metadataonlyctx: don't crash when reusing the manifest with deletions
This was originally fixed by Mateusz Kwapich for the `metaedit` command in
fb-hgext with a test for the `metaedit` command. It didn't get upstreamed
because `metaedit` was not in core.
This patch fixes the crash and adds a test about `metadataonlyctx` to
avoid future regressions.

context: make parents and text optional in metadataonlyctx
The metadataonlyctx is to copy an existing context with some minor metadata
changes. If the caller only wants to change "extra", or "user", ideally it
does not have to read and pass "parents" and "text" information.
This patch makes "parents" and "text" optionally to convenient callers.

test: add more obsmarker tests for pruning scenarios
The obsfate output in cases of pruning is not ideal right now, add some tests
so have these scenarios around.
template: better prune support in obsfate
successorssets don't returns good results for pruned commit, add a workaround
for simple cases.
A proper fix would require a large rework of successorssets algorithm, I will
send a separate series for this refactoring.
template: compute dates in obsfatedate
Extract the dates from obsmarkers. Compute the min and max date from the
obsmarker range list.
template: compute user in obsfateusers
Extract, deduplicate users informations from obs markers in order to display
them.
Print all users for the moment, we might want to display users only in verbose
mode later.
template: compute verb in obsfateverb
Add a template function obsfateverb which use the markers information to
compute a better obsfate verb.
The current logic behind the obsfate verb is simple for the moment:
- If the successorsets is empty, the changeset has been pruned, for example:
Obsfate: pruned
- If the successorsets length is 1, the changeset has been rewritten without
divergence, for example:
Obsfate: rewritten as 2:
337fec4d2edc, 3:
f257fde29c7a
- If the successorsets length is more than 1, the changeset has diverged, for
example:
Obsfate: split as 2:
337fec4d2edc, 3:
f257fde29c7a
As the divergence might occurs on a subset of successors, we might see some
successors twice:
Obsfate: split as 9:
0b997eb7ceee, 5:
dd800401bd8c, 10:
eceed8f98ffc; split
as 8:
