Revert r330897:

This was intended to be a non-functional change. It wasn't. The commit
message was thus wrong. In addition it broke arm, and merged crypto
related code.

Revert with prejudice.

This revert skips files touched in r316370 since that commit was since
MFCed. This revert also skips files that require $FreeBSD$ property
changes.

Thank you to those who helped me get out of this mess including but not
limited to gonzo, kevans, rgrimes.

Use clock_gettime(CLOCK_SECOND) instead of gettimeofday(2) for
implementation of time(3). CLOCK_SECOND is much faster.

C99 compliance: time() always sets its return value in both places
(if present), even on error.
