journal: add share extension support

Rather than put everything into one journal file, split entries up in *shared*
and *local* entries. Working copy changes are local to a specific working copy,
so should remain local only. Other entries are shared with the source if so
configured when the share was created.

When unsharing, any shared journale entries are copied across.

Journal extension test: tests the share extension support

  $ cat >> testmocks.py << EOF
  > # mock out util.getuser() and util.makedate() to supply testable values
  > import os
  > from mercurial import util
  > def mockgetuser():
  >     return 'foobar'
  > 
  > def mockmakedate():
  >     filename = os.path.join(os.environ['TESTTMP'], 'testtime')
  >     try:
  >         with open(filename, 'rb') as timef:
  >             time = float(timef.read()) + 1
  >     except IOError:
  >         time = 0.0
  >     with open(filename, 'wb') as timef:
  >         timef.write(str(time))
  >     return (time, 0)
  > 
  > util.getuser = mockgetuser
  > util.makedate = mockmakedate

  $ hg init repo
  $ cd repo
  $ hg bookmark bm
  $ touch file0
  $ hg commit -Am 'file0 added'
  adding file0
  $ hg journal --all
  previous locations of the working copy and bookmarks:
  5640b525682e  .         commit -Am 'file0 added'
  5640b525682e  bm        commit -Am 'file0 added'

A shared working copy initially receives the same bookmarks and working copy

  $ cd ..
  $ hg share repo shared1
  updating working directory
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ cd shared1
  $ hg journal --all
  previous locations of the working copy and bookmarks:
  5640b525682e  .         share repo shared1

unless you explicitly share bookmarks

  $ cd ..
  $ hg share --bookmarks repo shared2
  updating working directory
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ cd shared2
  $ hg journal --all
  previous locations of the working copy and bookmarks:
  5640b525682e  .         share --bookmarks repo shared2
  5640b525682e  bm        commit -Am 'file0 added'

Moving the bookmark in the original repository is only shown in the repository
that shares bookmarks

  $ cd ../repo
  $ touch file1
  $ hg commit -Am "file1 added"
  adding file1
  $ cd ../shared1
  $ hg journal --all
  previous locations of the working copy and bookmarks:
  5640b525682e  .         share repo shared1
  $ cd ../shared2
  $ hg journal --all
  previous locations of the working copy and bookmarks:
  6432d239ac5d  bm        commit -Am 'file1 added'
  5640b525682e  .         share --bookmarks repo shared2
  5640b525682e  bm        commit -Am 'file0 added'

But working copy changes are always 'local'

  $ cd ../repo
  $ hg up 0
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  (leaving bookmark bm)
  $ hg journal --all
  previous locations of the working copy and bookmarks:
  5640b525682e  .         up 0
  6432d239ac5d  .         commit -Am 'file1 added'
  6432d239ac5d  bm        commit -Am 'file1 added'
  5640b525682e  .         commit -Am 'file0 added'
  5640b525682e  bm        commit -Am 'file0 added'
  $ cd ../shared2
  $ hg journal --all
  previous locations of the working copy and bookmarks:
  6432d239ac5d  bm        commit -Am 'file1 added'
  5640b525682e  .         share --bookmarks repo shared2
  5640b525682e  bm        commit -Am 'file0 added'
  $ hg up tip
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg up 0
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg journal
  previous locations of '.':
  5640b525682e  up 0
  6432d239ac5d  up tip
  5640b525682e  share --bookmarks repo shared2

Unsharing works as expected; the journal remains consistent

  $ cd ../shared1
  $ hg unshare
  $ hg journal --all
  previous locations of the working copy and bookmarks:
  5640b525682e  .         share repo shared1
  $ cd ../shared2
  $ hg unshare
  $ hg journal --all
  previous locations of the working copy and bookmarks:
  5640b525682e  .         up 0
  6432d239ac5d  .         up tip
  6432d239ac5d  bm        commit -Am 'file1 added'
  5640b525682e  .         share --bookmarks repo shared2
  5640b525682e  bm        commit -Am 'file0 added'

New journal entries in the source repo no longer show up in the other working copies

  $ cd ../repo
  $ hg bookmark newbm -r tip
  $ hg journal newbm
  previous locations of 'newbm':
  6432d239ac5d  bookmark newbm -r tip
  $ cd ../shared2
  $ hg journal newbm
  previous locations of 'newbm':
  no recorded locations

This applies for both directions

  $ hg bookmark shared2bm -r tip
  $ hg journal shared2bm
  previous locations of 'shared2bm':
  6432d239ac5d  bookmark shared2bm -r tip
  $ cd ../repo
  $ hg journal shared2bm
  previous locations of 'shared2bm':
  no recorded locations
