This option allows accessing the card slot from "dumb" USB hosts like some car
audio systems that do not handle multi-LUN devices.

- now identity map dram uncached and have a cached and buffered virtual alias
- rework dma to handle virtual to physical pointers conversion
- fix lcd frame pointer
- implement usb detection properly
- implement bootloader usb properly
- allow the bootloader to disable MMC windowing (useful for recovery)

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.

buffer chunks.
* Samples and position indication is closely associated with audio data
instead of compensating by a latency constant. Alleviates problems with
using the elapsed as a track indicator where it could be off by several
steps.
* Timing is accurate throughout track even if resampling for pitch shift,
whereas before it updated during transition latency at the normal 1:1 rate.
* Simpler PCM buffer with a constant chunk size, no linked lists.
In converting crossfade, a minor change was made to not change the WPS until
the fade-in of the incoming track, whereas before it would change upon the
start of the fade-out of the outgoing track possibly having the WPS change
with far too much lead time.
Codec changes are to set elapsed times *before* writing next PCM frame because
time and position data last set are saved in the next committed PCM chunk.

The buffer_offset paramter of audio_init_recording() is removed as it
was unused in both implementations.

Namely, introduce buffer_get_buffer() and buffer_release_buffer().
buffer_get_buffer() aquires all available and grabs a lock, attempting to
call buffer_alloc() or buffer_get_buffer() while this lock is locked will cause
a panicf() (doesn't actually happen, but is for debugging purpose).
buffer_release_buffer() unlocks that lock and can additionally increment the
audiobuf buffer to make an allocation. Pass 0 to only unlock if buffer was
used temporarily only.
buffer_available() is a replacement function to query audiobuflen, i.e. what's
left in the buffer.
Buffer init is moved up in the init chain and handles ipodvideo64mb internally.
Further changes happened to mp3data.c and talk.c as to not call the above API
functions, but get the buffer from callers. The caller is the audio system
which has the buffer lock while mp3data.c and talk mess with the buffer.
mpeg.c now implements some buffer related functions of playback.h, especially
audio_get_buffer(), allowing to reduce #ifdef hell a tiny bit.
audiobuf and audiobufend are local to buffer.c now.

The previous maximum (20) still causes excessive heat for some people, and measurements (using a digital camera and a white screen) show that the maximum brightness in the OF corresponds to 12 in rockbox, so we use 12 now.

Also set up a callback for the battery capacity setting (for all players) so changes take effect without having to reboot.

Listen to headphone plug events. There are currently two glitches with this:
- Android takes a while until it reports the unplug event, so there will be
some delay until playback gets paused. This is an Android limitation.
- Rockbox debounces headphone state changes for one second. Therefore playback
will shortly be routed to the speaker on unplug until Rockbox does the actual
pause.

Codec files are loaded as dynamic libraries. Instead of extracting them from
the packaged libmisc.so and therefore having them present twice on the device
put them into the apk as native libraries. Decreases the size of the installed
Rockbox by the compressed size of the codecs. Also, the extraction on first
Rockbox startup gets notably faster since it's less data to extract.

The NDK includes swap16 and swap32 macros, Rockbox as well. Use the Rockbox
ones and avoid a macro redefined warning.
