b23a7ec407 Save two bytes in pushax and popptr1 
It's not because Y must equal zero on rts that we should'nt spare one byte
and one cycle.

df193c0947 Rework time functions a bit 
- mktime: Work unsigned as time_t's type implies (shifting Y2K38 bug to 2106)
- mktime: Add unit tests
- gmtime/localtime: factorize
- gmtime/localtime: Add unit tests
- mktime/gmtime/localtime: Size optimisation (-130 bytes wrt master)
- mktime: Speed optimisation (from 23M cycles on the unit test to 2M)

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.

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).
