Log Message:
Implement debugging feature for pserialize(9)

The debugging feature detects violations of pserialize constraints.
It causes a panic:
- if a context switch happens in a read section, or
- if a sleepable function is called in a read section.

The feature is enabled only if LOCKDEBUG is on.
