manifest: use 't' for tree manifest flag

We currently use 'd' to indicate that a manifest entry is a
directory. Let's switch to 't', since that's not a valid hex digit and
therefore easier to spot in the raw manifest data.

This will break any existing repos with tree manifests, but it's still
an experimental feature and there are probably only a few test repos
in existence with 'd' flags.

shelve has a help message
  $ hg shelve -h
  hg shelve [OPTION]... [FILE]...
  
  save and set aside changes from the working directory
  
      Shelving takes files that "hg status" reports as not clean, saves the
      modifications to a bundle (a shelved change), and reverts the files so
      that their state in the working directory becomes clean.
  
      To restore these changes to the working directory, using "hg unshelve";
      this will work even if you switch to a different commit.
  
      When no files are specified, "hg shelve" saves all not-clean files. If
      specific files or directories are named, only changes to those files are
      shelved.
  
      Each shelved change has a name that makes it easier to find later. The
      name of a shelved change defaults to being based on the active bookmark,
      or if there is no active bookmark, the current named branch.  To specify a
      different name, use "--name".
  
      To see a list of existing shelved changes, use the "--list" option. For
      each shelved change, this will print its name, age, and description; use "
      --patch" or "--stat" for more details.
  
      To delete specific shelved changes, use "--delete". To delete all shelved
      changes, use "--cleanup".
  
  (use "hg help -e shelve" to show help for the shelve extension)
  
  options ([+] can be repeated):
  
   -A --addremove           mark new/missing files as added/removed before
                            shelving
      --cleanup             delete all shelved changes
      --date DATE           shelve with the specified commit date
   -d --delete              delete the named shelved change(s)
   -e --edit                invoke editor on commit messages
   -l --list                list current shelves
   -m --message TEXT        use text as shelve message
   -n --name NAME           use the given name for the shelved commit
   -p --patch               show patch
   -i --interactive         interactive mode, only works while creating a shelve
      --stat                output diffstat-style summary of changes
   -I --include PATTERN [+] include names matching the given patterns
   -X --exclude PATTERN [+] exclude names matching the given patterns
      --mq                  operate on patch repository
  
  (some details hidden, use --verbose to show complete help)

shelving in an empty repo should be possible
(this tests also that editor is not invoked, if '--edit' is not
specified)

  $ HGEDITOR=cat hg shelve
  shelved as default
  0 files updated, 0 files merged, 5 files removed, 0 files unresolved

  $ hg unshelve
  unshelving change 'default'

  $ hg commit -q -m 'initial commit'

  $ hg shelve
  nothing changed
  [1]

make sure shelve files were backed up

  $ ls .hg/shelve-backup
  default.hg
  default.patch

create an mq patch - shelving should work fine with a patch applied

  $ echo n > n
  $ hg add n
  $ hg commit n -m second
  $ hg qnew second.patch

shelve a change that we will delete later

  $ echo a >> a/a
  $ hg shelve
  shelved as default
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

set up some more complex changes to shelve

  $ echo a >> a/a
  $ hg mv b b.rename
  moving b/b to b.rename/b (glob)
  $ hg cp c c.copy
  $ hg status -C
  M a/a
  A b.rename/b
    b/b
  A c.copy
    c
  R b/b

prevent some foot-shooting

  $ hg shelve -n foo/bar
  abort: shelved change names may not contain slashes
  [255]
  $ hg shelve -n .baz
  abort: shelved change names may not start with '.'
  [255]

the common case - no options or filenames

  $ hg shelve
  shelved as default-01
  2 files updated, 0 files merged, 2 files removed, 0 files unresolved
  $ hg status -C

ensure that our shelved changes exist

apply it and make sure our state is as expected

(this also tests that same timestamp prevents backups from being
removed, even though there are more than 'maxbackups' backups)

  $ f -t .hg/shelve-backup/default.hg

is difficult to decide actual order of them from same timestamp)

"hg unshelve" at REV5 implies steps below:

(1) commit changes in the working directory (REV6)
(2) unbundle shelved revision (REV7)
(3) rebase: merge REV7 into REV6 (REV6 => REV6, REV7)
(4) rebase: commit merged revision (REV8)
(5) rebase: update to REV6 (REV8 => REV6)
(6) update to REV5 (REV6 => REV5)
(7) abort transaction
