localrepo: support writing shared file (API)

Now that we can create a shared repository via creation options, we
can handle other special actions related to share at repo creation time
as well.

One of the things we do after creating a shared repository is write
out a .hg/shared file containing the list of additional things to
share. Of which only "bookmarks" is supported.

We add a creation option to hold the set of additional items to
share. If items are defined, we write out the .hg/shared file at
repo creation time.

As part of this, we no longer hold the repo lock when writing the
file. I'm pretty sure we don't care about the tiny race condition
window. I'm also pretty sure the reason we used the lock was because
the vfs auditor on the repo instance complained otherwise. Since the
repo creation code doesn't have an audited vfs, we don't need to
appease it.

Because we no longer need to tell the post share hook what items
are shared, the "bookmarks" argument to that function has been
dropped, incurring an API change.

test that a commit clears the merge state.

  $ hg init repo
  $ cd repo

  $ echo foo > file1
  $ echo foo > file2
  $ hg commit -Am 'add files'
  adding file1
  adding file2

  $ echo bar >> file1
  $ echo bar >> file2
  $ hg commit -Am 'append bar to files'

create a second head with conflicting edits

  $ hg up -C 0
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo baz >> file1
  $ echo baz >> file2
  $ hg commit -Am 'append baz to files'
  created new head

create a third head with no conflicting edits
  $ hg up -qC 0
  $ echo foo > file3
  $ hg commit -Am 'add non-conflicting file'
  adding file3
  created new head

failing merge

  $ hg up -qC 2
  $ hg merge --tool=internal:fail 1
  0 files updated, 0 files merged, 0 files removed, 2 files unresolved
  use 'hg resolve' to retry unresolved file merges or 'hg merge --abort' to abandon
  [1]

resolve -l should contain unresolved entries

  $ hg resolve -l
  U file1
  U file2

  $ hg resolve -l --no-status

  file2

resolving an unknown path should emit a warning, but not for -l

  $ hg resolve -m does-not-exist
  arguments do not match paths that need resolving
  $ hg resolve -l does-not-exist

tell users how they could have used resolve

  $ mkdir nested
  $ cd nested
  $ hg resolve -m file1
  arguments do not match paths that need resolving
  (try: hg resolve -m path:file1)
  $ hg resolve -m file1 filez
  arguments do not match paths that need resolving

  $ hg resolve -m path:file1 path:filez
  $ hg resolve -l
  R file1
  U file2
  $ hg resolve --re-merge filez file2
  arguments do not match paths that need resolving
  (try: hg resolve --re-merge path:filez path:file2)
  $ hg resolve -m filez file2
  arguments do not match paths that need resolving
  (try: hg resolve -m path:filez path:file2)
  $ hg resolve -m path:filez path:file2
