* 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.

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.

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%).
