Prior to 1.19, libuv does not use SA_RESTART in its signal handler.
Add a helper to cause libuv to install its handler and then revise
the handler's flags to add SA_RESTART.
If `StartTestProcess` does not start a test, propagate this information
back up to the `StartNextTests` loop so that it can move on to another
candidate without allocating processors to a test that didn't run.
Otherwise we have to wait for the next time `RunTests` loops around and
calls `StartNextTests` again.
Avoid creating a cmCTestRunTest instance if the stop time has been
reached. If the stop time occurs in the small time between creating an
instance and computing the child process timeout, we will simply compute
a zero timeout. This is already done for the case that we StartAgain
after the stop time.
This member was added by commit v2.8.2~285 (Better detection of
stop_time being passed, 2010-03-19), but its logic has no effect.
The member is only used for comparison against a value to which
it was just assigned.
BSD `signal(2)` semantics make some system calls (e.g. for `write`)
restartable when interrupted by a signal handler. Use `SA_RESTART` to
enable these semantics everywhere that supports them.
This is required by C++ stream libraries that interpret `EINTR` as any
other error, set `badbit`, and stop writing. I've observed this with
`libstdc++` during a `std::cout.flush()` call interrupted by `SIGCHLD`.

UTF-8 is the proper naming according to the UTF-8 RFC and is also the
name used for a similar keyword in the file() command. This commit
brings (backward compatible) consistency to the keyword names and allows
the standard UTF-8 name to be used with execute_process(). The old UTF8
keyword is still supported.

Add a check that a simple source file can compile as C++17 that uses
some of the features we need. Do this only when hosted by CMake 3.8
or above because those versions are aware of C++17.
Check for unordered_map as we do in bootstrap since commit 375eca7881
(bootstrap: Check support for unordered_map from compiler mode,
2017-11-30). Also maintain the existing C++14 cstdio check.
The check for C++14 and cstdio is a special case of the more general
problem of checking that the compiler's C++14 mode supports everything
we need. Rename the checks accordingly.
