Per-slot rotation and mirror in the camera settings #201
Description
A general setting per slot: rotate 0/90/180/270° and mirror. It is useful for cameras mounted sideways (corridor view) or upside down (ceiling), and for toys.
Deferred: so far the only request is for one toy, and that is handled inside the toy's path (#200). Pick this up when a camera user asks for it. Notes:
- H.264/H.265:
MediaFormat.KEY_ROTATION(Android 6+) or the view's transform; MJPEG: when drawing. - The debug snapshot, screenshot, grid cells and zoom/pan (fix: single view on a SurfaceView instead of a TextureView (#76) #185) must follow the rotation.

Note from #215: rotated MJPEG (
?rotate=) is drawn through the bitmap path, because the single view's SurfaceView can't turn a hardware decoder's output. When rotation becomes a per-slot setting here, it should also work with hardware decoding (H.264/H.265 and hardware JPEG), e.g. through a GL or TextureView path for rotated slots only.feat: per-slot Turn and Mirror in the camera settings, for H.264/H.26…

Turn: PR #225 (ready for review). Mirror is split out to #226: the video surface cannot be mirrored without a separate drawing path.

Turn is in v2 2.17 (PR #225): per-slot Auto/0°/90°/180°/270° in the camera settings, for H.264/H.265 (Android 6+) and MJPEG, in the single view and the grid, snapshots and screenshots included. Mirror continues in #226.
