Add libasound.so and conf files to prebuilts

These don't really belong with the vendor blobs -- they're built from
source (and in fact, the copies being committed are built directly from
a CM 10 source tree -- they're prebuilt for now to avoid having to
re-add external/alsa-lib to the CyanogenMod project).
proprietary-files.txt: remove libasound.so and other audio cruft

This stuff is either unnecessary or now residing in device/bn/encore.

Lock the CPU clock speed to 1 GHz as early as possible

This reduces the amount of time the CPU is running at higher clock
speeds during early boot.

Add a new power HAL

This very simple power HAL pins the L3 (memory) bus clock speed to the
max only while the screen is on, allowing us to benefit from improved
graphics performance without using power unnecessarily while the screen
is off.

SurfaceFlinger: use HAS_CONTEXT_PRIORITY

The OMAP3 SGX530 EGL driver has this extension, and it appears to help
performance, so use it.

KXTF9 HAL: close file descriptors when we're done with them

The failure to do so was leaking file descriptors, eventually causing
all of userspace to fall over with EMFILE errors.  Thanks to XDA user
webyrd for reporting.

Add a new powervr.ini to configure the screen refresh rate

We need to configure the screen refresh rate in order to get optimum
performance without tearing from the graphics subsystem.

While we're at it, remove this file from proprietary-files.txt -- it's
not a binary blob, so it doesn't belong there.

Update ro.vold.switchablepair for new storage locations

Thanks to XDA user leapinlar for noticing these were out of date.
