, then 2 FD MCT interfaces will not get data.

Test: manual, pairing is quick and data does transfer

Some devices still use MCT as their UART protocol, so
we need to bring it forward to the fresh new HAL.
Also, adding tests for H4 while I'm here.
Test: new unit tests pass and a device using MCT now
boots BT again \o/

This ensures the vendor library can release any wakelocks held and
perform any additional cleanup steps as necessary.

Implement low power mode using timeouts from the interface.
Test: Boots, Bluetooth turns on/off,
Instrumented bt_vendor library shows power management
calls.
