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.

Shelve and unshelve unknown files. For the purposes of unshelve, a shelved
unknown file is the same as a shelved added file, except that it will be in
unknown state after unshelve if and only if it was either absent or unknown
before the unshelve operation.

  $ hg init unknowns
  $ cd unknowns

The simplest case is if I simply have an unknown file that I shelve and unshelve

  $ echo unknown > unknown
  $ hg status
  ? unknown
  $ hg shelve --unknown
  shelved as default
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg status
  $ hg unshelve
  unshelving change 'default'
  $ hg status
  ? unknown
  $ rm unknown

If I shelve, add the file, and unshelve, does it stay added?

  $ echo unknown > unknown
  $ hg shelve -u
  shelved as default
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg status
  $ touch unknown
  $ hg add unknown
  $ hg status
  A unknown
  $ hg unshelve
  unshelving change 'default'
  temporarily committing pending changes (restore with 'hg unshelve --abort')
  rebasing shelved changes
  merging unknown
  $ hg status
  A unknown
  $ hg forget unknown
  $ rm unknown

And if I shelve, commit, then unshelve, does it become modified?

  $ echo unknown > unknown
  $ hg shelve -u
  shelved as default
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg status
  $ touch unknown
  $ hg add unknown
  $ hg commit -qm "Add unknown"
  $ hg status
  $ hg unshelve
  unshelving change 'default'
  rebasing shelved changes
  merging unknown
  $ hg status
  M unknown
  $ hg remove --force unknown
  $ hg commit -qm "Remove unknown"

  $ cd ..

We expects that non-bare shelve keeps newly created branch in
working directory.

  $ hg init shelve-preserve-new-branch
  $ cd shelve-preserve-new-branch
  $ echo "a" >> a
  $ hg add a
  $ echo "b" >> b
  $ hg add b
  $ hg commit -m "ab"
  $ echo "aa" >> a
  $ echo "bb" >> b
  $ hg branch new-branch
  marked working directory as branch new-branch
  (branches are permanent and global, did you want a bookmark?)
  $ hg status
  M a
  M b
  $ hg branch
  new-branch
  $ hg shelve a
  shelved as default
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg branch
  new-branch
  $ hg status
  M b
  $ touch "c" >> c
  $ hg add c
  $ hg status
  M b
  A c
  $ hg shelve --exclude c
  shelved as default-01
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg branch
  new-branch
  $ hg status
  A c
  $ hg shelve --include c
  shelved as default-02
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg branch
  new-branch
  $ hg status
  $ echo "d" >> d
  $ hg add d
  $ hg status
  A d

We expect that bare-shelve will not keep branch in current working directory.

  $ hg shelve
  shelved as default-03
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg branch
  default
  $ cd ..

When i shelve commit on newly created branch i expect
that after unshelve newly created branch will be preserved.

  $ hg init shelve_on_new_branch_simple
  $ cd shelve_on_new_branch_simple
  $ echo "aaa" >> a
  $ hg commit -A -m "a"
  adding a
  $ hg branch

  $ hg branch test
  marked working directory as branch test
  (branches are permanent and global, did you want a bookmark?)
  $ echo "bbb" >> a
  $ hg status
  M a
  $ hg shelve
  shelved as default
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg branch

  $ echo "bbb" >> b
  $ hg status
  ? b
  $ hg unshelve
  unshelving change 'default'
  marked working directory as branch test
  $ hg status
  M a
  ? b
  $ hg branch
  test
  $ cd ..

When i shelve commit on newly created branch, make
some changes, unshelve it and running into merge
conflicts i expect that after fixing them and
running unshelve --continue newly created branch
will be preserved.

  $ hg init shelve_on_new_branch_conflict
  $ cd shelve_on_new_branch_conflict
  $ echo "aaa" >> a
  $ hg commit -A -m "a"

  $ rm a.orig
  $ hg resolve --mark a

  continue: hg unshelve --continue
  $ hg continue

  unshelve of 'default' complete
  $ cat a
  aaabbbccc
  $ hg status
  M a
  $ hg branch
  test
  $ hg commit -m "test-commit"

When i shelve on test branch, update to default branch
and unshelve i expect that it will not preserve previous
test branch.

  $ echo "xxx" > b
  $ hg add b
  $ hg shelve
  shelved as test
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg update -r 7049e48789d7

  $ hg unshelve
  unshelving change 'test'
  rebasing shelved changes
  $ hg status
  A b
  $ hg branch
  default
  $ cd ..

When i unshelve resulting in merge conflicts and makes saved
file shelvedstate looks like in previous versions in
mercurial(without restore branch information in 7th line) i
expect that after resolving conflicts and successfully
running 'shelve --continue' the branch information won't be
restored and branch will be unchanged.

shelve on new branch, conflict with previous shelvedstate

  $ hg init conflict
  $ cd conflict
  $ echo "aaa" >> a
  $ hg commit -A -m "a"

Removing restore branch information from shelvedstate file(making it looks like
in previous versions) and running unshelve --continue

  $ cp .hg/shelvedstate .hg/shelvedstate_old
  $ cat .hg/shelvedstate_old | grep -v 'branchtorestore' > .hg/shelvedstate

  $ echo "aaabbbccc" > a
  $ rm a.orig
  $ hg resolve --mark a
  (no more unresolved files)
  continue: hg unshelve --continue

#if continuecommand
  $ hg continue --dry-run

#endif

  $ hg continue
  unshelve of 'default' complete
  $ cat a
  aaabbbccc
  $ hg status

  $ hg branch

  $ cd ..

On non bare shelve the branch information shouldn't be restored

  $ hg init bare_shelve_on_new_branch
  $ cd bare_shelve_on_new_branch
