histedit: replaces patching logic by merges

The old and fragile patching logic is replaced by smart merges (as rebase and
graft do). This should prevents some conflicts and smoother human resolution.

For this purpose the "foldchanges" function is renamed to "applychanges" and
handle a single revision only.

Prepare repo a:

  $ hg init a
  $ cd a
  $ echo a > a
  $ hg add a
  $ hg commit -m test
  $ echo first line > b
  $ hg add b

Create a non-inlined filelog:

  $ python -c 'file("data1", "wb").write("".join("%s\n" % x for x in range(10000)))'
  $ for j in 0 1 2 3 4 5 6 7 8 9; do
  >   cat data1 >> b
  >   hg commit -m test
  > done

List files in store/data (should show a 'b.d'):

  $ for i in .hg/store/data/*; do
  >   echo $i
  > done
  .hg/store/data/a.i
  .hg/store/data/b.d
  .hg/store/data/b.i

Default operation:

  $ hg clone . ../b
  updating to branch default
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ cd ../b
  $ cat a
  a
  $ hg verify
  checking changesets
  checking manifests
  crosschecking files in changesets and manifests
  checking files
  2 files, 11 changesets, 11 total revisions

Invalid dest '' must abort:

  $ hg clone . ''
  abort: empty destination path is not valid
  [255]

No update, with debug option:

#if hardlink
  $ hg --debug clone -U . ../c
  linked 8 files
  listing keys for "bookmarks"
#else
  $ hg --debug clone -U . ../c
  copied 8 files
  listing keys for "bookmarks"
#endif
  $ cd ../c
  $ cat a 2>/dev/null || echo "a not present"
  a not present
  $ hg verify
  checking changesets
  checking manifests
  crosschecking files in changesets and manifests
  checking files
  2 files, 11 changesets, 11 total revisions

Default destination:

  $ mkdir ../d
  $ cd ../d
  $ hg clone ../a
  destination directory: a
  updating to branch default
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ cd a
  $ hg cat a
  a
  $ cd ../..

Check that we drop the 'file:' from the path before writing the .hgrc:

  $ hg clone file:a e
  updating to branch default
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ grep 'file:' e/.hg/hgrc
  [1]

Check that path aliases are expanded:

  $ hg clone -q -U --config 'paths.foobar=a#0' foobar f
  $ hg -R f showconfig paths.default
  $TESTTMP/a#0 (glob)

Use --pull:

  $ hg clone --pull a g
  requesting all changes
  adding changesets
  adding manifests
  adding file changes
  added 11 changesets with 11 changes to 2 files
  updating to branch default
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg -R g verify
  checking changesets
  checking manifests
  crosschecking files in changesets and manifests
  checking files
  2 files, 11 changesets, 11 total revisions

Invalid dest '' with --pull must abort (issue2528):

  $ hg clone --pull a ''
  abort: empty destination path is not valid
  [255]

Clone to '.':

  $ mkdir h
  $ cd h
  $ hg clone ../a .
  updating to branch default
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ cd ..


*** Tests for option -u ***

Adding some more history to repo a:

  $ cd a
  $ hg tag ref1
  $ echo the quick brown fox >a
  $ hg ci -m "hacked default"
  $ hg up ref1
  1 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg branch stable
  marked working directory as branch stable
  (branches are permanent and global, did you want a bookmark?)
  $ echo some text >a
  $ hg ci -m "starting branch stable"
  $ hg tag ref2
  $ echo some more text >a
  $ hg ci -m "another change for branch stable"
  $ hg up ref2
  1 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg parents
