Make avrdude Solaris-compatible.

Browse Source 
* Makefile.am: distclean avrdude.conf.
* avrdude.conf.in: make the parallel-port programmers optional.
* bitbang.c: move the bitbang features out into PROGRAMMER.
* configure.ac: introduce --enable-parport, add Solaris.
* lexer.l: replace str by strng to work around problems in some
versions of flex.
* main.c: move getexitspecs into the respective programmer's
domain; replace rindex by the C-standard strrchr.
* par.c: make parallel port optional.
* par.h: everything but par_initpgm() is private now.
* pgm.h: add setping/getping/highpulsepin/getexitspecs.
* serbb_posix.c: generalize bitbang interface; replace
cfmakeraw() by explicit code.
* serbb_win32.c: generalize bitbang interface.
