Log Message:
Register KTR events for debugger related signals

Register signals for:

 - crashes (FPE, SEGV, FPE, ILL, BUS)
 - LWP events
 - CHLD (FORK/VFORK/VFORK_DONE) events -- temporarily disabled
 - EXEC events

While there refactor related functions in order to simplify the code.

Add missing comment documentation for recently added kernel functions.
