Takashi Yano bd627864ab Cygwin: console: support 24 bit color
- Add 24 bit color support using xterm compatibility mode in
  Windows 10 1703 or later.
- Add fake 24 bit color support for legacy console, which uses
  the nearest color from 16 system colors.

Corinna Vinschen 649911fb40 Cygwin: get_user_groups: fetch a user's group list from identification token
NetUserGetGroups and NetUserGetLocalGroups sometimes take a lot of time
(up to more than 2 mins) for no apparent reason.

Call s4uauth to generate an identification token for the user and fetch
the group list from there.  This is *much* faster.

Keep the old code only for the sake of WOW64 on Vista and Windows 7,
which don't implement MsV1_0S4ULogon.

Corinna Vinschen 5a0f2c00aa Cygwin: fork/exec: fix child process permissions
- Exec'ed/spawned processes don't need PROCESS_DUP_HANDLE.  Remove that
  permission from the parent handle.

- PROCESS_QUERY_LIMITED_INFORMATION doesn't work for Windows 7 if the
  process is started as a service.  Add PROCESS_QUERY_INFORMATION for
  pre-Windows 8 in that case.

Corinna Vinschen 5275b3e3f2 Cygwin: wincap: split has_posix_file_info
While FileRenameInformationEx is defined starting with Windows
10 1709 per MSDN, it only starts working in W10 1809, apparently.
Users of 1803 report "Function not implemented".

Introduce wincap_10_1809 and change the version check in
wincapc::init accordingly.  Split has_posix_file_info into
has_posix_unlink_semantics and has_posix_rename_semantics.
Enable the latter only starting with W10 1809.

Corinna Vinschen 092a768885 Cygwin: wincap: add wincap_10_1709, add has_posix_file_info item
Various new file info class members adding important POSIX semantics
have been added with W10 1709.  We may want to utilize them, so add
a matching wincaps.

Rearrange checking the W10 build number to prefer the latest builds
over the older builds.  Rename wincap_10 to wincap_10_1507 for
enhanced clarity.

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 67fd2101ab Drop max_sys_priv wincap
Convert sys_privs to const struct with TOKEN_PRIVILEGES layout.
Drop function get_system_priv_list.  Just use pointer to sys_privs.

Dropping max_sys_priv from wincaps requires to make sure that the
bitfield is 8 byte aligned on x86_64, otherwise gcc (5.3 only?)
apparently breaks access to the bitfield (off by 4 bytes).
