c6bee8e4b2 Fix integer overflows in QDeadlineTimer
If the deadline is far in the future, the conversions to nanoseconds
or internal arithmetic may overflow and give an invalid object, thus
the deadline may end up in the past. Added a test to the testlib
selftest for sleep.

[ChangeLog][QtCore][QDeadlineTimer] Fixed integer overflows
leading to immediate timeouts.

6ec86513dd Increase the resolution for QDeadlineTimer unit test
Apparently, the CI can run something over 1000x slower than on my
machine. We're getting over 100 ms delays in operations that shouldn't
have taken more than half a millisecond. The last report was of 136%
over budget, so I multiplied the resolution by 4.

12eacc3bab Long live QDeadlineTimer
It's like QElapsedTimer, but marks a time in the future instead.

[ChangeLog][QtCore] Added QDeadlineTimer, a counterpart to
QElapsedTimer, used to mark a time point in the future (a deadline) and
determine whether such a deadline has passed.
