Most calls to bus_alloc_resource() use "anywhere" as the range, with a given
count. Migrate these to use the new bus_alloc_resource_anywhere() API.

The digi(4) driver directory contains some files that cannot be checked
out on Windows filesystems. This isn't a big deal, but the files aren't
used anyway.
There are still some other places where checkouts on Windows don't work,
such as VFS_MOUNT.9/vfs_mount.9. This should already be a small
improvement.

ioctls passing integer arguments should use the _IOWINT() macro.
This fixes a lot of ioctl's not working on sparc64, most notable
being keyboard/syscons ioctls.
Full ABI compatibility is provided, with the bonus of fixing the
handling of old ioctls on sparc64.

- Add a new function linker_release_module() as a more intuitive complement
to linker_reference_module() that wraps linker_file_unload().
linker_release_module() can either take the module name and version info
passed to linker_reference_module() or it can accept the linker file
object returned by linker_reference_module().

modes on a tty structure.
Both the ".init" and the current settings are initialized allowing
the function to be used both at attach and open time.
The function takes an argument to decide if echoing should be enabled.
Echoing should not be enabled for regular physical serial ports
unless they are consoles, in which case they should be configured
by ttyconsolemode() instead.
Use the new function throughout.

rename ttyopen() -> tty_open() and ttyclose() -> tty_close().
We need the ttyopen() and ttyclose() for the new generic cdevsw

Add a MOD_QUIESCE event for modules. This should return error (EBUSY)
of the module is in use.
MOD_UNLOAD should now only fail if it is impossible (as opposed to
inconvenient) to unload the module. Valid reasons are memory references
into the module which cannot be tracked down and eliminated.
When kldunloading, we abandon if MOD_UNLOAD fails, and if -force is
not given, MOD_QUIESCE failing will also prevent the unload.
For backwards compatibility, we treat EOPNOTSUPP from MOD_QUIESCE as
success.
Document that modules should return EOPNOTSUPP for unknown events.

Introduce d_version field in struct cdevsw, this must always be

completenss. The pessimization is tiny compared with i/o port slowness
except on very old machines, but code that used signed short types for
i/o ports was unpessimized long ago, and the macro that detected it
recently started working for u_short types too. Use of bus space
should have made this moot long ago.
