2902b3a09e Cygwin: drop requirement to build newlib's stdio64
Given that 64 bit Cygwin defines all file access types (off_t,
fpos_t, and derived types) as 64 bit anyway, there's no reason
left to rely on the stdio64 part of newlib.  Use base functions
and base types.

5d4f405d3b Cygwin: redefine some macros for Linux compatibility
Define FD_SETSIZE (<sys/select.h>) to be 1024 by default, and define
NOFILE (<sys/param.h>) to be OPEN_MAX (== 3200) by default.

Remove the comment in <sys/select.h> that FD_SETSIZE should be >=
NOFILE.

Bump API minor.

bbfe79fb72 Cygwin: restore '#ifdef __x86_64__' for CPU-specific code
Commit e1ce752a1d, "Cygwin: remove miscellaneous 32-bit code", removed
most occurrences of '#ifdef __x86_64__'.  Restore those occurrences
that guarded code specific to the AMD64 processor, and #error out if
the processor is different.  This will make it easier to find
AMD64-specific code if we ever want to add support for a different
64-bit processor (e.g., ARM64).

b0cb9f85ca Use global stdio streams for all configurations
The _REENT_GLOBAL_STDIO_STREAMS was introduced by commit
668a4c8722090fffd10869dbb15b879651c1370d in 2017.  Since then it was enabled by
default for RTEMS.  Recently, the option was enabled for Cygwin which
previously used an alternative implementation to use global stdio streams.

In Newlib, the stdio streams are defined to thread-specific pointers
_reent::_stdin, _reent::_stdout and _reent::_stderr.  If the option is disabled
(the default for most systems), then these pointers are initialized to
thread-specific FILE objects which use file descriptors 0, 1, and 2,
respectively.  There are at least three problems with this:

(1) The thread-specific FILE objects are closed by _reclaim_reent().  This
    leads to problems with language run-time libraries that provide wrappers to
    the C/POSIX stdio streams (for example C++ and Ada), since they use the
    thread-specific FILE objects of the initialization thread.  In case the
    initialization thread is deleted, then they use freed memory.

(2) Since thread-specific FILE objects are used with a common output device via
    file descriptors 0, 1 and 2, the locking at FILE object level cannot ensure
    atomicity of the output, e.g. a call to printf().

(3) There are resource managment issues, see:

    https://sourceware.org/pipermail/newlib/2022/019558.html

    https://bugs.linaro.org/show_bug.cgi?id=5841

This patch enables the _REENT_GLOBAL_STDIO_STREAMS behaviour for all Newlib
configurations and removes the option.  This removes a couple of #ifdef blocks.

30c5411d07 Cygwin: remove most occurrences of __stdcall and __cdecl
These have no effect on x86_64.  Retain a few occurrences of __cdecl
in files imported from other sources.

Also retain all occurrences of WINAPI, even though the latter is
simply a macro that expands to __stdcall.  Most of these occurrences
are associated with Windows API functions, and removing them might
make the code confusing instead of simpler.

acltomode32, acltopbits32, acltotext32, facl32, fchown32, fcntl64,

7c0de0af97 Cygwin: remove some 32-bit-only function definitions
Remove the definitions of the following: acl, aclcheck, aclfrommode,
aclfrompbits, aclfromtext, aclsort, acltomode, acltopbits, acltotext,
chown, fchown, _fcntl, fstat, _fstat_r, ftruncate, getegid, geteuid, getgid,
getgrent, getgrgid, getgrnam, getgroups, getpwduid, getpwuid,
getpwuid_r, getuid, initgroups, lacl, lacl32, lchown, lseek, lstat,
mknod, mmap, setegid, seteuid, setgid, setgroups, setregid, setreuid,
setuid, stat, _stat_r, truncate.

[For most of these, the corresponding 64-bit entry points are obtained
by exporting aliases.  For example, acl is an alias for acl32, and
truncate is an alias for truncate64.]

Remove the following structs and all code using them (which is 32-bit
only): __stat32, __group16, __flock32, __aclent16_t.

Remove the typedefs of __blkcnt32_t __dev16_t, __ino32_t, which are
used only in code that has been removed.

Put the typedefs of __uid16_t and __gid16_t in one header, instead of
one header if __INSIDE_CYGWIN__ is defined and a different header
otherwise.

d4fa3b4abb Cygwin: config.h: stop including auto-generated tlsoffsets.h file
This was a hack to begin with.  Clean this mess up:

- Move definition of CYGTLS_PADSIZE to cygwin/config.h and drop
  local cygtls_padsize.h
- Rename CYGTLS_PADSIZE to __CYGTLS_PADSIZE__ to keep namespace
  clean.  Redefine as macro, rather than as const.
- Move struct _reent first in struct _cygtls to allow using
  __CYGTLS_PADSIZE__ as offset in __getreent().

23b1400f83 Cygwin: Make native clipboard layout same for 32- and 64-bit
This patch unifies the layout of the clipboard descriptor cygcb_t for
32- and 64-bit Cygwin.  It allows correct copy/paste between the two
environments without corruption of user's copied data and without access
violations due to interpreting that data as a size field.

The definitions of CYGWIN_NATIVE and cygcb_t are moved to a new include
file, sys/clipboard.h.  The include file is used by fhandler_clipboard.cc
as well as getclip.c and putclip.c in the Cygwin cygutils package.

When copy/pasting between 32- and 64-bit Cygwin environments, both must
be running version 3.3.0 or later for successful operation.

582628d551 Revert "Cygwin: Make sure newer apps get uname_x even when loading uname dynamically"
This reverts commit 532b91d24e9496c7988b2b1dda7fc0e8b161f782.

It turned out that this patch has undesired side effects.  To wit, if a
newer, post-uname_x executable was linked against or loading an older,
pre-uname_x DLL, and this DLL called uname.  This call would jump into
the old uname with the old struct utsname as parameter, but given the
newer executable it would get redirected to uname_x.  uname_x in turn
would overwrite stack memory it should leave well alone, given it
expects the newer, larger struct utsname.

For the entire discussion see the thread starting at
https://cygwin.com/pipermail/cygwin/2021-February/247870.html
and continuing in March at
https://cygwin.com/pipermail/cygwin/2021-March/247930.html
For a description where we're coming from, see
https://cygwin.com/pipermail/cygwin/2021-March/247959.html

While we *could* make the scenario in question work by patching dlsym,
the problem would actually be the same, just for dynamic loading.  In
the end, we're missing the information, which Cygwin version has been
used when building DLLs.
