dirstatemap: drop legacy method on the dirstatemap wrapper

They are no longer in use now that the Rust wrapper version of the Dirstatemap
are back in line with the Python one.

Differential Revision: https://phab.mercurial-scm.org/D11582

A new repository uses zlib storage, which doesn't need a requirement

  $ cat << EOF >> $HGRCPATH
  > [format]
  > # stabilize test accross variant
  > revlog-compression=zlib
  > EOF


  $ hg init default
  $ cd default
  $ cat .hg/requires
  dotencode
  exp-dirstate-v2 (dirstate-v2 !)
  fncache
  generaldelta
  persistent-nodemap (rust !)
  revlogv1
  sparserevlog
  store
  testonly-simplestore (reposimplestore !)

  $ touch foo
  $ hg -q commit -A -m 'initial commit with a lot of repeated repeated repeated text to trigger compression'
  $ hg debugrevlog -c | grep 0x78
      0x78 (x)  :   1 (100.00%)
      0x78 (x)  : 110 (100.00%)

  $ cd ..

Unknown compression engine to format.compression aborts

  $ hg --config format.revlog-compression=unknown init unknown
  abort: compression engines "unknown" defined by format.revlog-compression not available
  (run "hg debuginstall" to list available compression engines)
  [255]

unknown compression engine in a list with known one works fine

  $ hg --config format.revlog-compression=zlib,unknown init zlib-before-unknow
  $ hg --config format.revlog-compression=unknown,zlib init unknown-before-zlib

A requirement specifying an unknown compression engine results in bail

  $ hg init unknownrequirement
  $ cd unknownrequirement
  $ echo exp-compression-unknown >> .hg/requires
  $ hg log
  abort: repository requires features unknown to this Mercurial: exp-compression-unknown
  (see https://mercurial-scm.org/wiki/MissingRequirement for more information)
  [255]

  $ cd ..

Specifying a new format.compression on an existing repo won't introduce data
with that engine or a requirement

  $ cd default
  $ touch bar
  $ hg --config format.revlog-compression=none -q commit -A -m 'add bar with a lot of repeated repeated repeated text'

  $ cat .hg/requires
  dotencode
  exp-dirstate-v2 (dirstate-v2 !)
  fncache
  generaldelta
  persistent-nodemap (rust !)
  revlogv1
  sparserevlog
  store
  testonly-simplestore (reposimplestore !)

  $ hg debugrevlog -c | grep 0x78
      0x78 (x)  :   2 (100.00%)
      0x78 (x)  : 199 (100.00%)
  $ cd ..

#if zstd

  $ hg --config format.revlog-compression=zstd init zstd
  $ cd zstd
  $ cat .hg/requires
  dotencode
  exp-dirstate-v2 (dirstate-v2 !)
  fncache
  generaldelta
  persistent-nodemap (rust !)
  revlog-compression-zstd
  revlogv1
  sparserevlog
  store
  testonly-simplestore (reposimplestore !)

  $ touch foo
  $ hg -q commit -A -m 'initial commit with a lot of repeated repeated repeated text'

  $ hg debugrevlog -c | grep 0x28
      0x28      :  1 (100.00%)
      0x28      : 98 (100.00%)

  $ cd ..
