Hi all,

On FirefoxOS(gonk), hw codecs and camera hw are loaded in application's
process. These hardwares request high privilege(like system) to the
processes.

This produce following restrictions and problems.
- normal web contents could not use the hardwares capability directly.
- an application needs to have "deprecated-hwvideo" or "camera" permission
in manifest.webapp to use them.
- could not apply the privilege to an application durinng its running. It
needs theprocess restart.
- camara hw might be loaded from multiple processes. In android, camera hw
is loaded from only one process(mediaserver).
- application processes with deprecated-hwvideo/camera permission have too
high privilege

IMHO, it is necessary to remove the restrictions. Then, I created bug
803471, bug 798202 and bug 798773 for the problems.
camera hw handling still has a problem, though they basically work on my
phone.

Is it a correct way to go? Can I have comments about them?
