contrib: add a script for adding vendored type stubs to typeshed

I really hate this, but pytype doesn't support PEP 561 and doesn't seem to have
the equivalent of `MYPYPATH` to point to custom stubs.  Ignoring the vendored
stubs isn't necessarily harmful, but pytype has been choking on the vendored
attr package after pytype 2022.03.29 with errors like this:

    File "/mnt/c/Users/Matt/hg/mercurial/linelog.py", line 52, in __iter__: Built-in function iter was called with the wrong arguments [wrong-arg-types]
             Expected: (collection: bytearray)
      Actually passed: (collection: mercurial.thirdparty.attr._make._CountingAttr)

    File "/mnt/c/Users/Matt/hg/mercurial/dirstateutils/v2.py", line 143, in pack: Built-in function len was called with the wrong arguments [wrong-arg-types]
             Expected: (obj: Sized)

    File "/mnt/c/Users/Matt/hg/mercurial/util.py", line 2817, in go: unsupported operand type(s) for /: 'count: mercurial.thirdparty.attr._make._CountingAttr' and 'float: float' [unsupported-operands]

This is essentially the same hack we've been using in TortoiseHg to add the
vendored PyQt5 stubs.  What I don't understand is pytype *still* generates *.pyi
files under .pytype/pyi/mercurial/thirdparty/attr, even when the package is
explicitly ignored in the pytype command line args.  But it avoids the errors,
which means we aren't stuck on pytype==2022.03.29.

Prepare parent repo
-------------------

  $ hg init r
  $ cd r

  $ echo a > a
  $ hg ci -Am0
  adding a

Link first subrepo
------------------

  $ echo 's = s' >> .hgsub
  $ hg add .hgsub
  $ hg init s

amend without .hgsub

  $ hg amend s
  abort: can't commit subrepos without .hgsub
  [255]

amend with subrepo

  $ hg amend
  saved backup bundle to * (glob) (obsstore-off !)
  $ hg status --change .
  A .hgsub
  A .hgsubstate
  A a
  $ cat .hgsubstate
  0000000000000000000000000000000000000000 s

Update subrepo
--------------

add new commit to be amended

  $ echo a >> a
  $ hg ci -m1

amend with dirty subrepo

  $ echo a >> s/a
  $ hg add -R s
  adding s/a
  $ hg amend
  abort: uncommitted changes in subrepository "s"
  (use --subrepos for recursive commit)
  [255]

amend with modified subrepo

  $ hg ci -R s -m0
  $ hg amend
  saved backup bundle to * (glob) (obsstore-off !)
  $ hg status --change .
  M .hgsubstate
  M a
  $ cat .hgsubstate
  f7b1eb17ad24730a1651fccd46c43826d1bbc2ac s

revert subrepo change

  $ hg up -R s -q null
  $ hg amend
  saved backup bundle to * (glob) (obsstore-off !)
  $ hg status --change .
  M a

Link another subrepo
--------------------

add new commit to be amended

  $ echo b >> b
  $ hg ci -qAm2

also checks if non-subrepo change is included

  $ echo a >> a

amend with another subrepo

  $ hg init t
  $ echo b >> t/b
  $ hg ci -R t -Am0
  adding b
  $ echo 't = t' >> .hgsub
  $ hg amend
  saved backup bundle to * (glob) (obsstore-off !)
  $ hg status --change .
  M .hgsub
  M .hgsubstate
  M a
  A b
  $ cat .hgsubstate

  bfb1a4fb358498a9533dabf4f2043d94162f1fcd t

Unlink one subrepo
------------------

add new commit to be amended

  $ echo a >> a
  $ hg ci -m3

  $ echo 't = t' > .hgsub

--interactive won't silently ignore dirty subrepos

  $ echo modified > t/b
  $ hg amend --interactive --config ui.interactive=True
  abort: uncommitted changes in subrepository "t"
  [255]
  $ hg amend --interactive --config ui.interactive=True --config ui.commitsubrepos=True
  abort: uncommitted changes in subrepository "t"
  [255]

  $ hg -R t revert -q --all --no-backup

amend with one subrepo dropped

  $ hg amend
  saved backup bundle to * (glob) (obsstore-off !)
  $ hg status --change .
  M .hgsub
  M .hgsubstate
  M a
  $ cat .hgsubstate
  bfb1a4fb358498a9533dabf4f2043d94162f1fcd t

Unlink subrepos completely
--------------------------

add new commit to be amended

  $ echo a >> a
  $ hg ci -m3

amend with .hgsub removed

  $ hg rm .hgsub
  $ hg amend
  saved backup bundle to * (glob) (obsstore-off !)
  $ hg status --change .
  M a
  R .hgsub
  R .hgsubstate

broken repositories will refuse to push

#if obsstore-off
  $ hg up -q -C 2
#else
  $ hg up -q -C 6
#endif
  $ echo c >> t/b
  $ hg amend -q -R t

  $ hg init ../dest
  $ hg init ../dest/t
  $ hg init ../dest/s
  $ hg push -q ../dest
  abort: subrepo 't' is hidden in revision 04aa62396ec6 (obsstore-on !)
