tests: add test about aborting content-divergence when multiple parents
This patch adds tests for --abort flag of hg evolve command when we are
resolving content-divergence which are on different parents and parent of one of
them is the gca of both of them.
The tests shows that we are doing good and we should advertise the flag during
conflicts.

Build some basic graph
----------------------
$ for x in base_a base_b base_c base_d base_e ; do
> mkcommit $x
> done
Add another branch with two heads
$ hg up 'desc(base_a)'
0 files updated, 0 files merged, 4 files removed, 0 files unresolved
$ hg branch lake
marked working directory as branch lake
(branches are permanent and global, did you want a bookmark?)
$ mkcommit lake_a
$ mkcommit lake_b
$ hg up 'desc(lake_a)'
0 files updated, 0 files merged, 1 files removed, 0 files unresolved
$ mkcommit lake_c
created new head
(consider using topic for lightweight branches. See 'hg help topic')
Add some topics
---------------
A simple topic that need rebasing
$ hg up 'desc(base_c)'
2 files updated, 0 files merged, 2 files removed, 0 files unresolved
$ hg topic baz
marked working directory as topic: baz
$ mkcommit baz_a
active topic 'baz' grew its first changeset
(see 'hg help topics' for more information)
$ mkcommit baz_b
A simple topic with unstability
$ hg up 'desc(base_d)'
1 files updated, 0 files merged, 2 files removed, 0 files unresolved
$ hg topic fuz
marked working directory as topic: fuz
$ mkcommit fuz_a
active topic 'fuz' grew its first changeset
(see 'hg help topics' for more information)
$ mkcommit fuz_b
$ mkcommit fuz_c
$ hg up 'desc(fuz_a)'
0 files updated, 0 files merged, 2 files removed, 0 files unresolved
$ hg commit --amend --message 'fuz1_a'
2 new orphan changesets
A topic with multiple heads
$ hg up 'desc(base_e)'
1 files updated, 0 files merged, 1 files removed, 0 files unresolved
$ hg topic bar
marked working directory as topic: bar
$ mkcommit bar_a
active topic 'bar' grew its first changeset
(see 'hg help topics' for more information)
$ mkcommit bar_b
$ mkcommit bar_c
$ hg up 'desc(bar_b)'
0 files updated, 0 files merged, 1 files removed, 0 files unresolved
$ mkcommit bar_d
$ mkcommit bar_e
$ hg up 'desc(bar_d)'
0 files updated, 0 files merged, 1 files removed, 0 files unresolved
$ hg commit --amend --message 'bar1_d'
1 new orphan changesets
topic 'foo' on the multi headed branch
$ hg up 'desc(lake_a)'
1 files updated, 0 files merged, 7 files removed, 0 files unresolved
$ hg topic foo
marked working directory as topic: foo
$ mkcommit foo_a
active topic 'foo' grew its first changeset
(see 'hg help topics' for more information)
$ mkcommit foo_b
