inno: remove w9xpopen.exe

w9xpopen.exe is a utility program shipped with Python <3.4
(https://bugs.python.org/issue14470 tracked its removal).

The program was used by subprocess to wrap invoked processes
on Windows 95 and 98 or when command.com was used in order to
work around a redirect bug.

The workaround is only used on ancient Windows versions -
versions that we shouldn't see in 2019.

While Python 2.7's subprocess module still references
w9xpopen.exe, not shipping it shouldn't matter unless we're
running an ancient version of Windows. Python will raise
an exception if w9xpopen.exe can't be found.

It's highly unlikely anyone is using current Mercurial releases
on these ancient Windows versions. So remove w9xpopen.exe
from the Inno installer.

.. bc::

   The 32-bit Windows Inno installers no longer distribute
   w9xpopen.exe. This should only impact people running
   Mercurial on Windows 95, 98, or ME.

  $ hg init

  $ echo a > a
  $ hg ci -qAm 'add a'

  $ hg init subrepo
  $ echo 'subrepo = http://example.net/libfoo' > .hgsub
  $ hg ci -qAm 'added subrepo'

  $ hg up -qC 0
  $ echo ax > a
  $ hg ci -m 'changed a'
  created new head

  $ hg up -qC 1
  $ cd subrepo
  $ echo b > b
  $ hg add b
  $ cd ..

Should fail, since there are added files to subrepo:

  $ hg merge
  abort: uncommitted changes in subrepository "subrepo"
  [255]

Deleted files trigger a '+' marker in top level repos.  Deleted files are also
noticed by `update --check` in the top level repo.

  $ hg ci -Sqm 'add b'
  $ echo change > subrepo/b

  $ hg ci -Sm 'change b'
  committing subrepository subrepo

  $ rm a
  $ hg id
  9bfe45a197d7+ tip
  $ hg sum
  parent: 4:9bfe45a197d7 tip
   change b
  branch: default
  commit: 1 deleted (clean)
  update: 1 new changesets, 2 branch heads (merge)
  phases: 5 draft

  $ hg up --check -r '.^'
  abort: uncommitted changes
  [255]
  $ hg st -S
  ! a
  $ hg up -Cq .

Test that dirty is consistent through subrepos

  $ rm subrepo/b

A deleted subrepo file is flagged as dirty, like the top level repo

  $ hg id --config extensions.blackbox= --config blackbox.dirty=True \
  > --config blackbox.track='command commandfinish'
  9bfe45a197d7+ tip
  $ cat .hg/blackbox.log
  * @9bfe45a197d7b0ab09bf287729dd57e9619c9da5+ (*)> serve --cmdserver chgunix * (glob) (chg !)
  * @9bfe45a197d7b0ab09bf287729dd57e9619c9da5+ (*)> id --config *extensions.blackbox=* --config *blackbox.dirty=True* (glob)
  * @9bfe45a197d7b0ab09bf287729dd57e9619c9da5+ (*)> id --config *extensions.blackbox=* --config *blackbox.dirty=True* exited 0 * (glob)

TODO: a deleted file should be listed as such, like the top level repo

  $ hg sum
  parent: 4:9bfe45a197d7 tip
   change b
  branch: default
  commit: (clean)
  update: 1 new changesets, 2 branch heads (merge)
  phases: 5 draft

Modified subrepo files are noticed by `update --check` and `summary`

  $ echo mod > subrepo/b
  $ hg st -S
  M subrepo/b

  $ hg up -r '.^' --check
  abort: uncommitted changes in subrepository "subrepo"
  [255]

  $ hg sum
  parent: 4:9bfe45a197d7 tip
   change b
  branch: default
  commit: 1 subrepos
  update: 1 new changesets, 2 branch heads (merge)
  phases: 5 draft

TODO: why is -R needed here?  If it's because the subrepo is treated as a
discrete unit, then this should probably warn or something.
  $ hg revert -R subrepo --no-backup subrepo/b -r .

  $ rm subrepo/b
  $ hg st -S
  ! subrepo/b

`hg update --check` notices a subrepo with a missing file, like it notices a
missing file in the top level repo.

  $ hg up -r '.^' --check
  abort: uncommitted changes in subrepository "subrepo"
  [255]

  $ hg up -r '.^' --config ui.interactive=True << EOF
  > d
  > EOF
  file 'b' was deleted in local [working copy] but was modified in other [destination].
  What do you want to do?
  use (c)hanged version, leave (d)eleted, or leave (u)nresolved? d
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

XXX: There's a difference between wdir() and '.', so there should be a status.
`hg files -S` from the top is also missing 'subrepo/b'.

  $ hg st -S
  $ hg st -R subrepo
  $ hg files -R subrepo
  [1]
  $ hg files -R subrepo -r '.'
  subrepo/b

  $ hg bookmark -r tip @other
  $ echo xyz > subrepo/c
  $ hg ci -SAm 'add c'
  adding subrepo/c
  committing subrepository subrepo
  created new head
  $ rm subrepo/c

Merge sees deleted subrepo files as an uncommitted change

  $ hg merge @other
  abort: uncommitted changes in subrepository "subrepo"
  [255]
