Camera: SoftwareHDR: Reduce mem usage and let exposure time get tuned

http://review.cyanogenmod.org/#/c/32214/
___________________

- The memory usage has been reduced. Instead of doing 3 bitmaps and
  keeping them in memory, only one bitmap is used and recycled once
  copied to the renderscript allocation.
  In counterpart, I had to remove the software (non-RS) processing.
  I haven't seen any issue of devices disliking RenderScript, so
  I think it's fine.

- I added a config overlay to set the exposure settle time between
  the shots. Some devices are faster than others (ZSL devices can
  take less than 1 second, the previous value). I set this to 0.8
  seconds by default, which works fine on i9100/n7000.

camera: SoftHDR: Use parallel processing

http://review.cyanogenmod.org/#/c/32228/
___________
On an idea from Steve Kondik, the RS script now uses
parallel processing via rsForEach, processing every
line of the image in multiple threads.

Util: Disable software HDR if the camera HAL actually supports it

Defaulting to disabling a functional camera capability and replacing
it with an inferior implementation is a bad idea
