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.
