share: add --relative flag to store a relative path to the source

Storing a relative path the source repository is useful when exporting
repositories over the network or when they're located on external
drives where the mountpoint isn't always fixed.

Currently, Mercurial interprets paths in `.hg/shared` relative to
$PWD. I suspect this is very much unintentional, and you have to
manually edit `.hg/shared` in order to trigger this behaviour.

However, on the off chance that someone might rely on it, I added a
new capability called 'relshared'. In addition, this makes earlier
versions of Mercurial fail with a graceful error.

I should note that I haven't tested this patch on Windows.

test shared clones using relative paths work

  $ mkdir thisdir
  $ hg init thisdir/orig
  $ hg share -U thisdir/orig thisdir/abs
  $ hg share -U --relative thisdir/abs thisdir/rel
  $ cat thisdir/rel/.hg/sharedpath
  ../../orig/.hg (no-eol)
  $ grep shared thisdir/*/.hg/requires
  thisdir/abs/.hg/requires:shared
  thisdir/rel/.hg/requires:shared
  thisdir/rel/.hg/requires:relshared

test that relative shared paths aren't relative to $PWD

  $ cd thisdir
  $ hg -R rel root
  $TESTTMP/thisdir/rel
  $ cd ..

now test that relative paths really are relative, survive across
renames and changes of PWD

  $ hg -R thisdir/abs root
  $TESTTMP/thisdir/abs
  $ hg -R thisdir/rel root
  $TESTTMP/thisdir/rel
  $ mv thisdir thatdir
  $ hg -R thatdir/abs root
  abort: .hg/sharedpath points to nonexistent directory $TESTTMP/thisdir/orig/.hg!

  $ hg -R thatdir/rel root
  $TESTTMP/thatdir/rel
  $ rm -r thatdir
