bug #22248: Read efuse error
* avrdude.conf.in (m168, m328, m48, m88, t1634, t26, t261, t461,
t861, t88): In efuse (or hfuse for t26) read operation, turn all
bits in byte 3 from "x" to "o" (output); this is a first step
towards fixing the symptoms mentioned in the bug, by unifying the
behaviour between different AVRs.  Not touched are the historic
devices where the fuses are not documented to form a full byte
each (2333, 4433, 4434, 8535, m103, m161, m163).

ser_posix: added support for faster baudrates than 230400 on posix based systems
butterfly: implemented a variabel timeout for the erase call in the avr109 protocol. Needed to support AVRs with more than 128kB programm memory.
