This improves battery runtime on Sansa Connect by approximately 40 minutes.

This improves framerate update (when uboosted, approximate values) from 151 fps to 911 fps for whole screen update and from 432 fps to 3017 fps for quarter screen update.

Nick some aspects from the as3525 ascodec driver to improve throughput in
the beast's SPI communications by switching tranfer descriptors to the
caller's stack and getting rid of thread synchronization.
Fix a bug that suddenly became obvious that could permanently stall the SPI
driver because all data could be shifted out before the interrupt could get
serviced. In that case, it needs a kick to restart it. Should probably put
the SPI interrupt priority above DVFS.
A tweak to the event registration interface to simplify it.

This adds wildcards to accept section names created by -ffunction-sections
and -fdata-sections. It should now be possible to build all targets with
those switches. Other wildcards such as those in r31337 and r31338 are only
needed when things are explicitly put into those sectons.

Vectors are needed by the CPU, but they don't need to be accessed by Rockbox.
Without the KEEP(), they can be removed when liking with --gc-sections,
creating a broken binary without any warnings. This tells the linker to not
remove them. It should enable use of --gc-sections for all targets. When not
using --gc-sections, this does not change the binary.

When a global pointer is not declared as constant, gcc will put it in
memory. Getting the address of the string it points to requires loading
the address of the pointer and then loading the pointer. When the pointer
is declared constant, the address of the string is loaded directly.

* Add wildcards to various sections placements a la *(".text") => "*(.text*)"
* Remove hacky bits from those linker scripts (no problem encountered testing)
* Change section for asm functions from .<section> to .<section>.<function>
so that -ffunction-sections works for those asm file too.

Massage the way it interfaces a bit to make things more flexible.
The chroma_buf scheme on Sansa Connect and Creative ZVx calling the
lcd_write_yuv420_lines implementation in lcd-as-memframe.S with five params
with a chroma buffer that the function can't use wouldn't work anyway so just
have them use the stock implementation (really, how was that working?).

This only works for Windows, so you need to use it on Windows or set CROSS
accordingly.

There is no need to always build sansapatcher with embedded bootloaders. Allow
building without similar to ipodpatcher. Interactive mode will obviously not be
available if built without bootloaders.
Fix rules for creating the source files for the embedded bootloaders.

This allows building libipodpatcher, which will make it possible to stop
building ipodpatcher files in Rockbox Utility directly. Move some OS X common
values to libtools.make as well (might fix building libmkamsboot on OS X).

Without an RTC, Rockbox doesn't keep time. In that situation, USB time sync
previously did nothing but reported success. After this change, the USB time
sync request won't be recognized on those targets.

For this commit: Sansa e200v1, Gigabeat F, Gigabeat S and Mini2440 are
changed over. Quite a number of other targets probably can be as well.
General LCD code is moved out of the target drivers into
drivers/lcd-memframe.c.
