bootanim: Don't cache textures if they're expected to use a lot of VRAM

bootanimation cached all the textures generated until the animation
was completed.
For Hi-res animations with lots of frames (like the new CM9 anim on
xhdpi devices), this implied using large amounts of video RAM, more
than most devices actually have available, causing the animation to
stall (and in some cases, gralloc to lock up); so if an animation is
expected to use a lot of RAM (rough estimation based on frame size
and number of frames), disable cache entirely and generate the textures
on demand

bootanimation: performance enhancements

This patch implements two simple performance enhancements, which
might benefit devices. They are completely opt-in by setting
the following variables.

  * TARGET_BOOTANIMATION_PRELOAD: will preload the bootanimation
    zip to memory; this is handy on devices where the storage
    might be slow. By preloading it, we get quick access to the
    zip file, and the animation doesn't stutter.

  * TARGET_BOOTANIMATION_TEXTURE_CACHE: allows maintainers to
    force texture cache on/off.

Also fixes the sign warnings related to int / size_t comparison

bootanimation: allow using RGB565 instead of ARGB8888

RGB565 uses considerably less memory, and together with texture
cache, it allows us to offer a really smooth bootanimation on
not so powerful devices.

Smooth Spinners: Makes the loading "spinner" animation smoother in non-holo apps

The loading "spinner" animation is quite jerky by default when the progress xml's from
drawable are called in applications that don't use the holo progress animation. The holo
"spinner" animation is already smooth by default. This makes every other "spinner"
animation smooth.

We've been changing this value in all ROM's we release, both AOSP and CM based ones
as well as stock ROM's, since it gives a more polished look to the entire system. In the past
3 years we've been using this small tweak we have not noticed anything that would
adversely affect battery life or system operations as a whole.

Framework: Add Advanced reboot (2 of 2) By DvTonder

This commit responds to a setting in Development settings for including
options in the power menu for rebooting into recovery or bootloader. It
is defauled to off.

When enabled, the Advanced reboot options will only be available once the
device is unlocked.
