am: Allow more hidden apps on devices with lots of RAM

 * If more than 1.5GB is present, allow up to 40 hidden apps.
 * Number is somewhat arbitrary, but was found to work well on D2.
 * Also look at the sys.mem.max_hidden_apps value if given.

Prefer 16bpp formats for opaque bitmaps

Configure BitmapFactory to prefer RGB565, which will make it
use that format for all opaque assets loaded by it with standard
settings. Toggle dithering flag in strategic places and reenable
16bpp drawing cache, to speed up software UI rendering.

Use RGB565 surface for wallpaper

The framebuffer only uses 16bpp on most legacy devices anyway, so this
does not result in worse quality. It saves a lot of GPU fillrate and
memory, though.
