Apple II: Document BLTU alternative

Fix RANGE ERROR STOPPED AT 8214
...
On a 48k Apple II, the BLTU2 call throws an error,
even when there is nothing to copy in the LC segment.
Add an alternative LC copy, based on memcpy, to an
extra file that the user can link in as with iobuf-0800.
This memcpy-based version allows our programs to run on
Integer ROM apple2. It costs 21 bytes in binary size,
plus memcpy (60 bytes in binary size + RAM use) if it
wasn't already linked in.

Avoid enabling IRQ after disabling them in driver code, remember

IIgs SCC: 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.

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.

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).
