Remove ksyms from AGATE/DEBUG configs, it is defined in included default config.
Remove unneeded "channel ?" for atapibus* in DEBUG config.
Add "midi* at midibus?" needed for umidi to compile in DEBUG config.
Change SOFTFLOAT to FPEMUL in std.playstation2 (property was renamed).

playstation2 code was likely never fully restored/fixed and doesn't build, but
these changes would be needed in case someone will.

Remove uscanner(4) driver

This exists for compatibility with a Linux interface which was apparently
deprecated in Linux 2.6. There are various mailing list threads going
back to 2004 where the usefulness of this driver is discussed, but
the conclusion is that scanner software has all moved to using ugen(4)
instead, and enabling this driver will not help you scan things.

branches: 1.27.6;
Remove uyap, USB YAP phone firmware loader.

And the associated ezload EZ-USB code, which is only used by uyap.
It could theoretically be used by other drivers, but none of them are
in tree.

I suspect that this device isn't in use, as phone technology has improved
a lot since 2001 when uyap(4) was added to the tree.

Proposed with no objections on netbsd-users on 13 April 2020

remove urio(4), a driver for the Rio500 MP3 player.

At this point it is highly unlikely this 1999 device still has users,
but it still comes up in the context of maxv's USB-fuzzing (and any device
could pretend to be a urio(4)), so it's best to get rid of it.

Renamed all major entries to obsolete, as was done in previous removals.

This still requires an update to sanitizers, but they're located in
"external", perhaps it should be first committed upstream?

Proposed on tech-kern a month ago.

branches: 1.25.6;
Add ure(4) to kernel config files. Also add PHY drivers where necessary.

Add (commented out) mue(4) to where appropriate.
Also add MII/PHY drivers for USB NICs if missing.

branches: 1.23.14; 1.23.16;
wildcard speaker attachments, now that we can handle many of them.

remove VAUDIOSPEAKER for now, will be done differently.

Add a synthesized pc beeper and keyboard bell for platforms with an audio
device.

branches: 1.20.2;
Add `pseudo-device ksyms' where `options DDB' is used, because
config(1)/config(5) can't handle module dependency correctly at this
moment.

(This is another proof that shared file definition (`file xxx.c a|b')
is a bad idea.)

Remove the KMEMSTATS option. It no longer exists.

branches: 1.18.6; 1.18.8;
Bring back the playstation2 port - now that a toolchain for it is
available again.

branches: 1.17.10; 1.17.16;
Remove support for NetBSD/playstation2.

branches: 1.16.72; 1.16.86;
Fix typo (Prolofic -> Prolific).

Remove 'count' argument for pseudo-devices that ignore it
(vnd, bpfilter, ppp, gif, gre, tun, sl, strip, faith, stf).

branches: 1.14.2; 1.14.4; 1.14.6;
merge ktrace-lwp.

branches: 1.13.2;
Add ukyopon(4).

branches: 1.12.4; 1.12.10;
s/uax/axe/

Add "options SYSCTL_INCLUDE_DESCR" to a lot of configs, but commented
out in most of them.

If a playstation2 kernel config does "options KLOADER_KERNEL_PATH",
it now also needs to do "options KLOADER", ref. the new playstation2
machdep.c, so fix these kernel configs accordingly.

branches: 1.9.2; 1.9.4;
Add uax(4) (and url(4) in some cases).

enable USERCONF by default; it's small and extremely useful to have available.

branches: 1.7.4;
Add the INCLUDE_CONFIG_FILE option to all config files. In config
files that are generic (ie, GENERIC, GENERICSBC, GENERIC32, ALL, or
ALPHA), it is uncommented.

Add commented-out USERCONF option. Mainly useful for install media
and can be optionally enabled based on miniroot and ramdisk size
requirements.

add options PIPE_SOCKETPAIR to individual kernel configs
the option is commented out on everything but kernels I was able
to recognize as INSTALL-like or ones for small memory machines

branches: 1.4.2;
sync with uhidev change.

integrate BUILTIN_KERNEL_LOADER and KERNE_PATH into KLOADER_KERNEL_PATH.

cleanup:
options SPACE TAB
makeoptions TAB
psuedo-device TAB
remove trailing whitespace
replace multiple spaces -> tabs
options "FOO" -> options FOO
options "FOO=bar" -> options FOO=bar
options "FOO=\"bar\"" -> options FOO="\"bar\""

branches: 1.1.4;
