obsolescence: add test for the "branch replacement" logic during push, case A2

Mercurial checks for the introduction of new heads on push. Evolution comes
into play to detect if existing branches on the server are being replaced by
some of the new one we push.

The current code for this logic is very basic (eg: issue4354) and was poorly
tested. We have a better implementation coming in the evolve extension fixing
these issues and with more serious tests coverage. In the process of upstreaming
this improved logic, we start with adding the test case that are already passing
with the current implementation. Once they are all in, we'll upstream the better
implementation and the extra test case.

See inline documentation for details about the test case added in this
changeset.

Committing only one hunk while aborting edition of hunk

- Untoggle all the hunks, go down to the second file
- unfold it
- go down to second hunk (1 for the first hunk, 1 for the first hunkline, 1 for the second hunk, 1 for the second hunklike)
- toggle the second hunk
- toggle on and off the amend mode (to check that it toggles off)
- edit the hunk and quit the editor immediately with non-zero status
- commit

Editing a hunk puts you back on that hunk when done editing (issue5041)
To do that, we change two lines in a file, pretend to edit the second line,
exit, toggle the line selected at the end of the edit and commit.
The first line should be recorded if we were put on the second line at the end
of the edit.

  $ hg update -C .
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo "foo" > x
  $ echo "hello world" >> x
  $ echo "bar" >> x
  $ cat <<EOF >testModeCommands

Testing the review option. The entire final filtered patch should show
up in the editor and be editable. We will unselect the second file and
the first hunk of the third file. During review, we will decide that
"lower" sounds better than "bottom", and the final commit should
reflect this edition.

  $ hg update -C .

Check ui.interface logic for the chunkselector

The default interface is text
  $ cp $HGRCPATH.pretest $HGRCPATH
  $ chunkselectorinterface() {
  > python <<EOF
  > from mercurial import hg, ui, parsers;\
  > repo = hg.repository(ui.ui.load(), ".");\
  > print repo.ui.interface("chunkselector")
  > EOF
  > }
  $ chunkselectorinterface
  text

If only the default is set, we'll use that for the feature, too
  $ cp $HGRCPATH.pretest $HGRCPATH
  $ cat <<EOF >> $HGRCPATH
  > [ui]
  > interface = curses
  > EOF
  $ chunkselectorinterface
  curses

It is possible to override the default interface with a feature specific
interface
  $ cp $HGRCPATH.pretest $HGRCPATH
  $ cat <<EOF >> $HGRCPATH
  > [ui]
  > interface = text
  > interface.chunkselector = curses
  > EOF

  $ chunkselectorinterface
  curses

  $ cp $HGRCPATH.pretest $HGRCPATH
  $ cat <<EOF >> $HGRCPATH
  > [ui]
  > interface = curses
  > interface.chunkselector = text
  > EOF

  $ chunkselectorinterface
  text

If a bad interface name is given, we use the default value (with a nice
error message to suggest that the configuration needs to be fixed)

  $ cp $HGRCPATH.pretest $HGRCPATH
  $ cat <<EOF >> $HGRCPATH
  > [ui]
  > interface = blah
  > EOF
  $ chunkselectorinterface
