py3: remove retry on EINTR errno
Since the implementation of PEP 475 (Python 3.5), Python retries system calls
failing with EINTR. Therefore we don’t need the logic that retries it in Python
code.

tests: assume that `raw` attribute is present on original socket file object
It seems like the original socket file object is always an io.BufferedIO
instance. If not, the code will fail and we should try harder to get the socket
object (e.g. if the original socket file object is unbuffered, we can get the
`_sock` attribute directly from it).

zeroconf: constant-fold a `pycompat.ispy3`
I’ve checked that both bytes and str gets passed as the `name` parameter, so
the rest of the condition is still required. Because there aren’t really any

thirdparty: remove Python 2-specific selectors2 copy
The selectors module was added in Python 3.4. Because we require Python 3.6, it
will always be available. Therefore the selectors2 module is not imported.
I’ve verified that the selectors2-specific workaround in commandserver.py is not
necessary with the selectors module from the standard library. It returns an
empty list if timeout was exceeded.
The pytype directive was needed to silence the following error:
File "/tmp/mercurial-ci/mercurial/worker.py", line 299, in _posixworker: No attribute 'close' on int [attribute-error]
In Union[_typeshed.HasFileno, int]

chg: replace mercurial.util.recvfds() by simpler pure Python implementation
On Python 3, we have socket.socket.recvmsg(). This makes it possible to receive
FDs in pure Python code. The new code behaves like the previous
implementations, except that it’s more strict about the format of the ancillary
data. This works because we know in which format the FDs are passed.
Because the code is (and always has been) specific to chg (payload is 1 byte,
number of passed FDs is limited) and we now have only one implementation and
the code is very short, I decided to stop exposing a function in
mercurial.util.
Note on terminology: The SCM_RIGHTS mechanism is used to share open file
descriptions to another process over a socket. The sending side passes an array
of file descriptors and the receiving side receives an array of file
descriptors. The file descriptors are different in general on both sides but
refer to the same open file descriptions. The two terms are often conflated,
even in the official documentation. That’s why I used “FD” above, which could
mean both “file descriptor” and “file description”.

parsers: drop one extra argument to PyErr_Format
GCC gave the following warning during `make local`:
mercurial/cext/parsers.c: In function 'dirstate_item_from_v1_data':
mercurial/cext/parsers.c:413:30: warning: too many arguments for format [-Wformat-extra-args]
413 | "unknown state: `%c` (%d, %d, %d)", state, mode,
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
To reproduce, you might need to add the -Wformat-extra-args flag, because it
isn't present for me when building for the default python3. But I can see this
warning while simply building 6.1 with `make PYTHON=python2 clean local`.
I don't think this NULL was useful, because other instances of PyErr_Format()
don't have any NULLs as the final argument, but keep in mind that I don't know
python's C API.

worker: avoid potential partial write of pickled data
Previously, the code wrote the pickled data using os.write(). However,
os.write() can write less bytes than passed to it. To trigger the problem, the
pickled data had to be larger than 2147479552 bytes on my system.
Instead, open a file object and pass it to pickle.dump(). This also has the
advantage that it doesn’t buffer the whole pickled data in memory.
Note that the opened file must be buffered because pickle doesn’t support
unbuffered streams because unbuffered streams’ write() method might write less
bytes than passed to it (like os.write()) but pickle.dump() relies on that all
bytes are written (see https://github.com/python/cpython/issues/93050).
The side effect of using a file object and a with statement is that wfd is
explicitly closed now while it seems like before it was implicitly closed by
process exit.
