msvcrt: Fix EOF behavior on read from pipe or console.
...
The canonical way to detect EOF on read is when you request more than
zero bytes, but zero bytes come back. Switching to this method seems
to handle a few problem cases better. Also handle ERROR_BROKEN_PIPE
properly just in case.

msvcrt: Fix fstat's handling of pipes and char devices.

is always 1, and st_mode is S_IFIFO and S_IFCHR respectively.
Added tests to prove the new behaviour right.
