topic: add a `exp….topic.linear-merge` option to allow some oedipus

If this option is set to `from-branch`, a user can call `hg merge some-topic`
from a bare branch even if `some-topic` is a direct descendant of the current
working copy parents. This was previously denied if the changesets was on the
same branch, since the result would be an "oedipus merge".

Some user have been requesting this, and this type of merge is one of Gitlab
standard way of merging a "Merge Request". That new option will unlock issue
`heptapod#200` and make this mode available for those who wants it.

Check pick behavior regarding working copy branch (issue6089)
-------------------------------------------------------------

The branch of the picked changeset should be preserved, and the working copy updated

  $ hg init issue6089
  $ cd issue6089

  $ touch a
  $ hg add a
  $ hg ci -m 'first commit on default'

  $ hg branch foo
  marked working directory as branch foo
  (branches are permanent and global, did you want a bookmark?)
  $ touch b
  $ hg add b
  $ hg ci -m 'first commit on foo'

  $ hg up default
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ echo test > a
  $ hg ci -m 'second commit on default'
  $ hg log -G --template '{node|short}: {branch}\n' --rev 'all()+wdir()'
  o  ffffffffffff: default
  |
  @  5f07cbf7d111: default
  |
  | o  96bb2057779e: foo
  |/
  o  d03a6bcc83cd: default
  

  $ hg pick 1
  picking 1:96bb2057779e "first commit on foo"
  $ hg log --template '{branch}\n' -r tip
  foo
  $ hg branch
  foo
  $ hg log -G --template '{node|short}: {branch}\n' --rev 'all()+wdir()'
  o  ffffffffffff: foo
  |
  @  5344a77549bd: foo
  |
  o  5f07cbf7d111: default
  |
  o  d03a6bcc83cd: default
  
  $ cd ..

Check that pick doesn't drop files after conflicts occur (issue6037)
--------------------------------------------------------------------

  $ hg init issue6037
  $ cd issue6037

  $ echo apple > a
  $ hg ci -qAm 'apple'

  $ echo apricot > a
  $ echo banana > b
  $ hg ci -qAm 'apricot and banana'

  $ echo avocado > a
  $ hg ci -m 'avocado'

  $ hg glf
  @  2: avocado (a)
  |
  o  1: apricot and banana (a b)
  |
  o  0: apple (a)
  
Now let's change order of 1 and 2 using pick command

  $ hg up -r 0
  1 files updated, 0 files merged, 1 files removed, 0 files unresolved

We avoid merge conflict here just to make the test shorter

  $ hg pick -r 2 --tool :other
  picking 2:f08a1e4a33c4 "avocado"

Now we pick revision 1 that touches two files (a and b), merge conflict is expected

  $ hg pick -r 1
  picking 1:892e123ebf62 "apricot and banana"
  merging a
  warning: conflicts while merging a! (edit, then use 'hg resolve --mark')
  unresolved merge conflicts (see hg help resolve)
  [1]
  $ hg resolve -t :other a
  (no more unresolved files)
  continue: hg pick --continue
  $ hg pick --continue

Demonstrate that b was not forgotten and is definitely included in 4

  $ hg status b -A
  C b
  $ hg glf
  @  4: apricot and banana (a b)
  |
  o  3: avocado (a)
  |
  o  0: apple (a)
  
  $ cd ..
