Submitted by John Voltz: add AVR053 oscillator calibration.

Browse Source 
* main.c: Add the -O option.
* pgm.c: Add the hook for the perform_osccal() method.
* pgm.h: (Ditto.)
* stk500v2.c: Implement perform_osccal().
* avrdude.1: Document the -O option.
* doc/avrdude.texi: (Ditto.)
Partially closes bug #17487: AVR RC oscillator calibration
routine not supported (feature request)
