There are three changes here that should help reduce the
amount of duration test failures caused by clock skew.
First, we reported some skew when the test expected playback
to start immediately after loading the license. However,
with round-off, this could easily be more than 1 second. So
this does not warrent even a warning.
Second, the fake and real clocks were only synced after
computing how long to sleep. This is fixed by moving
SleepUntil to the TestSleep class and having it sync before
computing the delta and after doing the sleep.
Third, I am guessing that some failures due to unexpected
lenience were caused by the rental or playback clock being
started at the end of signing the license or the end of the
first decrypt instead of the beginning. We work around this
by recording how long these operations take, and then adding
this extra time at the end of the check for FailDecrypt.

When we run a test with the fake clock, the clock had been initialized
to the current time, or to 0. This causes a problem for reboot tests
because the clock might go backwards over the reboot. With this
change, we monitor the clock at the end of one reboot pass and
initialize the clock for the next pass based on the previous value.

clock_settime isn't available on iOS (even though settimeofday is). But
we can't change the system time on iOS anyway, so this just disallows
iOS.

The Widevine License Agreement has been renamed to use inclusive
language. This covers files in the cdm, linux, platform, util directory
in addition to some other files.

This code is based on a bug report and patch from Sony.
The TimeRollbackPrevention test was failing when run with CE CDM and the
OEC Ref, although it passed in some other configurations. The cause was
twofold:
1) The test sleep code was not accounting for rollback when calculating
the clock drift, causing incorrect time values to elapse.
2) Fixing the previous exposed a bug in the CE CDM test host where it
did not handle negative time passing correctly.
This patch expands Sony's fix with additional comments and some code
cleanup to try to make the code clearer and more robust against future
errors, particularly in the error-prone TestHost code.

The unit test TimeRollbackPrevention was broken for several
reasons. This CL reduces the test to its most basic functionality and
updates it to be compatible with a v16 oemcrypto.
This CL also adjusts the fake clock used by the buildbot to fake
sleeping backwards, so that the TimeRollbackPrevention test can also
be run on the buildbot.
