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.

f1b0fbebd5 Remove all indexed accesses to SCC registers 
Some IIgs models had issues sending bytes out.
Also make channel tests clearer.

fe115fb621 Revert "Apple 2 SSC: Handle SER_HS_NONE with no performance impact" 
This reverts commit 0eafb6d1d5.
This was buggy, as we sta Stopped when asserting flow, and this stops
SER_GET.

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).

734541ee05 Serial: Optimize SER_GET 
There is no need to TryToSend before getting the character. We
send bytes during SER_PUT, and if interrupted during sending, we
still try to do it at the beginning of the next SER_PUT.

89af42e5cb Serial: Optimize SER_IRQ 
Apple2 and Atmos have Index in X, but can still use it for the
best-case path as long as we reload it in the worst-case part
(when we assert flow control).
Also, standardize the free space to trigger flow control to 32
characters left (compare with RecvFreeCnt before decrement)
