Move from blocking fork/wait logic to nonblocking fork and
g_child_watch_add.
This ensures that the Profanity main loop continues to run while an
external editor is open. So we don't loose connection and react to
pings.
We change editor handling also in vcard and muc subject editing.
In the new implementation we are launching the editor and passing a
callback which we will use once the editor exited.
We use the recently added ui_susped() and ui_resume().
To not clutter the UI we need to check whether Profanity UI is suspended
and omit drawing in this case.

Several users have reported segfaults when starting up profanity which
has OMEMO support, but OMEMO is not set up yet.
@StefanKropp has been able to reproduce this and tracked it down to
`_load_identity()` calling `omemo_known_devices_keyfile_save()`.
The latter then calls `save_keyfile()` which calls
`g_key_file_save_to_file()`. This can then fail if one of the first two
strings is NULL and won't set the `error` on return. In its error handling
`save_keyfile()` unconditionally dereferences `error` which leads to the
segfault.
Fix this and also go through the entire codebase and verify that the usage
of `GError` is done correctly.

Use a singleton `Jid` inside the connection instead of always re-creating
a `Jid` from the same string.

`data_dir` would have been leaked if directory creation failed.
`editor_argv` was leaked at some point, no idea why.

In case we're not connected yet and press Alt+c a segfault occurred
since `conn.xmpp_conn` is dereferenced while it's still `NULL`.
