appop: reimplement OP_RECORD_AUDIO op check in mediaserver

Obtain the real package name for the calling app from the packagemanager binder and
link to client registry. Also block only openRecord and createEffect (which are the
methods used to record audio), and ignore the createTrack that is used also by
legacy audio apps and isn't related to audio recording.

video: Fix crash during video recording

In pause-resume scenario, MPEG4Writer::start is
called to resume recording, which also resets
start time for writer to -1. If this happens
between two tracks updating the writer start
time, it can end up having the larger of the
start time of the two tracks, which results in
crash later due to assert.

Added change to set mStartTimestampUs to -1 only
when writer is being started, and not resuming from
pause.

StagefrightRecorder: correct the flow of resuming or stopping from pause

1. resume from pause: start the writer first, to avoid frames dropped by
writer due to writer is not started, which caused mosaic frames.

2. stop from pause:  don't start writer, just start encoders and sources,
to avoid unwanted frames are written into clips when stopping in
paused state.

3. recover the pause(dropping frames) in MPEG4Writer.

libstagefright: fix issues in AH263Assembler

- if the received rtp packet belongs to the current
  candidate access unit but arrived later, this packet
  still needs to be inserted into this access unit before
  submitting it. Otherwise this incomplete unit would be
  sent to the decoder and cause some potential errors.

- move the functionality for checking the malformed packet
  and calculating the offset of the payload header to one
  function.

libstagefright: poke the udp hole twice for future incoming udp packets

- only firing off udp packets once to the source address or the endpoint
  could still be limited in some NAT network environment. As a result,
  client can't receive rtp packets over udp.

- send udp packets to both of the two addresses if they are available.

rtsp: keep some damaged access unit to enhance fault tolerance

Make RTSPSource to accept some damaged access units of H263 to enhance
fault tolerance. Without this patch, damaged access can cause failure of
playback.
