import-checker: allow relative import a module being checked

This would make the checker more friendly for 3rd-party code. For example,

In remotefilelog/x.py, it may have:

    from . import shallowutils

That could trigger "relative import of stdlib module" if
"remotefilelog" was installed in the system. If the module being checked
conflicts with the system module, it makes sense to not treat that module as
system module. This patch makes it so.

  $ hg init repo0
  $ cd repo0

Empty repo / no checkout results in error

  $ hg show stack
  abort: stack view only available when there is a working directory
  [255]

Stack displays single draft changeset as root revision

  $ echo 0 > foo
  $ hg -q commit -A -m 'commit 0'
  $ hg show stack
    @  9f171 commit 0

Stack displays multiple draft changesets

  $ echo 1 > foo
  $ hg commit -m 'commit 1'
  $ echo 2 > foo
  $ hg commit -m 'commit 2'
  $ echo 3 > foo
  $ hg commit -m 'commit 3'
  $ echo 4 > foo
  $ hg commit -m 'commit 4'
  $ hg show stack
    @  2737b commit 4
    o  d1a69 commit 3
    o  128c8 commit 2
    o  181cc commit 1
    o  9f171 commit 0

Public parent of draft base is displayed, separated from stack

  $ hg phase --public -r 0
  $ hg show stack
    @  2737b commit 4
    o  d1a69 commit 3
    o  128c8 commit 2
    o  181cc commit 1
   /   (stack base)
  o  9f171 commit 0

  $ hg phase --public -r 1
  $ hg show stack
    @  2737b commit 4
    o  d1a69 commit 3
    o  128c8 commit 2
   /   (stack base)
  o  181cc commit 1

Draft descendants are shown

  $ hg -q up 2
  $ hg show stack
    o  2737b commit 4
    o  d1a69 commit 3
    @  128c8 commit 2
   /   (stack base)
  o  181cc commit 1

  $ hg -q up 3
  $ hg show stack
    o  2737b commit 4
    @  d1a69 commit 3
    o  128c8 commit 2
   /   (stack base)
  o  181cc commit 1

working dir on public changeset should display special message

  $ hg -q up 1
  $ hg show stack
  (empty stack; working directory parent is a published changeset)

Branch point in descendants displayed at top of graph

  $ hg -q up 3
  $ echo b > foo
  $ hg commit -m 'commit 5 (new dag branch)'
  created new head
  $ hg -q up 2
  $ hg show stack
   \ /  (multiple children)
    |
    o  d1a69 commit 3
    @  128c8 commit 2
   /   (stack base)
  o  181cc commit 1

  $ cd ..

Base is stopped at merges

  $ hg init merge-base
  $ cd merge-base
  $ echo 0 > foo
  $ hg -q commit -A -m initial
  $ echo h1 > foo
  $ hg commit -m 'head 1'
  $ hg -q up 0
  $ echo h2 > foo
  $ hg -q commit -m 'head 2'
  $ hg phase --public -r 0:tip
  $ hg -q up 1
  $ hg merge -t :local 2
  0 files updated, 1 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)
  $ hg commit -m 'merge heads'

TODO doesn't yet handle case where wdir is a draft merge

  $ hg show stack
    @  8ee90 merge heads
   /   (stack base)
  o  59478 head 1

  $ echo d1 > foo
  $ hg commit -m 'draft 1'
  $ echo d2 > foo
  $ hg commit -m 'draft 2'

  $ hg show stack
    @  430d5 draft 2
    o  787b1 draft 1
   /   (stack base)
  o  8ee90 merge heads

  $ cd ..

Now move on to stacks when there are more commits after the base branchpoint

  $ hg init public-rebase
  $ cd public-rebase
  $ echo 0 > foo
  $ hg -q commit -A -m 'base'
  $ hg phase --public -r .
  $ echo d1 > foo
  $ hg commit -m 'draft 1'
  $ echo d2 > foo
  $ hg commit -m 'draft 2'
  $ hg -q up 0
  $ echo 1 > foo
  $ hg commit -m 'new 1'
  created new head
  $ echo 2 > foo
  $ hg commit -m 'new 2'
  $ hg -q up 2

Newer draft heads don't impact output

  $ hg show stack
    @  eaffc draft 2
    o  2b218 draft 1
   /   (stack base)
  o  b66bb base

Newer public heads are rendered

  $ hg phase --public -r '::tip'

  $ hg show stack
    o  baa4b new 2
   /    (2 commits ahead)
  :
  :    (stack head)
  : @  eaffc draft 2
  : o  2b218 draft 1
  :/   (stack base)
  o  b66bb base

If rebase is available, we show a hint how to rebase to that head

  $ hg --config extensions.rebase= show stack
    o  baa4b new 2
   /    (2 commits ahead; hg rebase --source 2b218 --dest baa4b)
  :
  :    (stack head)
  : @  eaffc draft 2
  : o  2b218 draft 1
  :/   (stack base)
  o  b66bb base

Similar tests but for multiple heads

  $ hg -q up 0
  $ echo h2 > foo
  $ hg -q commit -m 'new head 2'
  $ hg phase --public -r .
  $ hg -q up 2

  $ hg show stack
    o  baa4b new 2
   /    (2 commits ahead)
  : o  9a848 new head 2
  :/    (1 commits ahead)
  :
  :    (stack head)
  : @  eaffc draft 2
  : o  2b218 draft 1
  :/   (stack base)
  o  b66bb base

  $ hg --config extensions.rebase= show stack
    o  baa4b new 2
   /    (2 commits ahead; hg rebase --source 2b218 --dest baa4b)
  : o  9a848 new head 2
  :/    (1 commits ahead; hg rebase --source 2b218 --dest 9a848)
  :
  :    (stack head)
  : @  eaffc draft 2
  : o  2b218 draft 1
  :/   (stack base)
  o  b66bb base
