Robert Watson 5ee847d3ac Reimplement and/or implement vnet list locking by replacing a mostly
unused custom mutex/condvar-based sleep locks with two locks: an
rwlock (for non-sleeping use) and sxlock (for sleeping use).  Either
acquired for read is sufficient to stabilize the vnet list, but both
must be acquired for write to modify the list.

Replace previous no-op read locking macros, used in various places
in the stack, with actual locking to prevent race conditions.  Callers
must declare when they may perform unbounded sleeps or not when
selecting how to lock.

Refactor vnet sysinits so that the vnet list and locks are initialized
before kernel modules are linked, as the kernel linker will use them
for modules loaded by the boot loader.

Update various consumers of these KPIs based on whether they may sleep
or not.
