- Replace double by single quotes for consistency

The name of the env parameter to ExecContext.run() and .sudo() is not
descriptive enough for which environment is supposed to be modified
and how, so rename and split it up as follows:
- .run(): env -> mod_env
- .sudo(): env -> mod_env_sudo and mod_env_cmd
The parameters have the following meaning:
- "mod_env*" means that the environment is modified, not replaced
- "mod_env" and "mod_env_cmd" modify the environment "cmd" runs in
- "mod_env_sudo" modifies the environment sudo runs in
Fix the fallout of the API change all over jw-pkg.

Add the following methods, meant to do the obvious:
unlink(self, path: str) -> None
erase(self, path: str) -> None
rename(self, src: str, dst: str) -> None
mktemp(self, tmpl: str, directory: bool=False) -> None
chown(self, path: str, owner: str|None=None, group: str|None=None) -> None
chmod(self, path: str, mode: int) -> None
stat(self, path: str, follow_symlinks: bool=True) -> StatResult
file_exists(self, path: str) -> bool
is_dir(self, path: str) -> bool
All methods are async and call their protected counterpart, which is
designed to be overridden. If possible, default implementations do
something meaningful, if not, they just raise plain
NotImplementedError.

Add the basic type StatResult. It is something akin to
os.stat_result, but with user and group string members instead of
st_uid and st_gid. The latter can't be expected to be stable across
remote contexts.

Pass LC_ALL="C" to _run() by default. This is necessary to be able to
parse error messages and raise FileNotFound if need be.

Don't pass mode as a string to put(). Given the multitunde of
possible string representations for numbers, some understood by
int(string, 0) and some not, there's too much room for passing
strings which are unparseable, or worse, prone to be parsed wrongly.
However, pass mode down to _put() as a string for convenience,
because that's what most _put() implementations will need to use. If
they don't, converting to int is easy from the one defined string
format.

Add the parameter "atomic" to put() / _put(). If instructs the
implementation to take extra precautions to make sure the operation
either succeeds or fails entirely, i.e. doesn't leave a broken target
file behind.

.put() has some commands to _run(), and it uses its own CallContext
for them. Since that pattern only replicates what run() does anyway,
we could just as well use run() itself with less code, so do that.

cmd_input is passed as None to _run(), which is legal, but then used
in a call to cmd_run(), which is a public API and, hence, illegal.

run_cmd() is a thin layer over the public ExecContext API, which
falls back to using a Local instance if not other ExecContext is
specified explicitly. Both the default Local context as the
subsequent call to run() should have the same idea about
interactivity, so allowing to specify it in two parameters
("interactive" and "cmd_input") is a bad idea. Remove "interactive".

This reverts commit 04fef1e67a.
Reusing AsyncSSH's connection is fine and fast, but only if it's not
combined with the AsyncRunner. See commit 67e51cf0 why it was
introduced in the first place, along with a reasoning why it may be a
bad idea. Looks like we're now reaping what we sowed.
The current plan to get this to fly is to sprinkle async / await all
over the code paths to App.os_release(). That is a lot of churn, so
postpone and revert for now to keep CI working.
