all of proc.*.

Add an initializer for them: KSI_INIT_EMPTY
Add a predicate for them: KSI_EMPTY_P
Don't bother storing empty ksiginfo_t's since they have no information.
Change uses of KSI_INIT to KSI_INIT_EMPTY where no other information other

Call kcont_init() from init_main before device autoconfiguration,
so kcont is availble to device drivers if required.
Also ensure the kthread process runs any pending continuations once
the kthread is finally up and running. For now, use a non-null timeout
to poll the queue periodically. Draining any pending requests just
before the kthread enters its ltsleep()/kc_run loop is cleaner, but
this is the version I tested with an early-in-boot kcont request.)
- Fix a 32-bit overflow that could erroneously return true even if the
currently allocated buffer memory was greater than the high water mark.
- Add an early check for bufmem > hiwater to avoid a needless call to
random().
- Sprinkle some comments.
Add a vm.bufmem sysctl so the current bufmem value can be easily queried
from userland.

This way, individual ports can circumvent sigcode mapping
by setting sigcode/esigcode.
