Scrollstrip works as quadrature encoder. We set pin change
interrupt for both edges of signal both lines and sample the state
in ISR. From time to time the sequence is out-of-sync which was
properly detected but erroneously handled leaving scrollstip
interrupts disabled.

Before, the Cypress chip power is always turn on either from internal battery
or from usb host. In this regard, the internal battery energy was spend on the
inactive chip. Now power of the Cypress chip is enabled only on the external usb host.

The only true difference in this platform is the amount of iram
between MCF5249 and MCF5250. Instead of duplicating the file
simply use one with proper ifdefs.

Additional status callback is added to pcm_play/rec_data instead of
using a special function to set it. Status includes DMA error
reporting to the status callback. Playback and recording callback
become more alike except playback uses "const void **addr" (because
the data should not be altered) and recording uses "void **addr".
"const" is put in place throughout where appropriate.
Most changes are fairly trivial. One that should be checked in
particular because it isn't so much is telechips, if anyone cares to
bother. PP5002 is not so trivial either but that tested as working.

Change all lcd drivers to using a pointer to the static framebuffer
instead of directly accessing the static array. This will let us
later do fun things like dynamic framebuffer sizes (RaaA) or
ability to use different buffers for different layers (dynamic
skin backdrops!)

Scrollstrip (as well as scrollwheel on ipods/sansas) works like
quadrature encoder. The states of input lines are tracked by the
gpio ISR and when the sequence is correct, appropriate button
event is pushed to the button queue directly. The downside of
this implementation is that scrollstrip doesn't emit _REL
events which has some weird consequences. For the scrollwheels
some hack have been crafted in action system to accomodate for
this. I don't like this approach. IMO the correct fix is to
properly emit _REL event when the user stops interacting with
the device or reverses the direction of the move. This patch
implements timeout which forces to emit _REL when expired.

This dir is suitable for stuff that doesn't fit the target tree, e.g. because
it also builds on hosted or otherwise. It also has a generic subfolder for
fallback C implementations so that not all archs need to provide asm files.
SOURCES should only contain "foo.c" where foo.c includes the specific
<arch>/foo.c files from the subdirs using the preprocessor. This way automatic
selection of asm versions or generic C verion is possible.
For the start, the thread support files are moved, since ASM threads can
be used on hosted platforms as well. Since core_sleep() remains platform
specific it's moved to the corresponding system.h headers.

* Introduce CONFIG_BATTERY_MEASURE define, to allow targets (application)
to break powermgmt.c's assumption about the ability to read battery voltage.
There's now additionally percentage (android) and remaining time measure
(maemo). No measure at all also works (sdl app). If voltage can't be measured,
then battery_level() is king and it'll be used for power_history and runtime
estimation.
* Implement target's API in the simulator, i.e. _battery_voltage(), so it
doesn't need to implement it's own powermgmt.c and other stubs. Now
the sim behaves much more like a native target, although it still
changes the simulated battery voltage quickly,
* Other changes include include renaming battery_adc_voltage() to
_battery_voltage(), for consistency with the new target functions and
making some of the apps code aware that voltage and runtime estimation
is not always available.

In order to enable it, #define HAVE_DUALBOOT when building the bootloader.
Do not use the automatically created x5_fw.bin or m5_fw.bin, but use mkboot
to create a new firmware file from an OF x5_fw.bin resp. m5_fw.bin and
bootloader.bin.
The dual-boot bootloader boots the OF when pressing Play (main or remote) for
more than 3 seconds. Hold it a bit longer because the OF also checks buttons.
Short press boots rockbox.
As a bonus, the Play button read (for hold check) is done a bit earlier for
single-boot mode as well.
