release memory while creating window failed.

we should close SDL audio loop before destruct
our audio resource, otherwise, the audio request
loop will use our resource anytime, even those
resources already destructed, which will cause
crash.

The pointer of get() should check null or not.

init pointer variable when declare it

The input sockets are created within the user tmpfs (e.g. /run/user/...).
Files/sockets created there might not be accessible to other users.
Since the input sockets are bind-mounted into the Android container,
it will crash with "Permission denied" when it is unable to access them.

Make sure to give the created directory+socket files appropriate
permissions so they can be accessed within the Android container.

Similar code exists for the anbox_bridge and anbox_audio socket in
  - src/anbox/container/service.cpp (anbox_bridge)
  - src/anbox/audio/server.cpp (anbox_audio)

It breaks build on Alpine/postmarketOS, and is explicitely an error on
more recent version of cpu_features:
https://github.com/google/cpu_features/blob/master/include/cpuinfo_x86.h#L207.

protecting the include with #ifdef fix the problem, as every use of
cpu_features is already protected.

closes https://github.com/anbox/anbox/issues/1436.

`lxc.cap.drop` existed already in LXC1.0, so I assume this should be
backward compatible.

used fixed usb sound card name for unit test before, now use dynamically
name

fixes a error where the message
	[platform_message_processor.cpp:46@process_event_sequence] Failed to parse events from raw string
is followed by a crash at `../src/anbox/rpc/message_processor.cpp:81`.

since buffer_.size() is signed, it could underflow and the safety would
not trigger, leading to a crash.

credits to mntmn for finding the bug and the solution.

if we destruct audio sink without close buffer queue,
we will can`t destruct buffer queue, cause lock
needed by cond already delete by audio sink,
while audio sink destruct.
will cause a deadlock while audio socket disconnectted.

we recognized that add lock will lose more time in submit_layers,
and that lock is unuseful. Remove this lock and use origin logic.

if data size is zero, we don`t need to write it down.
and it can also avoid a crash inside buffer queue.
