cmdserver: add option to not exit from message loop on SIGINT
Sending SIGINT to server is the only way to interrupt a command running in
command-server process. SIGINT will be caught at dispatch.dispatch() if
we're lucky. Otherwise it will terminate the serer process. This is
fundamentally unreliable as signals are delivered asynchronously.
"cmdserver.shutdown-on-interrupt=False" mitigate the issue by making the
server basically block SIGINT.

pycompat: remove pycompat.{stdin,stdout,stderr}
All users have been changed to use procutil.{stdin,stdout,stderr}, which provide
consistent behavior across platforms and Python versions.

pycompat: change users of pycompat.{stdin,stdout,stderr} to use procutil.std*
On Python 3, pycompat.{stdin,stdout,stderr} are usually block-buffered even if
connected to a TTY. procutil.{stdin,stdout,stderr} provide consistent behavior
across platforms and Python versions.

rhg: add a limited `rhg root` subcommand
Clap has been choosen for argument parsing for the following reasons:
- it's a wildly used and maintained crate
- it can deal with OS encoding making it suitable for any encoding
- it supports nonambiguous prefix matching as already available in hg
- it will soon allow for structopts-style declarative pattern instead of the
currently used builder pattern

rhg: add RootCommand using hg-core FindRoot operation to prepare `hg root`
The println macro is not used to avoid string usage.
Dealing only with bytes allows us to be compatible with any encoding
and not just UTF8.
Later on, format macro will be made to have more readable code.

procutil: make mercurial.utils.procutil.stderr unbuffered
For most Mercurial code, it doesn’t make a difference, as the ui object flushes
stderr explicitly (after the change, we could get rid of the explicit flush).
One example where it makes a observable difference is mercurial.util.timed().
Without the patch, the time is not immediately shown on Python 3. With the
patch, it’s shown immediately on all Python versions and platforms.

procutil: make stdout line-buffered on Windows if connected to TTY
Windows doesn’t support line buffering. Previously, we worked around that by
setting the stream unbuffered. Instead, we can use our own line buffering we
already use on Python 3.

procutil: move assignments closer to reassignments
Doing reassignments is an anti-pattern IMHO, but I see how it makes sense here.
When first looking at this code after jumping here with ctags, I missed the
fact that stdout was reassigned. To make the code clearer, the assignments
should be as close as possible to the reassignments.

There’s nothing Python 3-only about LineBufferedWrapper. In the future, we may
want to use it on Windows, to work around missing line-buffering support.

me.

cleanup: use any() instead of checking truthiness of temporary list
It was not immediately obvious to me, when first seeing this, why a list was
created. It needed a second look to understand that the purpose was to check
whether the condition is true for any of the parents. Using any() for that is
clearer.

chg: suppress OSError in _restoreio() and add some logging (issue6330)
According to issue6330, running chg on heavy loaded systems can lead to
following error:
```
Traceback (most recent call last):
File "path-to-hg/mercurial/commandserver.py", line 650, in _acceptnewconnection
self._runworker(conn)
File "path-to-hg/mercurial/commandserver.py", line 701, in _runworker

File "path-to-hg/mercurial/chgserver.py", line 444, in _restoreio
os.dup2(fd, fp.fileno())
OSError: [Errno 16] Device or resource busy
```
[man dup2] indicates that, on Linux, EBUSY comes from a race condition
between open() and dup2().
However it's not clear why open() race occurred for newfd=stdin/out/err.
We suppress the OSError in _restoreio() since the forked worker process will
finish anyway and add some logging.
Thanks to Mitchell Plamann for a detailed bug description and Yuya Nishihara for
suggesting the fix.
