Conversion to clock_ymdhms wasn't complete: the match routine was calling

Conversion to clock_ymdhms wasn't complete: the match routine was calling
ugettod() with a NULL pointer to test if the clock was present. That
argument was changed to a struct clock_ymdhms pointer and is no longer
optional. Change to pass the address of a local structure when probing
for the clock.

Convert a2kbbc and a3kbbc to newer clock_ymdhms convenience routines in
kern_todr.

Correct some error returns for gettod() and settod() left over from the
pre-todr code, and use actual E* return codes for any error return.

Switch amiga to MI todr.

fixing typo in comment

merge ktrace-lwp.

Fix a ton of const/volatile issues shown with new warning flags

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22364, verified by myself.

Use CFATTACH_DECL().

Declare all cfattach structures const.

add __KERNEL_RCSID as suggested by Luke Mewburn

- ANSIfy
- remove some trailing spaces/tabs
- minor style nits

Kill a couple of unnecessary cf_unit (ab)uses.

Fix comment. No code change.

The Ricoh chip has a seperate leapyear counter.
We must write this when we write the year register, keeping them in sync.
XXX the chosen algorithm only works for 1901 <= year <= 2099.

Write part of the y2k fix.
This is not strictly necessary, as
- at least for the Ricoh chip in the A3000 and A4000, as those chips' Y10
registers happily continue to count up from 0xA if manually incremented
past 0x9.
- the Amiga ROMs and "setclock" commands seem to interpret 0xA 0x? like
200?, etc.

However,
- the Amiga setclock writes the modulo 10 value into the chips
- the chip docs of both chips, including the Y2K information of their
manufacturers, only refer to the range 0-9
- the chips increment from 9 to 0

So we better conform to this, to avoid unpleasant surprises.

*sigh*
Y2000-patch for A2000, A3000 and A4000 battery backed clock modules,
mostly by Adam Ciarcinski.

Use the 1/256s-resolution when reading the DraCo battery backed clock

Adjust for changes to config.

Make Amiga battery clocks autoconfiguration devices, so that they can be
left out of specialized configurations.
