Camera: QCOM legacy definitions,HTC cam switch,NO_UPDATE_PREVIEW

Updating Camera parameters, and service with several
compatibility patches:

1., QCOM legacy CameraParameters and functions:
Adding these will make ICS qcomm camera blobs work on JB 4.2.
Use BOARD_USES_QCOM_LEGACY_CAM_PARAMS := true in BoardConfig
to use this.

Also fixes the problem of legacy qcom
camera blobs with recent libcameraservice QCOM_HARDWARE changes,
where the orientation is messed up on first
preview: the fix is leaving out setPreviewWindow(window) for
legacy qcomm cam blobs.

2., Also adding NO_UPDATE_PREVIEW flag for legacy purposes.

3., Adding adding the set orientation patch:
Always set buffers orientation when setting the qcom camera preview window
Fixes the rotated preview on TouchPad

5., Adding more parameters for HTC Explorer

Revert "audioflinger: apply volume on direct track when track is active"

Causes issues with MortPlayer (LPA).  Track starts/resumes playing, but volume is forced to zero, until a track-change occurs.

audioflinger: Fix to release wakelock after closeoutput

-In DirectTrack destructor, closeOutput is called after
releaseWakelock is done. This may sometimes result in
power collapse happening even before actual close
sequence of Audio path is completed and will result
in high power consumption.
-Release wakelock only after closeOutput is done
in directtrack destructor.

Fixed the wrong timestamps issue about camera recording

On emulator, the camera video recording crashes randomly.
It's caused by wrong timestamp when encoding the video frame.
The element of the vector is erased before accessing it.
Therefore, when reading the timestamp from the element,
the memory of the element has been changed.
