These tests async thread cancellation of a thread that doesn't have any
cancellation points.
Unfortunately, since 2b165a45 the async cancellation silently fails when
the thread is inside the kernel function Sleep(), so it just exits
normally after 10 seconds. (See the commentary in pthread::cancel() in
thread.cc, where it checks if the target thread is inside the kernel,
and silently converts the cancellation into a deferred one)
Work around this by busy-waiting rather than Sleep()ing for 10 seconds.
This is still somewhat fragile: the async cancel could still fail, if it
happens to occur while we're inside the kernel function that time()
calls.

Since commit 4b51e4c1, we return the actual thread priority, not what we
originally stored in the thread attributes.
Windows only supports 7 thread priority levels, which we map onto the 32
required by POSIX. So, only a subset of values will be returned exactly
by by pthread_getschedparam() after pthread_setschedparam().
Adjust tests priority1, priority2 and inherit1 so they only check for
round-tripping priority values which can be exactly represented.
For CI, this needs to handle process priority class "below normal
priority" as well.
Also check that the range of priority values is at least 32, as required
by POSIX.

The current version of <sys/cpuset.h> cannot be compiled by Clang due to
the use of builtin versions of malloc, free, and memset. Their presence
here was a dubious optimization anyway, so their usage has been
converted to standard library functions.
The use of __builtin_popcountl remains because Clang implements it just
like gcc does. If/when some other compiler (Rust? Go?) runs into this
issue we can deal with specialized handling then.
The "#include <sys/cdefs>" here to define __inline can be removed since
both of the new includes sub-include it.

While st_rdev returned by fstat() for /dev/tty should be FH_TTY,
the current cygwin1.dll returns FH_PTYS+minor or FH_CONS+minor.
Similarly, fstat() does not return correct value for /dev/console,
/dev/conout, /dev/conin or /dev/ptmx.
This patch fixes the issue by:
1) Introduce dev_referred_via in fhandler_termios.
2) Add new argument, which has dev_t value referred by open(),
for constructors of fhandler_pty_slave and fhandler_pty_master to
set the value of dev_referred_via.
3) Set st_rdev using dev_referred_via in fhandler_termios::fstat()
if it is available.

As reported in
https://cygwin.com/pipermail/cygwin/2023-June/253888.html,
"Bad address" error occurs when stat() is called after the commit
3721a756b0 ("Cygwin: console: Make the console accessible from
other terminals.").
There are two problems in the current code. One is fhandler_console::
fstat() calls get_ttyp()->getsid(). However, fh_alloc() in dtable.cc
omits to initialize the fhandler_console instance when stat() is
called. Due to this, get_ttyp() returns NULL and access violation
occurs. The other problem is fh_alloc() assigns fhandler_console
even if the CTTY is not a console. So the first problem above occurs
even if the CTTY is a pty.
This patch fixes the issue by:
1) Call set_unit() to initialize _tc if the get_ttyp() returns NULL.
2) Assign fhandler_pty_slave for /dev/tty if CTTY is a pty in fh_alloc().

For example, for GCC/GCN target (AMD GPUs), target libraries are built
individually per supported hardware ISA ('-march=[...]'). Testing such a
toolchain via, for example:
$ make RUNTESTFLAGS='--target_board=[...]/-march=gfx90a' check[...]
... does work fine for all 'check-gcc-[...]' as well as GCC-provided target
libraries, 'check-target-[...]'. Just for 'check-target-newlib', for the
example above, not the '-march=gfx90a' newlib libraries are linked in, but
instead always the default ones, which results in link FAILure. This is cured
simply by skipping use of 'newlib/testsuite/lib/flags.exp', so that the
standard search paths as determined by GCC, DejaGnu are used for newlib, too.

In the very early code path where `dll_crt0_1 ()` calls
`user_shared->initialize ()`, the Cygwin runtime calls `internal_pwsid ()`
to initialize the user name in preparation for reading the `fstab` file.
In case `db_home: env` is defined in `/etc/nsswitch.conf`, we need to
look at the environment variable `HOME` and use it, if set.
When all of this happens, though, the `pinfo_init ()` function has had no
chance to run yet (and therefore, `environ_init ()`). At this stage,
therefore, `getenv ()`'s `findenv_func ()` call still finds `getearly ()`
and we get the _verbatim_ value of `HOME`. That is, the Windows form.
But we need the "POSIX" form.
To add insult to injury, later calls to `getpwuid (getuid ())` will
receive a cached version of the home directory via
`cygheap->pg.pwd_cache.win.find_user ()` thanks to the first
`internal_pwsid ()` call caching the result via
`add_user_from_cygserver ()`, read: we will never receive the converted
`HOME` but always the Windows variant.
So, contrary to the assumptions made in 27376c60a9 (Allow deriving the
current user's home directory via the HOME variable, 2023-03-28), we
cannot assume that `getenv ("HOME")` returned a "POSIX" path.
This is a real problem. Even setting aside that common callers of
`getpwuid ()` (such as OpenSSH) are unable to handle Windows paths in the
`pw_dir` attribute, the Windows path never makes it back to the caller
unscathed. The value returned from `fetch_home_env ()` is not actually
used as-is. Instead, the `fetch_account_from_windows ()` method uses it
to write a pseudo `/etc/passwd`-formatted line that is _then_ parsed via
the `pwdgrp::parse_passwd ()` method which sees no problem with
misinterpreting the colon after the drive letter as a field separator of
that `/etc/passwd`-formatted line, and instead of a Windows path, we now
have a mere drive letter.
Let's detect when the `HOME` value is still in Windows format in
`fetch_home_env ()`, and convert it in that case.
For good measure, interpret this "Windows format" not only to include
absolute paths with drive prefixes, but also UNC paths.

The account under which Azure Web Apps run is an IIS APPOOL account that
is generated on the fly.
These are special because the virtual machines on which thes Apps run
are not domain-joined, yet the accounts are domain accounts.
To support the use case where such a Web App needs to call `ssh` (e.g.
to deploy from a Git repository that is accessible only via SSH), we do
need OpenSSH's `getpwuid (getuid ())` invocation to work.
But currently it does not. Concretely, `getuid ()` returns -1 for these
accounts, and OpenSSH fails to find the correct home directory
(_especially_ when that home directory was overridden via a `db_home:
env` line in `/etc/nsswitch.conf`).
This can be verified e.g. in a Kudu console (for details about Kudu
consoles, see https://github.com/projectkudu/kudu/wiki/Kudu-console):
the domain is `IIS APPPOOL`, the account name is the name of the Azure
Web App, the SID starts with 'S-1-5-82-`, and
`pwdgrp::fetch_account_from_windows()` runs into the code path where
"[...] the domain returned by LookupAccountSid is not our machine name,
and if our machine is no domain member, we lose. We have nobody to ask
for the POSIX offset."
Since these IIS APPPOOL accounts are relatively similar to AzureAD
accounts in this scenario, let's imitate the latter to support also the
former.
