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.
