rust-filepatterns: match exact `rootglob`s with a `HashSet`, not in the regex

This optimization yields some very interesting results in `rootglob`-heavy
repositories.

I build a test repository of the following structure:

```
root
    /<uuid>/build/empty_file
    ... repeat for 4000 entries
```

and a `.hgignore` containing the corresponding 4000 `rootglob` entries pointing
to all `build/` folders.

Rust+c `hg status` goes from 350ms down to 110ms.

Failed qimport of patches from files should cleanup by recording successfully
imported patches in series file.

  $ echo "[extensions]" >> $HGRCPATH
  $ echo "mq=" >> $HGRCPATH
  $ hg init repo
  $ cd repo
  $ echo a > a
  $ hg ci -Am'add a'
  adding a
  $ cat >b.patch<<EOF
  > diff --git a/a b/a
  > --- a/a
  > +++ b/a
  > @@ -1,1 +1,2 @@
  >  a
  > +b
  > EOF

empty series

  $ hg qseries

qimport valid patch followed by invalid patch

  $ hg qimport b.patch fakepatch
  adding b.patch to series file
  abort: unable to read file fakepatch
  [255]

valid patches before fail added to series

  $ hg qseries
  b.patch

  $ hg pull -q -r 0 . # update phase
  $ hg qimport -r 0
  abort: revision 0 is not mutable
  (see 'hg help phases' for details)
