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: 1.30.6;
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.

Remove Token Ring support.

branches: 1.27.6;
Add drvctl to kernel which has audio device.
audiocfg(1) requires drvctl(4).

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

remove the 'wd* at umass?' for the non-standardized and rare (extinct?)
In-System Design ATA protocol over Bulk-Only devices from most kernels,
leave only in i386/amd64 ALL; it's unmaintained and likely currently broken,
lack of test hardware makes it impossible to support

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

branches: 1.23.8; 1.23.10;
rename u3ginit driver to umodeswitch

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: 1.19.2;
Disable uscanner in all kernel configs

As discussed on current-users@, SANE uses ugen via libusb and not
uscanner, so users are not well served by having uscanner. Consensus
is that addressing how to adjust permissions for scanners should not
block restoring basic functionionality.

(Compile-tested only, but there are multiple reports of this being the
right approach.)

branches: 1.18.2;
Fix builds.

branches: 1.17.2;
Rename RT2500USB driver to ural(4) as it was originally in OpenBSD,
as ural(4) and ral(4) do not actually share any code.

Enable ural(4) in hpcarm WZERO3 kernel too, as it will now build.

Fixes PR#43520.

branches: 1.16.2;
Enable or note aubtfwl(4) wherever ubt(4) is enabled or noted.

Add audio for uaudio

add btmagic(4) where other Bluetooth drivers are listed

branches: 1.13.2;
Assorted spelling/capitalization fixes from Igor Sobrado in PR kern/22595.
Remove multiple njata.
Add uthum, udl, stuirda, uchcom, uberry, u3g, ugensa, uvideo.

add uhso(4) device where appropriate
- follow the lead of other USB driver declarations wrt commented out
- (cross-)build tested all these kernels

branches: 1.11.2;
unifdef -D UGEN_BULK_RA_WB

Default behaviour unchanged, the feature must still be explicitly
enabled for a ugen fd.

remove esl (KIYOHARA Takashi)

branches: 1.9.14; 1.9.18; 1.9.26; 1.9.28;
Add bcsp(4).

branches: 1.8.2;
Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

branches: 1.7.2;
Add some devices for Bluetooth, CardBus, PCMCIA, USB.
Remove white-spaces.

branches: 1.6.6; 1.6.10; 1.6.14;
It doesn't make sense to specify "configuration" and "interface"
locators for uhub because a hub can't have sub-devices.
This might be sanity-checked eventually.
Same for ubt now after the change to device attachment.

branches: 1.5.4; 1.5.8; 1.5.10;
Use ATA timing, instead of busmaster wait, for adding waits.
Use default wait value 0x01.

Add njata* at cardbus?
