- GHA/macos: set timeout for test runs.
Double the value for autotools to fit torture tests.
- GHA/cygwin: reduce test run timeout for autotools.
- GHA/cygwin: enable building tests with cmake.
- GHA/windows: enable building tests with MSYS cmake.
- GHA/windows: enable building tests with MSVC UWP.
- appveyor: enable building tests with VS2008 x86 and VS2010 x64.
- tests: add workaround compiler warnings when building with VS2010:
```

With this, tests are built in all GHA cygwin/windows jobs.
Timeouts avoid long runs with runaway issues, example:
