Apparently the backlight driver is leaking current even when the PWM set to 0.
This patch should greatly improve the battery life of the device.

With current MinGW using c99 as standard the compiler causes problems with some
types. Use gnu99 standard instead which doesn't do this.

I have a suspicion that if there is any scrolling skin lines when
the buflib buffer moves it will cause the lcd code to crash.
This *hopefully* explains the random skin related crashed which
have been reported.

This tool is a scriptable (lua) tool to patch binaries, it supports:
- raw binary
- ELF
- SB(v1/v2)
It also contains some basic routines to parse and generate useful arm/thumb code
like jump or register load/store. This is very useful to take a firmware and
patch an interrupt vector or some code to jump to an extra payload added to
the binary. Examples are provided for several STMP based target which the payload
is expected to be hwstub, and also for the Sansa View. A typical patcher usually
requires three elements:
- the lua patcher itself
- the payload (hwstub for example)
- (optional) a small stub either to jump properly to the payload or determine
under which circumstance to do the jump (hold a key for example)

On those targets, since the LCDIF cannot recover from underflow, changing the
EMI frequency kills one frame and cause flicker.

* e200v2 shouldn't use 24bit (was just for testing)
* samsung ypr0/ypr1 should enable it but the correct number must be passed to bmp2rb

With LCD driver all calculation will be performed on RGB888 and the hardware/OS
can display from our 24bit framebuffer.
It is not yet as performance optimized as the existing drivers but should be
good enough.The vast number of small changes is due to the fact that
fb_data can be a struct type now, while most of the code expected a scalar type.
lcd-as-memframe ASM code does not work with 24bit currently so the with 24bit
it enforces the generic C code.
All plugins are ported over. Except for rockpaint. It uses so much memory that
it wouldnt fit into the 512k plugin buffer anymore (patches welcome).

An upcoming lcd-24bit.c driver will re-use a lot of code from the 16bit
drivers, so prepare for that.

Invalid event data would be accessed if a play message isn't queued
which will cause crash problems.
It came about in the addition of time-based resume.

There is no simple method to detect radio through the 3-wire interface, so it's
not implemented for the YH-925 for now. YH-920 always has a radio.

Because of architecture of the codec it's always necessary to route the input
signal from ADC to DAC, in order to have a control over the monitoring volume
and in order to hear anything while recording.

* sudoku: make colour icons (without screen was squeezed)
* jewels: add colour bitmaps
* pegbox: make game fit on screen (add small header bitmap),
improve keymap
I left the original pegbox keymaps for samsung's YH-92x,
because they seem to make some sense there (YH92x has a
REC switch instead of pushbutton).
Someone with a YH9xx target has to check what is better...
