2ad5be846b Fix powerpc/161045. ams_poll() needs to return that any data is available, not
just a new packet.

b700662b06 Restore binary compatibility for GIO_KEYMAP and PIO_KEYMAP.
Back in 2009 I changed the ABI of the GIO_KEYMAP and PIO_KEYMAP ioctls
to support wide characters. I created a patch to add ABI compatibility
for the old calls, but I didn't get any feedback to that.

It seems now people are upgrading from 8 to 9 they experience this
issue, so add it anyway.

7f42e47a67 Make the newbus subsystem Giant free by adding the new newbus sxlock.
The newbus lock is responsible for protecting newbus internIal structures,
device states and devclass flags. It is necessary to hold it when all
such datas are accessed. For the other operations, softc locking should
ensure enough protection to avoid races.

Newbus lock is automatically held when virtual operations on the device
and bus are invoked when loading the driver or when the suspend/resume
take place. For other 'spourious' operations trying to access/modify
the newbus topology, newbus lock needs to be automatically acquired and
dropped.

For the moment Giant is also acquired in some key point (modules subsystem)
in order to avoid problems before the 8.0 release as module handlers could
make assumptions about it. This Giant locking should go just after
the release happens.

Please keep in mind that the public interface can be expanded in order
to provide more support, if there are really necessities at some point
and also some bugs could arise as long as the patch needs a bit of
further testing.

Bump __FreeBSD_version in order to reflect the newbus lock introduction.

db7ede5c50 Make adb_mouse use dev2unit() instead of minor().
A real fix would be to migrate it to si_drv0 to store the softc
directly, but this is the quickest way to fix it right now.

e7517d6bb2 Improve the AT keyboard emulation of the ADB keyboard driver, by supporting
an AT-like K_RAW mode instead of just K_CODE. This has the effect of making
the arrow keys on ADB keyboards work in X11.

e6bc656165 Fix some nasty race conditions in the VIA-CUDA driver that ended up preventing
my right mouse button and keyboard LEDs from working due to mangled
configuration packets. Fixed several other races and associated problems in the
main ADB stack that were exposed while fixing this.

174894b615 Probe ADB miscellaneous devices (ID 7) instead of stopping at ID 6. This
allows us to probe the brightness and volume control buttons on PPC Apple
laptops, though there is not yet a driver to do anything useful with them.

8df5c9ee67 Make the touch pad on my PowerBook G4 12" a little more usable.
For an unknown reason the touch pad of my PowerBook generates button 5
events when you operate it. This causes the adb_mouse code to convert
them to button 2 events, which is not what we want.

Add a new flag, AMS_TOUCHPAD, which is used to distinguish the touch
pad. When set, don't convert button events of unknown buttons to the
last button.

There are still three problems left with respect to user input:

- The mouse button events are not properly processed when the touch pad
  isn't touched.

- The arrow keys on the keyboard don't work inside X11.

- The power button isn't handled by the kernel, similar to the ACPI
  power button on i386/amd64.

ec4658731c Allow a read() on /dev/ams[0-9] to be interrupted.
Right now ams_read() uses cv_wait() to wait for new data to arrive on
the mouse device. This means that when you run `cat /dev/ams0', it
cannot be interrupted directly. After you press ^C, you first need to
move the mouse before cat will quit. Make this function use
cv_wait_sig(), which allows it to be interrupted directly.

5c55d9c1df Fix some possible infinite loops in the ADB code, and remove some hacks
that were inserted in desperation during bring-up. In addition, move ADB bus
enumeration and child attachment to when interrupts are available.

00912a1e64 Add ADB support. This provides support for the external ADB bus on the PowerMac
G3 as well as the internal ADB keyboard and mice in PowerBooks and iBooks. This
also brings in Mac GPIO support, for which we should eventually have a better
interface.
