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

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.

libstagefright: Unbreak OMAP4 encoders

The "manual" construction of the h264 codec data is only needed
on OMAP3. Execution of this code on OMAP4 breaks the mpeg4 header
generation
