7a12399b39 Allow choosing 115200bps as the card allows it 
Of course, that won't work full speed with the
standard IRQ-based RX. But that will allow users
to setup the port at this speed without duplicating
the setup part of the code. Up to them to add hooks
to disable IRQs and read directly in a tight asm
loop.

b04d79b1da [SIM65] Support undocumented opcodes for 6502 
This PR is mostly a complete rewrite of the emulator for 6502/65c02 opcodes.
It provides an easier to maintain implementation of the instructions, by using few macros rather than having hand-written code for each function.
All undocumented, previously missing opcodes for 6502 are also implemented.
The patch also includes a detailed documentation of those opcodes, for reference to developers.
This PR should fix one of the milestones listed here for the next version of CC65:

1093d169ad Fix BSS obliteration by mliparam during exec(). 
Using mliparam at this time could lead to corruption at the
start of the new executed program if BSS is real full and
mliparam is over $BB00.
The fix is to open the file from the loader stub instead of doing
it before the C library shutdown.

38f7daf40e Make sure not to load ACIA driver on IIgs' Z8530 
The Pascal Firmware Protocol Bytes ID are not enough to differentiate an SSC card from a IIgs serial firmware:
http://www.1000bit.it/support/manuali/apple/technotes/misc/tn.misc.08.html

Loading a2(e).ssc.ser on a IIgs succeeds, then goes to limbo when one tries to use the serial port.

Check first byte on the slot's firmware in addition to the four existing ones, as it's supposed to be $2C (BIT instruction) on an SSC card, and $EF (65C816 SEP instruction) on the IIgs' serial firmware (ROM revisions 0, 1, 3).
