 Modified Files:
 	src/sys/dev: random.c
 
 Log Message:
 /dev/random: Fix two signal bugs.
 
 1. If a long write to /dev/random is interrupted by a signal, it may
    proceed to sleep on the entropy source lock instead of returning
    promptly.
 
    => Don't try to consolidate entropy if we've already been
       interrupted by a signal.
 
 2. If a write to /dev/random is interrupted by a signal while
    sleeping on the entropy source lock, it may fail to report EINTR.
 
    => Pass through EINTR from entropy consolidation via new
       entropy_consolidate_sig function.
