* Pause instead of stopping music on resign
The [audioSource stop] causes the music to be stopped, and therefore it fails to resume later on a call to [audioSource resume], due to the addition of the if (!stopped) check in resume added in 26a04b38f2
* Don't re-pause music that has already been paused
In this situation:
1. Start game, music plays
2. Switch to Music app, game music paused, start other music
3. Switch to game, game music not resumed due to other music playing
4. Switch to Music app, stop other music
5. Switch back to game, game music should resume due to no other music playing
At step 5 the game music doesn't currently resume. This is because at step 4 when switching to the Music app, the game music gets re-paused (actually isPlaying is false, so systemPaused is set to NO, even though the music *is* still paused). This causes the music to not be resumed at step 5.
This change fixes this, by skipping the pause logic if systemPaused is already true.
Note that this is dependent on https://github.com/cocos2d/cocos2d-x/pull/16178
* Fix typo in previous fix.
* fixed#16170: Random crash in alGenBuffers(AudioCache::readDataTask) at startup.
* Minor fix: should -> may
* Minor fix: updates comments.
* Update comment.
* Comment fix again.
* [audio] Fixes some issues while stop/uncache right after play/preload on OSX/iOS platform.
* Better state control in AudioCache.
* Adds State enum class which contains INITIAL, LOADING, READY, FAILED states.

* Should check whether state is INITIAL in the destructor of AudioCache.
* Adds test case for switching play state frequently.
* Skips invoking reading data callback if cache's state is INITIAL.

[c35fb20] Fixed include.
[cdd9d32] Do mixing by ourself. (TO BE POLISHED)

[80fa2ab] minor fix of the code position of resetting state to State::INITIALIZED
[d9c62f1] underrun fix for PcmAudioPlayer.
[9c2212a] UrlAudioPlayer, playOverMutex should be static, and should be used in update method.
[1519d2e] static variables
[19da936] _pcmAudioPlayer Null pointer check in AudioPlayerProvider.
[e6b0d14] Updates audio performance test.
[fc01dd4] Registers foreground & background event in AudioEngine-inl.cpp(android), the callback should invoke `provider`'s pause & resume method.
[e00a886] TBD: Pause & resume support for PcmAudioPlayerPool.
Since OpenSLES audio resources are expensive and device shared, we should delete all unused PcmAudioPlayers in pool while pause and re-create them while resume.
But this commit isn't finished yet, I don't find a better way to register pause&resume event in AudioEngine module.
[9e42ea3] Interleave mono audio to stereo audio. PcmAudioPlayerPool only contains PcmAudioPlayers with 2 channels.
[3f18d05] Adds a strategy for checking small size of different file formats.
[753ff49] Adds performance test for AudioEngine.
[09d3045] Releases an extra PcmAudioPlayer for UrlAudioPlayer while allocating PcmAudioPlayer fails.
[9dd4477] Using std::move for PcmData move constructor & move assignment.
[6ca3bcb] some fixes:
1) new -> new (std::nothrow)
2) break if allocate PcmAudioPlayer fails
3) renames 'initForPlayPcmData' to 'init'
4) PcmAudioPlayer destructor deadlock if 'init' failed
[54675b6] include path fix.
[a1903ca] More refactorings.
[19b9498] Makes linter.py happy. :)

[6f3839f] minor log output fix in AudioEngine-inl.cpp
[c68bc6c] Don't resample if the sample rate of the decoded pcm data matchs the device's.
[43ca45f] PcmAudioPlayers also need to be removed while they play over, but should not be deleted since their lifecycle is managed by PcmAudioPlayerPool.
