There's doesn't seem to be much use in independently distributing these
subdirectories, so allowing them to be independently configured seems
pointless and overcomplicated.
The order in which the subdirectories are built is still a little odd,
as cygwin is linked with libcygserver, and cygserver is then linked with
cygwin. So, we build the cygwin directory first, which invokes a build
of libcygserver in the cygserver directory, and then build in the
cygserver directory to build the cygserver executable.
Drop AC_CONFIGURE_ARGS, since we don't need to recursively call
configure with the same arguments anymore.
Slightly refine when we build utils: Previously we didn't build any
utils if MinGW compiler use was avoided, now we just avoid building
those utils which require that compiler.
Greatly simplify how winsup_srcdir and target_builddir are set, since
we're only configuring from one directory. (These are still kept
absolute, since we don't adjust them where used for being used in a
subdirectory).
Remove configure.cygwin and put it's (greatly reduced) contents inline
in the one place it's used now.
Remove generated configure and aclocal.m4 in subdirectories.

Use the (undocumented) MEMORY_WORKING_SET_EX_INFORMATION in dumper to
determine if a MEM_IMAGE region is unsharable, and hence has been
modified.
After this, we will end up dumping memory regions where:
- state is MEM_COMMIT (i.e. is not MEM_RESERVE or MEM_FREE), and
-- type is MEM_PRIVATE and protection allows reads (i.e. not a guardpage), or
-- type is MEM_IMAGE and attribute is non-sharable (i.e. it was WC, got
written to, and is now a RW copy)
Windows Explorer shows a warning with Cygwin-created DACLs, but putting
the text of the warning into Google doesn't lead to the relevant Cygwin
docs. Let's copy the warning text into the docs in the hopes of helping
confused users. Most of the credit for the wording belongs to Yaakov
Selkowitz.

The implicit assumption seemed to be that any subsequent occurence of
the same setting in nsswitch.conf is supposed to rewrite the previous
ones completely. This was not the case if the third or any further
schema was previously defined and the last line defined less than that
(but at least 2), for example:
```
db_home: windows cygwin /myhome/%U
db_home: cygwin desc
```
Let's document this behavior as well.

The descriptions of symlink handling are a bit dated, so
revamp them and add the new WSL symlink type.
Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
WSL symlinks are reparse points containing a POSIX path in UTF-8.
On filesystems supporting reparse points, use this symlink type.
On other filesystems, or in case of error, fall back to the good
old plain SYSTEM file.

Treat WSL symlinks just like other symlinks. Convert
absolute paths pointing to Windows drives via
/mnt/<driveletter> to Windows-style paths <driveletter>:

- For programs which does not work properly with pseudo console,
disable_pcon in environment CYGWIN is introduced. If disable_pcon
is set, pseudo console support is disabled.
This patch supplies an implementation of the CPU_SET(3) processor
affinity macros as documented on the relevant Linux man page.
There is a mostly superset implementation of cpusets under newlib's
libc/sys/RTEMS/include/sys that has Linux and FreeBSD compatibility
and is built on top of FreeBSD bitsets. This Cygwin implementation
and the RTEMS one could be combined if desired at some future point.
This patch set implements the Linux syscalls sched_getaffinity,
sched_setaffinity, pthread_getaffinity_np, and pthread_setaffinity_np.
Linux has a straightforward view of the cpu sets used in affinity masks.
They are simply long (1024-bit) bit masks. This code emulates that view
while internally dealing with Windows' distribution of available CPUs among
processor groups.
libX11 provides <X11/Xlocale.h>. The build of libX11 itself adds
include/X11 to the compiler's include path. This results in a name
collision with /usr/include/xlocale.h on case-insensitive filesystems.
Commit 90e35b1eb3df renamed sys/_locale.h to xlocale.h in March 2017 under
the assumption that we should provide the locale_t type in the same file
as on Linux, FreeBSD, and Darwin.
A few weeks later (June 2017), glibc removed the xlocale.h file in favor
of bits/types/locale_t.h, which shouldn't be included directly anyway.
For reference and the reasoning, see
https://sourceware.org/git/?p=glibc.git;a=commit;h=f0be25b6336d
Given the above, revert 90e35b1eb3df4070e68afc5e7060665214d586be and
fix additional usage of xlocale.h.
