bug #34027: avrdude AT90S1200 Problem (part 1 - bitbang

Browse Source 
programmers)
* config_gram.y: Introduce new keyword "is_at90s1200".
* lexer.l: (Ditto.)
* avrdude.conf.in: Applew new keyword to the AT90S1200 device.
* avrpart.h: Introduce new flag AVRPART_IS_AT90S1200, reflecting
the is_at90s1200 configuration keyword.
* bitbang.c (bitbang_initialize): Replace existing test for
AT90S1200 by AVRPART_IS_AT90S1200
* avr.c (avr_write_byte_default): Avoid the pre-write reading for
the AT90S1200, as this appears to sometimes corrupt the high byte
by pre-programming the low byte just written into it.
