patch #4539: Ability to control the bit clock (usleep) delay
for ppi interface
* bitbang.c: Implement bitbang_delay() and its calibration.
* bitbang.h: Declare bitbang_delay().
* main.c: Add the ispdelay option (-i).
* pgm.h (struct programmer_t): Add the ispdelay parameter.
* par.c: Add calls to bitbang_delay() when requested.
* serbb_posix.c: (Ditto.)
* serbb_win32.c: (Ditto.)
* avrdude.1: Document the new -i option.
* doc/avrdude.texi: (Ditto.)
