The with-body is executed in the background process,
while the foreground process survives until the body is left
or the given timeout is exceeded. In the latter case a warning is
reported by the foreground.
Context variable is (old_id, new_id) get_process_id tuples.
An exception raised in the body is reported by the foreground
as a warning as well as propagated outside the body in the background.
In case of a warning, the foreground exits with exit code EXIT_WARNING
instead of EXIT_SUCCESS.

when entering context, set up signal handler <handler> for signal <sig>.
when leaving context, restore original signal handler.
<sig> can bei either a str when giving a signal.SIGXXX attribute name (it
won't crash if the attribute name does not exist as some names are platform
specific) or a int, when giving a signal number.
<handler> is any handler value as accepted by the signal.signal(sig, handler).

Ignore SIGINT, see also issue #6912.
Ctrl-C will send a SIGINT to both the main process (borg) and subprocesses
(e.g. ssh for remote ssh:// repos), but often we do not want the subprocess
getting killed (e.g. because it is still needed to cleanly shut down borg).
To avoid that: Popen(..., preexec_fn=ignore_sigint)

Handle typical errors raised by subprocess.Popen. Return None if an error occurred,
otherwise return the Popen object.
*cmd_line* is split using shlex (e.g. 'gzip -9' => ['gzip', '-9']).
Log messages will be prefixed with *log_prefix*; if set, it should end with a space
(e.g. log_prefix='--some-option: ').
Does not change the exit code.

Prepare the environment for a subprocess we are going to create.
:param system: True for preparing to invoke system-installed binaries,
False for stuff inside the pyinstaller environment (like borg, python).
:param env: optionally give a environment dict here. if not given, default to os.environ.
:return: a modified copy of the environment
