stream-clone: filter possible missing requirements using all supported one

The `supportedformat` requirements is missing some important requirements and it
seems better to filter out with all requirements we know, not just an
"arbitrary" subset.

The `supportedformat` set is lacking some important requirements (for example
`revlog-compression-zstd`). This is getting fixed on default (for Mercurial 6.1)

However, fixing that in 6.1 means the stream requirements sent over the wire
will contains more items. And if we don't apply this fix on older version, they
might end up complaining about lacking support for feature they actually support
for years.

This patch does not fix the deeper problem (advertised stream requirement
lacking some of them), but focus on the trivial part : Lets use the full set of
supported requirement for looking for unsupported ones.

This patch should be simple to backport to older version of Mercurial and
packager should be encouraged to do so.

This is a graft of d9017df70135 from default.

test sparse

  $ hg init myrepo
  $ cd myrepo
  $ cat > .hg/hgrc <<EOF
  > [extensions]
  > sparse=
  > strip=
  > EOF

  $ echo a > show
  $ echo x > hide
  $ hg ci -Aqm 'initial'

  $ echo b > show
  $ echo y > hide
  $ echo aa > show2
  $ echo xx > hide2
  $ hg ci -Aqm 'two'

Verify basic --include

  $ hg up -q 0
  $ hg debugsparse --include 'hide'
  $ ls -A
  .hg
  hide

Absolute paths outside the repo should just be rejected

#if no-windows
  $ hg debugsparse --include /foo/bar
  abort: paths cannot be absolute
  [255]
  $ hg debugsparse --include '$TESTTMP/myrepo/hide'

  $ hg debugsparse --include '/root'
  abort: paths cannot be absolute
  [255]
#else
TODO: See if this can be made to fail the same way as on Unix
  $ hg debugsparse --include /c/foo/bar
  abort: paths cannot be absolute
  [255]
  $ hg debugsparse --include '$TESTTMP/myrepo/hide'

  $ hg debugsparse --include '/c/root'
  abort: paths cannot be absolute
  [255]
#endif

Paths should be treated as cwd-relative, not repo-root-relative
  $ mkdir subdir && cd subdir
  $ hg debugsparse --include path
  $ hg debugsparse
  [include]
  $TESTTMP/myrepo/hide
  hide
  subdir/path
  
  $ cd ..
  $ echo hello > subdir/file2.ext
  $ cd subdir
  $ hg debugsparse --include '**.ext'  # let us test globs
  $ hg debugsparse --include 'path:abspath'  # and a path: pattern
  $ cd ..
  $ hg debugsparse
  [include]
  $TESTTMP/myrepo/hide
  hide
  path:abspath
  subdir/**.ext
  subdir/path
  
  $ rm -rf subdir

Verify commiting while sparse includes other files

  $ echo z > hide
  $ hg ci -Aqm 'edit hide'
  $ ls -A
  .hg
  hide
  $ hg manifest
  hide
  show

Verify --reset brings files back

  $ hg debugsparse --reset
  $ ls -A
  .hg
  hide
  show
  $ cat hide
  z
  $ cat show
  a

Verify 'hg debugsparse' default output

  $ hg up -q null
  $ hg debugsparse --include 'show*'

  $ hg debugsparse
  [include]
  show*
  
Verify update only writes included files

  $ hg up -q 0
  $ ls -A
  .hg
  show

  $ hg up -q 1
  $ ls -A
  .hg
  show
  show2

Verify status only shows included files

  $ touch hide
  $ touch hide3
  $ echo c > show
  $ hg status
  M show

Adding an excluded file should fail

  $ hg add hide3
  abort: cannot add 'hide3' - it is outside the sparse checkout
  (include file with `hg debugsparse --include <pattern>` or use `hg add -s <file>` to include file directory while adding)
  [255]

But adding a truly excluded file shouldn't count

  $ hg add hide3 -X hide3

Verify deleting sparseness while a file has changes fails

  $ hg debugsparse --delete 'show*'
  pending changes to 'hide'
  abort: cannot change sparseness due to pending changes (delete the files or use --force to bring them back dirty)
  [255]

Verify deleting sparseness with --force brings back files

  $ hg debugsparse --delete -f 'show*'
  pending changes to 'hide'
  $ ls -A
  .hg
  hide
  hide2
  hide3
  show
  show2
  $ hg st
  M hide
  M show
  ? hide3

Verify editing sparseness fails if pending changes

  $ hg debugsparse --include 'show*'
  pending changes to 'hide'
  abort: could not update sparseness due to pending changes
  [255]

Verify adding sparseness hides files

  $ hg debugsparse --exclude -f 'hide*'
  pending changes to 'hide'
  $ ls -A
  .hg
  hide
  hide3
  show
  show2
  $ hg st
  M show

  $ hg up -qC .
TODO: add an option to purge to also purge files outside the sparse config?
  $ hg purge --all --config extensions.purge=
  $ ls -A
  .hg
  hide
  hide3
  show
  show2
For now, manually remove the files
  $ rm hide hide3

Verify rebase temporarily includes excluded files

  $ hg rebase -d 1 -r 2 --config extensions.rebase=
  rebasing 2:b91df4f39e75 tip "edit hide"
  temporarily included 2 file(s) in the sparse checkout for merging
  merging hide
  warning: conflicts while merging hide! (edit, then use 'hg resolve --mark')
  unresolved conflicts (see 'hg resolve', then 'hg rebase --continue')
  [240]

  $ hg debugsparse
  [exclude]
  hide*
  
  Temporarily Included Files (for merge/rebase):
  hide

  $ cat hide
  <<<<<<< dest:   39278f7c08a9 - test: two
  y
  =======
  z
  >>>>>>> source: b91df4f39e75 - test: edit hide

Verify aborting a rebase cleans up temporary files

  $ hg rebase --abort --config extensions.rebase=
  cleaned up 1 temporarily added file(s) from the sparse checkout
  rebase aborted
  $ rm hide.orig

  $ ls -A
  .hg
  show
  show2

Verify merge fails if merging excluded files

  $ hg up -q 1
  $ hg merge -r 2
  temporarily included 2 file(s) in the sparse checkout for merging
  merging hide
  warning: conflicts while merging hide! (edit, then use 'hg resolve --mark')
  0 files updated, 0 files merged, 0 files removed, 1 files unresolved
  use 'hg resolve' to retry unresolved file merges or 'hg merge --abort' to abandon
  [1]
  $ hg debugsparse
  [exclude]
  hide*
  
  Temporarily Included Files (for merge/rebase):
  hide

  $ hg up -C .

Verify strip -k resets dirstate correctly

  $ hg status
  $ hg debugsparse
  [exclude]
  hide*
  
  $ hg log -r . -T '{rev}\n' --stat
  1
   hide  |  2 +-
   hide2 |  1 +
   show  |  2 +-
   show2 |  1 +
   4 files changed, 4 insertions(+), 2 deletions(-)
  
  $ hg strip -r . -k
  saved backup bundle to $TESTTMP/myrepo/.hg/strip-backup/39278f7c08a9-ce59e002-backup.hg
  $ hg status
  M show
  ? show2

Verify rebase succeeds if all changed files are in sparse checkout

  $ hg commit -Aqm "add show2"
  $ hg rebase -d 1 --config extensions.rebase=
  rebasing 2:bdde55290160 tip "add show2"
  saved backup bundle to $TESTTMP/myrepo/.hg/strip-backup/bdde55290160-216ed9c6-rebase.hg

Verify log --sparse only shows commits that affect the sparse checkout

  $ hg log -T '{rev} '
  2 1 0  (no-eol)
  $ hg log --sparse -T '{rev} '
  2 0  (no-eol)

Test status on a file in a subdir

  $ mkdir -p dir1/dir2
  $ touch dir1/dir2/file
  $ hg debugsparse -I dir1/dir2
  $ hg status
  ? dir1/dir2/file

Mix files and subdirectories, both "glob:" and unprefixed

  $ hg debugsparse --reset
  $ touch dir1/notshown
  $ hg commit -A dir1/notshown -m "notshown"
  $ hg debugsparse --include 'dir1/dir2'
  $ "$PYTHON" $TESTDIR/list-tree.py . | egrep -v '\.[\/]\.hg'

dirstate

  a   0         -1 * includedadded (glob)

Test debugdirstate --minimal where a file is not in parent manifest
but in the dirstate. This should take into account excluded files in the
manifest
  $ cp ../dirstateboth .hg/dirstate
  $ touch includedadded
  $ hg add includedadded
  $ touch excludednomanifest
  $ hg add excludednomanifest
  $ cp .hg/dirstate ../moreexcluded
  $ hg forget excludednomanifest

  $ cp ../moreexcluded .hg/dirstate
  $ hg manifest
  excluded
  included
We have files in the dirstate that are included and excluded. Some are in the
manifest and some are not.
  $ hg debugdirstate --no-dates
