ser_posix.c files.
* avr910.c: New file (stubs for avr910 serial programmer).
* avr910.h: New file.
* ser_posix.c: New file.
* ser_win32.c: New file (just stubs for now).
* serial.h: New file.
* stk500.c: Move all the code for accessing the posix serial ports
into ser_posix. This will make a native win32 port easier and allows
the avr910 programmer to share the serial code.
