merge: use labels in subrepo merge

This is the last place that doesn't respect conflict labels in merge output.
Teach subrepos to use subrepo merge output too.

     The merge state is stored on disk when needed. Two files are used: one with
     an old format (version 1), and one with a new format (version 2). Version 2
     stores a superset of the data in version 1, including new kinds of records
     in the future. For more about the new format, see the documentation for
     `_readrecordsv2`.
 
     Each record can contain arbitrary content, and has an associated type. This
     `type` should be a letter. If `type` is uppercase, the record is mandatory:
     versions of Mercurial that don't support it should abort. If `type` is
     lowercase, the record can be safely ignored.
 
     Currently known records:
 
     L: the node of the "local" part of the merge (hexified version)
     O: the node of the "other" part of the merge (hexified version)
     F: a file to be merged entry
     C: a change/delete or delete/change conflict
     D: a file that the external merge driver will merge internally
        (experimental)
     m: the external merge driver defined for this merge plus its run state
        (experimental)
     f: a (filename, dictonary) tuple of optional values for a given file
     X: unsupported mandatory record type (used in tests)
     x: unsupported advisory record type (used in tests)
     l: the labels for the parts of the merge.
 
     Merge driver run states (experimental):
     u: driver-resolved files unmarked -- needs to be run next time we're about
        to resolve or commit
     m: driver-resolved files marked -- only needs to be run before commit
     s: success/skipped -- does not need to be run any more

 Test that update also updates the lfdirstate of 'unsure' largefiles after
 hashing them:
 
 The previous operations will usually have left us with largefiles with a mtime
 within the same second as the dirstate was written.
 The lfdirstate entries will thus have been written with an invalidated/unset
 mtime to make sure further changes within the same second is detected.
 We will however occasionally be "lucky" and get a tick between writing
 largefiles and writing dirstate so we get valid lfdirstate timestamps. The
 following verification is thus disabled but can be verified manually.
 
 #if false
   $ hg debugdirstate --large --nodate
   n 644          7 unset               large1
   n 644         13 unset               large2
 #endif
 
 Wait to make sure we get a tick so the mtime of the largefiles become valid.
 
   $ sleep 1
 
 A linear merge will update standins before performing the actual merge. It will
 do a lfdirstate status walk and find 'unset'/'unsure' files, hash them, and
 update the corresponding standins.
 Verify that it actually marks the clean files as clean in lfdirstate so
 we don't have to hash them again next time we update.

 Test case where subversion would fail to update the subrepo because there
 are unknown directories being replaced by tracked ones (happens with rebase).

 Modify one of the externals to point to a different path so we can
 test having obstructions when switching branches on checkout:
   $ hg checkout tip
   0 files updated, 0 files merged, 0 files removed, 0 files unresolved
   $ echo "obstruct =        [svn]       $SVNREPOURL/externals" >> .hgsub
   $ svn co -r5 --quiet "$SVNREPOURL"/externals obstruct
   $ hg commit -m 'Start making obstructed working copy'
   $ hg book other
   $ hg co -r 'p1(tip)'
   2 files updated, 0 files merged, 0 files removed, 0 files unresolved
   (leaving bookmark other)
   $ echo "obstruct =        [svn]       $SVNREPOURL/src" >> .hgsub
   $ svn co -r5 --quiet "$SVNREPOURL"/src obstruct
   $ hg commit -m 'Other branch which will be obstructed'
   created new head
 
 Switching back to the head where we have another path mapped to the
 same subrepo should work if the subrepo is clean.
   $ hg co other
   A    *obstruct/other (glob)
   Checked out revision 1.
   2 files updated, 0 files merged, 0 files removed, 0 files unresolved
   (activating bookmark other)
 
 This is surprising, but is also correct based on the current code:
   $ echo "updating should (maybe) fail" > obstruct/other
   $ hg co tip
   abort: uncommitted changes
   (commit or update --clean to discard changes)
   [255]
 
 Point to a Subversion branch which has since been deleted and recreated
 First, create that condition in the repository.

 Test behavior of add for explicit path in subrepo:
   $ cd ..
   $ hg init explicit
   $ cd explicit
   $ echo s = s > .hgsub
   $ hg add .hgsub
   $ hg init s
   $ hg ci -m0
 Adding with an explicit path in a subrepo adds the file
   $ echo c1 > f1
   $ echo c2 > s/f2
   $ hg st -S
   ? f1
   ? s/f2
   $ hg add s/f2
   $ hg st -S
   A s/f2
   ? f1
   $ hg ci -R s -m0
   $ hg ci -Am1
   adding f1
 Adding with an explicit path in a subrepo with -S has the same behavior
   $ echo c3 > f3
   $ echo c4 > s/f4
   $ hg st -S
   ? f3
   ? s/f4
   $ hg add -S s/f4
   $ hg st -S
   A s/f4
   ? f3
   $ hg ci -R s -m1
   $ hg ci -Ama2
   adding f3
 Adding without a path or pattern silently ignores subrepos
   $ echo c5 > f5
   $ echo c6 > s/f6
   $ echo c7 > s/f7
   $ hg st -S
   ? f5
   ? s/f6
   ? s/f7
   $ hg add
   adding f5
   $ hg st -S
   A f5
   ? s/f6
   ? s/f7
   $ hg ci -R s -Am2
   adding f6
   adding f7
   $ hg ci -m3
 Adding without a path or pattern with -S also adds files in subrepos
   $ echo c8 > f8
   $ echo c9 > s/f9
   $ echo c10 > s/f10
   $ hg st -S
   ? f8
   ? s/f10
   ? s/f9
   $ hg add -S
   adding f8
   adding s/f10 (glob)
   adding s/f9 (glob)
   $ hg st -S
   A f8
   A s/f10
   A s/f9
   $ hg ci -R s -m3
   $ hg ci -m4
 Adding with a pattern silently ignores subrepos
   $ echo c11 > fm11
   $ echo c12 > fn12
   $ echo c13 > s/fm13
   $ echo c14 > s/fn14
   $ hg st -S
   ? fm11
   ? fn12
   ? s/fm13
   ? s/fn14
   $ hg add 'glob:**fm*'
   adding fm11
   $ hg st -S
   A fm11
   ? fn12
   ? s/fm13
   ? s/fn14
   $ hg ci -R s -Am4
   adding fm13
   adding fn14
   $ hg ci -Am5
   adding fn12
 Adding with a pattern with -S also adds matches in subrepos
   $ echo c15 > fm15
   $ echo c16 > fn16
   $ echo c17 > s/fm17
   $ echo c18 > s/fn18
   $ hg st -S
   ? fm15
   ? fn16
   ? s/fm17
   ? s/fn18
   $ hg add -S 'glob:**fm*'
   adding fm15
   adding s/fm17 (glob)
   $ hg st -S
   A fm15
   A s/fm17
   ? fn16
   ? s/fn18
   $ hg ci -R s -Am5
   adding fn18
   $ hg ci -Am6
   adding fn16
 
 Test behavior of forget for explicit path in subrepo:
 Forgetting an explicit path in a subrepo untracks the file
   $ echo c19 > s/f19
   $ hg add s/f19
   $ hg st -S
   A s/f19
   $ hg forget s/f19
   $ hg st -S
   ? s/f19
   $ rm s/f19
