[CBM] More clean-ups: * added c128 swedish/finnish confirmed dump (thanks to Iggy Drougge) * added c128d/81 (c128d proto with 1581 built-in drive) * fixed TPI6525 regression in c16 emulated floppy * added back floppy timer to c16 floppy reading code * (slightly) improved head positioning and byte reading in floppy emulation * enabled floppy emulation in sx64, c16v, vic20v (emulation does not work yet, but it does not crash anymore MESS either) * added floppy drive firmware dumps for 1540, 1541, 1551, 1570, 1571, 1581, 2031 drives (see notes in vc1541.c) * enabled floppy emulation in c16c, c128d, c128dcr, c128d81 (not working as sx64, but needed to document firmwares)

	114	+ preliminary vc1541 & c1551 implementation (quite slow, especially
	115	if you turn on logging)
115	116	+ no support for other drive types (even if now I list all

117	118	+ communications between the drive CPU and the computer CPU have
118		to be checked, debugged and improved
	119	to be checked, debugged and improved: somehow it works, but no
	120	sync bit is set (encoding bug? timers-related bug?) and the drive
	121	keeps reading beyond the end of the track (synchronization
	122	problems?)
119	123	+ all but .g64 images should be correctly encoded at loading time
120	124	(I actually have doubts about some .d82 details)
121	125	+ error maps are not still used, even if their presence is
122	126	acknowledged
123		+ the floppy handling still uses CBM_Drive_Emu struct instead of
124		functions similar to other floppy formats
	127	+ floppy drives should become devices and use ROMREGION_LOADBYNAME
	128	for their ROMs (not the current defines)
	129	+ all available drive dumps are included for each systems using it
	130	(vc1541 = sx64, vip64, c16v, plus4v; vc1571 = c128d; vc1571cr = c128dcr;

	132	c1551 = c16c, plus4c). this is only a temporary workaround to document
	133	available dumps. correct revisions will be used with each systems when

1126	1191
	1192	* There is no 6526 or 8521 in the drive section of the 128DCR. I believe the
	1193	5710 handles fast serial because the 5710 is a Commodore custom chip and
	1194	128 fast serial is a Commodore custom protocol. [Ed's note: Commodore lists
	1195	NTE229, ECG229, SK3246A/229, and 121-Z9021 as substitutes of the 5710.]
	1196
	1197	* There is no 177x or heat-shrink-wrapped daughterboard in the drive section
	1198	of the 128DCR. I believe the Motorola plastic quad flat-pack chip handles
	1199	MFM because I am pretty sure that I have seen this chip in IBM PC drive
	1200	mechanisms.
	1201
	1202	* The 1571cr ROM works great in 1541 mode but not at all in 1571 mode in a
	1203	standalone 1571.
	1204
	1205	* Olaf Seibert informed me that the 1571cr ROM contains a string to the
