libstagefright: avoid audio source to start before audio player after seek

If audio source is started before audio player during seek, audio source
will start allowing the audio data from the beginning (as seekTime for
Audio is maintained in AudioPlayer and is set once we start the audio player)
Once AudioPlayer is started, it sets the seektime and the data starts from seektime.

This change avoids audio source to start before starting audio player.

libstagefright: reset flag to allow buffering

When buffering is 100% or eos is reached, buffering flag
is set.If the playback is seeked back to some location
after EOS, no buffering happen. Without buffering, user experience
is bad in poor network condition.
This also handle file having header at the end. While reading
header EOS get set and buffering is prevented.

Reset the flag to allow buffering during above use cases.

libstagefright: Add flush in reset during LPA playback

-If next operation is performed during LPA playback, delay is
observed before moving to next clip.
-Flush in reset happens only when playback is paused.
-Remove pause check to avoid delay and flush in cases where
next clip has been selected.

libstagefright: Fix for crash during lpa playback

-During lpa playback, flush() is not issued if mReachedOutputEOS
is true. This prevents flush reaching to HAL even during pause
state and causes crash.
-Issue flush() in all cases as these checks are handled in HAL.

libstagefright: Avoid flush if LPA playback is not routed

-On a previously closed LPA playback due to pausetimeout, if

-Check if audio is routed before calling flush to avoid such

libstagefright: Deregister audio flinger client during LPA session close

-Mediaserver crash is observed during BT disconnect.
-Audioflinger client registered during lpa playback is never

audioflinger: Initialize effectspool buffer size during allocation

-Crashes are observed during start of lpa playback with effects
enabled.
-Effectspool buffer size is invalid before initial two writes. If
effectsthread tries to access these buffers in such invalid state
it leads to crash.
-Initialize buffer size to 0 during effectspool buffer allocation.

Frameworks/av: Fix for mediaserver crash in AudioFlinger

- UI freeze is observed while playing LPA clips with sound effects.
- While moving to next clip, effect process is still applying
  effects on last buffers. Meanwhile de-allocating the local buffers
  in DirectAudioTrack destructor on which effects are currently
  applying. Due to this crash is observed in effect process.
- De-allocate buffers once the effects thread is killed.
