- Use the helper for gdbm & dlerror messages

* Correct pthread_sigmask in resource_tracker to restore old signals
Using SIG_UNBLOCK to remove blocked "ignored signals" may accidentally
cause side effects if the calling parent already had said signals
blocked to begin with and did not intend to unblock them when
creating a pool. Use SIG_SETMASK instead with the previous mask of
blocked signals to restore the original blocked set.
* Adding resource_tracker blocked signals test

The strace_helper code has a _make_error function to simplify making
StraceResult objects in error cases. That takes a details parameter
which is either a caught OSError or `bytes`. If it's bytes, _make_error
would implicitly coerce that to a str inside of a f-string, resulting in
a BytesWarning.
It's useful to see if it's an OSError or bytes when debugging, resolve
by changing to format with repr().
This is an error message on an internal helper.
A non-zero exit code occurs if the strace binary isn't found, and no
events will be parsed in that case (there is no output). Handle that
case by checking exit code before checking for events.
Still asserting around events rather than returning false, so that
hopefully if there's some change to `strace` that breaks the parsing,
will see that as a test failure rather than silently loosing strace
tests because they are auto-disabled.
We use the same approach that was used for specialization of LOAD_GLOBAL in free-threaded builds:
_CHECK_ATTR_MODULE is renamed to _CHECK_ATTR_MODULE_PUSH_KEYS; it pushes the keys object for the following _LOAD_ATTR_MODULE_FROM_KEYS (nee _LOAD_ATTR_MODULE). This arrangement avoids having to recheck the keys version.
_LOAD_ATTR_MODULE is renamed to _LOAD_ATTR_MODULE_FROM_KEYS; it loads the value from the keys object pushed by the preceding _CHECK_ATTR_MODULE_PUSH_KEYS at the cached index.
This method helped us customise the `UnsupportedOperation` message
depending on the type. But we're aiming to make `PathBase` a proper ABC
soon, so `NotImplementedError` is the right exception to raise there.
Remove the following methods from `pathlib._abc.PathBase`:
- `expanduser()`
- `hardlink_to()`
- `touch()`
- `chmod()`
- `lchmod()`
- `owner()`
- `group()`
- `from_uri()`
- `as_uri()`
These operations aren't regularly supported in virtual filesystems, so they
don't win a place in the `PathBase` interface. (Some of them probably don't
deserve a place in `Path` :P.) They're quasi-abstract (except `lchmod()`),
and they're not called by other `PathBase` methods.
The function `operator.methodcaller` was not thread-safe since the additional
of the vectorcall method in gh-89013. In the free threading build the issue
is easy to trigger, for the normal build harder.
This makes the `methodcaller` safe by:
* Replacing the lazy initialization with initialization in the constructor.
* Using a stack allocated space for the vectorcall arguments and falling back
to `tp_call` for calls with more than 8 arguments.
Remove `PathBase.samefile()`, which is fairly specific to the local FS, and
relies on `stat()`, which we're aiming to remove from `PathBase`.
Also remove `PathBase.is_mount()`, `is_junction()`, `is_block_device()`,
`is_char_device()`, `is_fifo()` and `is_socket()`. These rely on POSIX
file type numbers that we're aiming to remove from the `PathBase` API.

Change the default value of `PurePathBase.parser` from `ParserBase()` to
`posixpath`. As a result, user subclasses of `PurePathBase` and `PathBase`
use POSIX path syntax by default, which is very often desirable.
Move `pathlib._abc.ParserBase` to `pathlib._types.Parser`, and convert it
to a runtime-checkable protocol.
