graphlog: apply file filters --patch/--stat output
When passing --patch/--stat, file filters have to be applied to generate the
correct diff or stat output:
- Without --follow, the static match object can be reused
- With --follow, the files displayed at revision X are the ancestors of
selected files at parent revision. To do this, we reproduce the ancestry
calculations done by --follow, lazily.
test-glog.t changes show that --patch output is not satisfying because renames
are reported as copies. This can probably be fixed by:
- Without --follow: compute files to display, look for renames sources and
extend the matcher to include them.
- With --follow: detect .path() transitions between parent/child filectx,
filter them using the linked changectx .removed() field and extend fcache
with them.
