DEBUG_GIO allows users to set any GIO options (direction, output state). As this feature should be used only by experienced users it is compiled conditionally.
Raise I2C delay values since udelay() is now precise and previous values seems to be too low for some devices.

On this player EMIF is needed for accessing NOR flash. Disabling it improves battery runtime by about 25 minutes.

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.

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.

* 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 should prevent buffer underruns that can occur during heavy use of buttons or scrollwheel.

Use the battery capacity percents reported by AVR. Internally fake linear voltage scale is used (1 mV = 1%).

The buflib memory allocator is handle based and can free and
compact, move or resize memory on demand. This allows to effeciently
allocate memory dynamically without an MMU, by avoiding fragmentation
through memory compaction.
This patch adds the buflib library to the core, along with
convinience wrappers to omit the context parameter. Compaction is
not yet enabled, but will be in a later patch. Therefore, this acts as a
replacement for buffer_alloc/buffer_get_buffer() with the benifit of a debug
menu.
See buflib.h for some API documentation.
