Corinna Vinschen e18f7f99cc Cygwin: memory: declare extended memory API
Windows 10 1803 introduced an extended memory API allowing
to specify memory regions allocations are to be taken off.

In preparation of using this API, define the struct
MEM_EXTENDED_PARAMETER and friends.  Declare and allow to
autoload the functions VirtualAlloc2 and NtMapViewOfSectionEx.

Introduce a wincap flag has_extended_mem_api.

Takashi Yano bb30582a99 Cygwin: pty: Add missing CloseHandle() calls.
- PTY code which support pseudo console has a problem that causes
  handle leaks. Four of these are bug in pty code, and the other
  one seems to be a bug of Windows10. ClosePseudoConsole() fails
  to close one internal handle. This patch fixes the issue.

Ken Brown 3bc79b275e Cygwin: FIFO: use FILE_PIPE_REJECT_REMOTE_CLIENTS flag
Add that flag to the pipe type argument when creating the Windows
named pipe.  And add a definition of that flag to ntdll.h (copied from
/usr/include/w32api/ddk/ntifs.h).

Ken Brown bb46627871 Cygwin: FIFO: improve raw_write
Don't set the write end of the pipe to non-blocking mode if the FIFO
is opened in blocking mode.

In fhandler_fifo::raw_write in blocking mode, wait for the write to
complete rather than returning -1 with EAGAIN.

If the amount to write is large, write in smaller chunks (of size
determined by a new data member max_atomic_write), as in
fhandler_base_overlapped.

For convenience, add two new NTSTATUS codes, STATUS_THREAD_SIGNALED
and STATUS_THREAD_CANCELED, to ntdll.h.

Corinna Vinschen c05df02725 Cygwin: implement extensible clock interface
- Drop hires_[nm]s clocks, rename hires.h to clock.h.

- Implement clk_t class as an extensible clock class in new file clock.cc.

- Introduce get_clock(clock_id) returning a pointer to the clk_t instance
  for clock_id.  Provide the following methods along the lines of the former
  hires classes:

	void		clk_t::nsecs (struct timespec *);
	ULONGLONG	clk_t::nsecs ();
	LONGLONG	clk_t::usecs ();
	LONGLONG	clk_t::msecs ();
	void 		clk_t::resolution (struct timespec *);

- Add CLOCK_REALTIME_COARSE, CLOCK_MONOTONIC_RAW, CLOCK_MONOTONIC_COARSE
  and CLOCK_BOOTTIME clocks.

- Allow clock_nanosleep, pthread_condattr_setclock and timer_create to use
  all new clocks (both clocks should be usable with a small tweak, though).

- Bump DLL major version to 2.12.

Corinna Vinschen 48511f3d38 Overwite potentially faked kernel version with correct values
* ntdll.h (RtlGetNtVersionNumbers): Declare.
	* wincap.cc (wincapc::init): Overwrite kernel version info
	returned by RtlGetVersion with correct info returnd by
	RtlGetNtVersionNumbers.  Add comment.

Originally, using RtlGetVersion instead of GetVersionEx was supposed to
fix the fact that GetVersionInfo returns the wrong kernel version if the
executable has been built with an old manifest (or none at all), starting
with Windows 8.1.  Either this never really worked as desired and our
testing was flawed, or this has been changed again with Windows 10, so
that RtlGetVersion does the kernel faking twist as well.  Since we're
only reading the value in the first process in a process tree. the entire
process tree is running with a wrong OS version information in that case.

Fortunately, the (undocumented) RtlGetNtVersionNumbers function is not
affected by this nonsense, so we simply override the OS version info
fields with the correct values now.

	for event object handle count to become <= 1 in F_LOCK case.
	Simplify WFMO return value handling.  Don't handle signal and cancel
	events here; just return with appropriate error code instead.
	(lf_getblock): Ignore locks for which the handle can't be opened.
