Clear knotes when finishing wseventvar

When finishing a wseventvar in wsevent_fini(), clear the klist.
Otherwise knotes can be left dangling, which can crash the kernel.

In general, klist_invalidate() should happen after vdevgone() in order
to avoid a race with kevent registration. However, the current wscons
drivers clear the wsevent pointer (sc->sc_base.me_evp) before calling
wsevent_fini(). This prevents the drivers from registering new kevents.

Refactor klist insertion and removal

Rename klist_{insert,remove}() to klist_{insert,remove}_locked().
These functions assume that the caller has locked the klist. The current
state of locking remains intact because the kernel lock is still used
with all klists.

Add new functions klist_insert() and klist_remove() that lock the klist
internally. This allows some code simplification.

A wscons device may only be opened in read/write mode once. However,
after checking for exclusive access, malloc() can sleep in
wsevent_init() opening up for a potential race where more than one

Utilize sigio with wscons. The old behavior of always making the process group
of the process who opens the device the default recipient of sigio is removed as
a side-effect of this change. Issuing ioctl(FIOSETOWN) is therefore mandatory in
order to receive sigio, which is more consistent with other subsystems
supporting sigio.

This change is all made possible by the new sigio(9) API and prevents wscons
from keeping a pointer to the recipient process. Usage of such pointer could
cause a panic since wscons is not inform on process deallocation, leaving a
dangling pointer behind.

A wscons device may only be opened in read/write mode once. However,
after checking for exclusive access, malloc() can sleep in
wsevent_init() opening up for a potential race where more than one
thread may be able open the device. Prevent this by checking if the race
was won after calling malloc().

While here, switch to mallocarray as proposed by both cheloha@ and mpi@

Utilize sigio with wscons. The old behavior of always making the process group
of the process who opens the device the default recipient of sigio is removed as
a side-effect of this change. Issuing ioctl(FIOSETOWN) is therefore mandatory in
order to receive sigio, which is more consistent with other subsystems
supporting sigio.

This change is all made possible by the new sigio(9) API and prevents wscons
from keeping a pointer to the recipient process. Usage of such pointer could
cause a panic since wscons is not inform on process deallocation, leaving a
dangling pointer behind.

First step towards making uiomove() take a size_t size argument:
- rename uiomove() to uiomovei() and update all its users.
- introduce uiomove(), which is similar to uiomovei() but with a size_t.
- rewrite uiomovei() as an uiomove() wrapper.
