templates: add filter to reverse list
The filter supports only lists because for lists, it’s straightforward to
implement. Reversing text doesn’t seem very useful and is hard to implement.
Reversing the bytes would break multi-bytes encodings. Reversing the code
points would break characters consisting of multiple code points. Reversing
graphemes is non-trivial without using a library not included in the standard
library.

Check local clone
==================
The logic is close enough of uncompressed.
This is present here to reuse the testing around file with "special" names.
$ hg clone server local-clone
updating to branch default
1088 files updated, 0 files merged, 0 files removed, 0 files unresolved
Check that the clone went well
$ hg verify -R local-clone
checking changesets
checking manifests
crosschecking files in changesets and manifests
checking files
checked 3 changesets with 1088 changes to 1088 files
Check uncompressed
==================
Cannot stream clone when server.uncompressed is set
