- In Win10 upto 1809, xterm compatible mode does not have REP
escape sequence which terminfo declares. This patch adds support
for "CSI Ps b" (REP). With this patch, bvi (binary editor) works
normally in Win10 1809. Also, xterm compatible mode does not have
"CSI Pm `" (HPA), "CSI Pm a" (HPR) and "CSI Ps e" (VPR). However,
they do not appear to be declared by terminfo. Therefore, these
have been pending.

- Cygwin console with xterm compatible mode causes problem reported
in https://www.cygwin.com/ml/cygwin-patches/2020-q1/msg00212.html
if background/foreground colors are set to gray/black respectively
in Win10 1903/1909. This is caused by "CSI Ps L" (IL), "CSI Ps M"
(DL) and "ESC M" (RI) control sequences which are broken. This
patch adds a workaround for the issue.

- In Win10 1809, the cursor position sometimes goes out of screen
by clear command in console. This seems to be caused by escape
sequence CSI3J (ESC[3J). This happens only for 1809. This patch
is a workaround for the issue.

64 bit Windows started out with a 44 bit address space due to a
restriction of the AMD64 CPUs at the time. Starting with Windows
8.1, these CPUs are not supported anymore and Windows switched to
the full 48 bit address space supported by AMD64.
Cygwin didn't follow suit yet so mmaps are still restricted to
the lower 44 bit address space. Fix that by using a system-specific
upper address for mmap allocations, 44 bit up to Windows 8, 48 bit
starting with Windows 8.1.
While at it, move the heap by another 8 Gigs to leave some space
for a potential extension of DLL address space, and restrict the
mmap lower address so the heap can grow to 32 Gigs before colliding
with mmaps.

* Pre-release version still reporting kernel version 6.4.
* Windows 10 1511 is out of support since 2017-10-10.

- 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.

Per MSDN VirtualQueryEx requires PROCESS_QUERY_INFORMATION.
Testing showed that PROCESS_QUERY_LIMITED_INFORMATION is sufficient
since Windows 8.1. The assumption that Windows 8 is the same as
Windows 8 was not correct, it requires PROCESS_QUERY_INFORMATION
as well.
Fix that by splitting the Windows 8 wincaps into one for Windows 8
and one for Windows 8.1. Set needs_query_information for Windows 8.

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.

- 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.

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.

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.

- 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.

RtlGetNtVersionNumbers returns the build number with some upper bits
set for no apparent reason. The fact that RtlGetNtVersionNumbers is
undocumented doesn't exactly help.
Just filter out the upper WORD for now. If build numbers are in
danger to become 6 digit numbers, re-evaluate.

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).

* 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.

Observed running hexchat under X. For some reason the call to
LoadLibraryEx(..., LOAD_LIBRARY_SEARCH_SYSTEM32) in dll_load
hangs when trying to autoload MsgWaitForMultipleObjectsEx in
select.cc after hexchat forks to run DNS calls. Dropping the
call and just using full paths as in 2.3.1 fixes the issue.

LOAD_LIBRARY_SEARCH_SYSTEM32 flag.
