Always use the __-decorated form of an attribute name in public
headers, as the bareword form is in the user's namespace, and we
don't want compilation to break just because the user defines the
bareword to mean something else.

- pthread_mutex::lock now takes a PLARGE_INTEGER timeout pointer
and uses that in the call to cygwait.

- Introduce inline helper pthread_convert_abstime. It converts
an absolute timespec to a Windows LARGE_INTEGER timestamp,
depending on the used clock.
- Use this function from pthread_cond_timedwait and semaphore::timedwait
- Merge semaphore::_wait and semaphore::_timedwait into single _wait
method, taking a LARGER_INTEGER timestamp.

This is copied from musl (MIT license). This is newer and more thorough
than that of FreeBSD currently shipped only on Cygwin.

For historical reasons peek_console was calling the functions
PeekConsoleInputA and ReadConsoleInputA. However, these functions are
not working correctly under at least codepage 65001 (UTF-8) on systems
prior to Windows 10.
Use PeekConsoleInputW and ReadConsoleInputW instead, which work
correctly under all systems and all codepages.

FillConsoleOutputCharacterA doesn't work correctly in codepage 65001
(UTF-8). Looks like the character conversion function from ascii char
to unicode char works incorrectly then. Use FillConsoleOutputCharacterW
instead.

So far we had two functions checking the content of a reparse point,
readdir_check_reparse_point in fhandler_disk_file.cc for the sake of
readdir, and symlink_info::check_reparse_point for the sake of
generic path checking.
* Rename check_reparse_point_target helper to check_reparse_point_string
and convert to static function.
* Create new check_reparse_point_target helper containing the core
reparse point checking code
* Just call check_reparse_point_target from readdir_check_reparse_point
and symlink_info::check_reparse_point and only perform the unique
task in those functions.

struct sigaction is POSIX.1-1990 but siginfo_t, which is used by its
sa_sigaction member, is POSIX.1b-1993. Therefore it needs to be guarded
as well, and as part of a union, the struct size is protected.

When SA_RESTART is not set on a socket, a blocking send() that is
interrupted mid-transition by a signal should return success (and
report just how many bytes were actually transmitted).
The err variable used here was not always guaranteed to be set
correctly in the loop, so better to just remove it and call
WSAGetLastError() explicitly.
There are two common sigpause variants, both of which take an int argument.
If you request _XOPEN_SOURCE or _GNU_SOURCE, you get the System V version,
which removes the given signal from the process's signal mask; otherwise
you get the BSD version, which sets the process's signal mask to the given
value.

So far Cygwin's readdir returned the inode number of a mount target
in d_ino, rather than the actual inode number of the mount point in
the underlying filesystem. This not only results in a performance
hit if the mount target is a remote FS, it is also not done on other
POSIX systems.
Remove the code evaluating the mount target inode number.

This patch fixes a minor compatibility issue w/ cygwin mount point handling in
readdir(), compared to equivalent behavior of Linux and MacOS. dentry.d_ino
should indicate the INO of the mount point itself, not the target volume root
folder.
Changed return type from readdir_check_reparse_point to uint8_t, to avoid
unnecessarily being implicitly cast to and from a signed int.
Renamed a related local variable "attr" to "oattr" that was eclipsing a member
variable with the same name.

Mingw-w64 (where the code has been taken from) has 4 byte longs
independently of the architecture but x86_64 Cygwin has 64 bit longs.
So use fistpll instead of fistpl on x86_64 Cygwin.
