grab: move the initialization of pctx variable outside of if-else The pctx variable is used outside of the if-else but it was initialized under the conditional statements. Added test for the case when the initialization inside the if-else broke `hg grab --continue`.

compat: drop hack around http request handling for 4.6 The approach we used in 4.5 works again :-)

obsdiscovery: add compatibility layer to register wireproto command Mercurial core 0b18604db95e changed the way permissions are registered.

compat: pass all hgweb dispatch argument to the orig function This make use compatible with whatever changes on this side.

grab: add short version for continue and abort

obsdiscovery: include units in ui.progress() calls (issue5773)

tests: commit tests changes missing in the previous changeset (guess who forgot to amend)...

obslog: add the operation to the Obslog output The operation is helpful when debugging a case where we don't know how we ended up in this case while effect-flag are useful to understand what semantic changes happens to a changeset. Add the operation when displaying an obs-marker in the following form: `rewritten as X using amend` The other proposal is interesting but seems harder to internationalize and might requires update each time we introduce new operation: `Amended as X` Let's use the first proposal right now.

serverminitopic: attempt to fix assertion for repoview in branchmap This seems fine since we topic never impact public only caches.

compat: register a version of 'obsfatedata' template that works with 4.6 Since showlist is deprecated, let us use compatlist.
