Gallery2: camera: disable all camera controls ASAP when swtich the camera

Camera switch button is a pieItem, there is a fadeInOut animation for these
kinds of menus. And the onClick event deliver to upper layer happens after
the end of the animation which lasts 600ms. We should add another event
callback before the animation to disalbe all camera controls as soon as
possible.

Camera: Fix camcorder crash during pause and resume

When camcorder is suspended in background, if it receives resume
and pause event in very short interval, crash will happen.
After receiving resume event, the onresume method will be called,
and it will start another thread for starting preview. And soon,
the main thread receives pause event, the onpause method which will
close camera is called.
There will be a racing between the main thread and start preview
thread. If close camera get done first, crash will be observed.
To avoid the racing, the close camera operation should wait for the
start preview operation, and the join method is used here for
synchronization.

Camera: Fix crash during open and close camera

When we open camera for the second time after opening camera,
switching to camcorder and exit camcorder rapidly, crash will
be observed. It's due to the assertion of double open.
When app receives pause event, it should cancel the switch
animation, as we as it's listener.

Gallery2: reduce the latency between cam&camcorder switch

There are animations of fadeIn and fadeOut effect when switching
from camera to camcorder or vice-versa which all last 300ms, thus
the black UI observed too long. Set the animator duration to a tiny
value for reducing this latency.

camera: Fix camera startup racing with orientation change

 * When launching the camera via the lock screen widget on some devices,
   the orientation change shows up late, and we get an
   onConfigurationChanged in the middle of setting up the textures,
   causing an infinite wait in the UI thread.
 * Ignore these events until the preview is up and running, orientation
   will be checked later.
