mingw: make isatty() recognize MSYS2's pseudo terminals (/dev/pty*)kb/msys2-tty
MSYS2 emulates pseudo terminals via named pipes, and isatty() returns 0 for such file descriptors. Therefore, some interactive functionality (such as launching a pager, asking if a failed unlink should be repeated etc.) doesn't work when run in a terminal emulator that uses MSYS2's ptys (such as mintty). However, MSYS2 uses special names for its pty pipes ('msys-*-pty*'), which allows us to distinguish them from normal piped input / output. On startup, check if stdin / stdout / stderr are connected to such pipes using the NtQueryObject API from NTDll.dll. If the names match, adjust the flags in MSVCRT's ioinfo structure accordingly.
