pick: register pickstate as an unfinished state

This way pickstate file will indicate that unfinished pick command needs to be
dealt with (--continue or --abort) before modifying the repo. Otherwise it
would be e.g. possible to commit during an interrupted pick and that's not
expected.

Test for the pick command

  $ cat >> $HGRCPATH <<EOF
  > [alias]
  > glog = log -G -T "{rev}:{node|short} {desc}\n"
  > glf = log -GT "{rev}: {desc} ({files})\n"
  > [extensions]
  > EOF
  $ echo "evolve=$(echo $(dirname $TESTDIR))/hgext3rd/evolve/" >> $HGRCPATH

  $ mkcommit() {
  >    echo "$1" > "$1"
  >    hg add "$1"
  >    hg ci -m "add $1"
  > }

  $ hg init repo
  $ cd repo
  $ hg help pick
  hg pick [-r] rev

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 ..
