Change the kqueue filterops::f_isfd field to filterops::f_flags, and
define a flag FILTEROP_ISFD that has the meaning of the prior f_isfd.
Field and flag name aligned with OpenBSD.

This does not constitute a functional or ABI change, as the field location
and size, and the value placed in that field, are the same as the previous
code, but we're bumping __NetBSD_Version__ so 3rd-party module source code
can adapt, as needed.

Add d_discard to all struct cdevsw instances I could find.

Change (mostly mechanically) every cdevsw/bdevsw I can find to use

I have not built every extant kernel so I have probably broken at
least one build; however I've also found and fixed some wrong
cdevsw/bdevsw entries so even if so I think we come out ahead.

remove diagnostic printfs to make this compile again.

Remove code from dev/apm/apm.c for setting global variables to parameterise
the i386 bios apm code (now removed).
Remove the same code from the clone dev/hpc/apm/apmdev.c
Remove some not-used options from dev/apm/files.apm and the commented out
lines in ALL and GENERIC.
Maybe the APM_V10_ONLY and APM_NO_V12 could also be shot, but they are
further entwined in the code.

Retire varargs.h support. Move machine/stdarg.h logic into MI
sys/stdarg.h and expect compiler to provide proper builtins, defaulting
to the GCC interface. lint still has a special fallback.
Reduce abuse of _BSD_VA_LIST_ by defining __va_list by default and
derive va_list as required by standards.

Remove some unecessary includes sys/user.h header.

Use dev/apm/files.apm for APM options in opt_apm.h.

Now both apm and apmdev files.apm can be included so you can switch
from apmdev0 to apm0 at hpcapm0 in your kernel config easily.

Switch apmdev to use apm(4) structures from dev/apm/apmvar.h.
Add batteryid argument to aa_get_powstat method implementations.

Further reduce diffs to dev/apm/apm.c.

Bring over remaining bits of logic not picked up in the first round.
Main semantic difference between the two that ramins is now basically
powerhooks vs. pmf.

Cosmetics to reduce diff noise: split apmattach into apmdevattach and
apm_attach, where the latter matches its counterpart in the real
apm.c. Change local macros names from APMDEV* to APM*

Now that apmdev.c is demonstrably congruent to apm.c it should be
easier to switch hpc* and zaurus ports to apm.c from apmdev.c.
apmdev.c is one of the only two remaining drivers that call
dopowerhooks(9), the other one being arch/arm/xscale/pxa2x0_apm.c.

Ideally I would prefer for them to be interchangeable to smooth the
transition (in pmf world order *all* devices must have pmf hooks
registered), but they are attached differently - apmdev is separate
from its backend device (like hpcapm), while apm.c backends are
attachment glue, not separate devices.

Split device_t and softc, use aprint_*, rename/reformat stuff to
minimize diffs to dev/apm/apm.c (even at the cost of uglification).

Welcome to 4.99.55:

- Add a lot of missing selinit() and seldestroy() calls.

- Merge selwakeup() and selnotify() calls into a single selnotify().

- Add an additional 'events' argument to selnotify() call. It will
indicate which event (POLL_IN, POLL_OUT, etc) happen. If unknown,
zero may be used.

Note: please pass appropriate value of 'events' where possible.
