largefiles: update largefiles even if rebase is aborted by conflict

Before this patch, largefiles in the working directory aren't updated
correctly, if rebase is aborted by conflict. This prevents users from
viewing appropriate largefiles while resolving conflicts.

While rebase, largefiles in the working directory are updated only at
successful committing in the special code path of
"lfilesrepo.commit()".

To update largefiles even if rebase is aborted by conflict, this patch
centralizes the logic of updating largefiles in the working directory
into the "mergeupdate" wrapping "merge.update".


This is a temporary way to fix with less changes. For fundamental
resolution of this kind of problems in the future, largefiles in the
working directory should be updated with other (normal) files
simultaneously while "merge.update" execution: maybe by hooking
"applyupdates".

"Action list based updating" introduced by hooking "applyupdates" will
also improve performance of updating, because it automatically
decreases target files to be checked.


Just after this patch, there are some improper things in "Case 0" code
path of "lfilesrepo.commit()":

  - "updatelfiles" invocation is redundant for rebase
  - detailed comment doesn't meet to rebase behavior

These will be resolved after the subsequent patch for transplant,
because this code path is shared with transplant.


Even though replacing "merge.update" in rebase extension by "hg.merge"
can also avoid this problem, this patch chooses centralizing the logic
into "mergeupdate", because:

  - "merge.update" invocation in rebase extension can't be directly
    replaced by "hg.merge", because:

    - rebase requires some extra arguments, which "hg.merge" doesn't
      take (e.g. "ancestor")

    - rebase doesn't require statistics information forcibly displayed
      in "hg.merge"

  - introducing "mergeupdate" can resolve also problem of some other
    code paths directly using "merge.update"

    largefiles in the working directory aren't updated regardless of
    the result of commands below, before this patch:

    - backout (for revisions other than the parent revision of the
      working directory without "--merge")

    - graft

    - histedit (for revisions other than the parent of the working
      directory


When "partial" is specified, "merge.update" doesn't update dirstate
entries for standins, even though standins themselves are updated.

In this case, "normallookup" should be used to mark largefiles as
"possibly dirty" forcibly, because applying "normal" on lfdirstate
treats them as "clean" unexpectedly.

This is reason why "normallookup=partial" is specified for
"lfcommands.updatelfiles".


This patch doesn't test "hg rebase --continue", because it doesn't
work correctly if largefiles in the working directory are modified
manually while resolving conflicts. This will be fixed in the next
step of refactoring for largefiles.

All changes of tests/*.t files other than test-largefiles-update.t in
this patch come from invoking "updatelfiles" not after but before
statistics output of "hg.update", "hg.clean" and "hg.merge".

 #
 # The strategy is to run the original manifestmerge and then process
 # the action list it outputs. There are two cases we need to deal with:
 #
 # 1. Normal file in p1, largefile in p2. Here the largefile is
 #    detected via its standin file, which will enter the working copy
 #    with a "get" action. It is not "merge" since the standin is all
 #    Mercurial is concerned with at this level -- the link to the
 #    existing normal file is not relevant here.
 #
 # 2. Largefile in p1, normal file in p2. Here we get a "merge" action
 #    since the largefile will be present in the working copy and
 #    different from the normal file in p2. Mercurial therefore
 #    triggers a merge action.
 #
 # In both cases, we prompt the user and emit new actions to either
 # remove the standin (if the normal file was kept) or to remove the
 # normal file and get the standin (if the largefile was kept). The
 # default prompt answer is to use the largefile version since it was
 # presumably changed on purpose.

 # writing the files into the working copy and lfcommands.updatelfiles
 # will update the largefiles.

 Systematic testing of merges involving largefiles:
 
 Ancestor: normal  Parent: normal=  Parent: large   result: large
 Ancestor: normal  Parent: normal2  Parent: large   result: ?
 Ancestor: large   Parent: large=   Parent: normal  result: normal
 Ancestor: large   Parent: large2   Parent: normal  result: ?
 
 All cases should try merging both ways.
 "=" means same file content.

 Pusing revision #1 causes uploading entity 89e6c98d9288, which is
 shared also by largefiles b1, b2 in revision #2 and b in revision #5.
 
 Then, entity 89e6c98d9288 is not treated as "outgoing entity" at "hg
 summary" and "hg outgoing", even though files in outgoing revision #2
 and #5 refer it.

 More rebase testing, but also test that the largefiles are downloaded from
 'default-push' when no source is specified (issue3584). (The largefile from the
 pulled revision is however not downloaded but found in the local cache.)
 Largefiles are fetched for the new pulled revision, not for existing revisions,
 rebased or not.
