XPM USART Screendump functions

This service will add the possibility to dump the LCD screen to the USART using the XPM file format.

Before using the screen dump function one should make sure that one has performed initialization of this service by calling gfx_mono_screen_dump_init() to set up which USART to use. One should also make sure that one has initialized the gfx mono driver gfx_mono_init() which will produce the screen buffer that is dumped trough the USART.

This driver depends on the following modules:
