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 4.3.
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
