commit edfb448daa6b9f9cc4fcc5e0e1c4ac2ba8c57782
Author: Ernestas Kulik <ernestask gnome org>

Implement renaming with change notifications
This is fairly bare-bones in that there is still a couple of
problems to solve before this is actually useful.
1. Rename task: error signaling? Possible solutions are:
1. Block thread on each error, fire a signal and wait for return
value.
2. Collect all errors, fire a signal, wait for return value.
3. Pass errors to the “finished” signal.
2. Although unlikely, but, in theory, the changes queue could never get
flushed, as the timer is reset with each push (a hardcoded limit can
be used, which would force a flush - sound familiar? :p).
3. Rename task (again): the “finished” signal will usually arrive before
changed files and their parents are notified, which presents a
glorious race to work around in the test executable (quitting the
main loop, namely).
There is probably something else that I forgot to mention.
