clone: make sure we warm the cache after a clone

This work around any deviciency/limitation of the clone process. In our case
this ensure the persistent nodemap exist with valid content.

Ideally, the cloning process would also do "the right thing". However since
older server will never be able to do "the right thing". The local workaround
will be necessary anyway.

I am not worried by the performance impact of this as `hg clone` is non-instant
on large repositories where is could matters. Warming the cache if they are
already correct is very fast. And if they are not already warm, this seems like
a good time to do so.

This impact various test as more cache are now warmed sooner, all the change
should be harmless.

prepare repo1

  $ hg init repo1
  $ cd repo1
  $ echo a > a
  $ hg commit -A -m'init'
  adding a

share it

  $ cd ..
  $ hg share repo1 repo2
  updating working directory
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

share shouldn't have a store dir

  $ cd repo2
  $ test -d .hg/store

  $ hg root -Tjson | sed 's|\\\\|\\|g'
  [
   {
    "hgpath": "$TESTTMP/repo2/.hg",
    "reporoot": "$TESTTMP/repo2",
    "storepath": "$TESTTMP/repo1/.hg/store"
   }
  ]

share shouldn't have a full cache dir, original repo should

  $ hg branches
  default                        0:d3873e73d99e
  $ hg tags
  tip                                0:d3873e73d99e
  $ test -d .hg/cache
  [1]
  $ ls -1 .hg/wcache || true
  checkisexec (execbit !)
  checklink (symlink !)
  checklink-target (symlink !)
  manifestfulltextcache (reporevlogstore !)
  $ ls -1 ../repo1/.hg/cache
  branch2-served
  rbc-names-v1
  rbc-revs-v1
  tags2-visible

Cloning a shared repo should pick up the full cache dir on the other hand.

  $ hg clone . ../repo2-clone
  updating to branch default
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ ls -1 ../repo2-clone/.hg/cache
  branch2-base

Some sed versions appends newline, some don't, and some just fails

  $ cat .hg/sharedpath; echo
  $TESTTMP/repo1/.hg

trailing newline on .hg/sharedpath is ok
  $ hg tip -q

  $ echo '' >> .hg/sharedpath
  $ cat .hg/sharedpath
  $TESTTMP/repo1/.hg
  $ hg tip -q

test shared clones using relative paths work

  $ hg share -U --relative thisdir/abs thisdir/rel

  $ grep shared thisdir/*/.hg/requires
  thisdir/abs/.hg/requires:shared

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

  $ cd thisdir
  $ hg -R rel root

  $ cd ..

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

  $ hg -R thisdir/abs root

  $ mv thisdir thatdir
  $ hg -R thatdir/abs root
