This represents yet another iteration on how `ignore` enqueues and
distributes work in parallel. The original implementation used a
multi-producer/multi-consumer thread safe queue from crossbeam. At some
point, I migrated to a simple `Arc<Mutex<Vec<_>>>` and treated it as a
stack so that we did depth first traversal. This helped with memory
usage in very wide directories.
But it turns out that a naive stack-behind-a-mutex can be quite a bit
slower than something that's a little smarter, such as a work-stealing
stack used in this commit. My hypothesis for why this helps is that
without the stealing component, work distribution can get stuck in
sub-optimal configurations that depend on which directory entries get
assigned to a particular worker. It's likely that this can result in
some workers getting "more" work than others, just by chance, and thus
remain idle. But the work-stealing approach heads that off.
This does re-introduce a dependency on parts of crossbeam which is kind
of a bummer, but it's carrying its weight for now.

When searching subdirectories the path was not correctly built and
included duplicate parts. This fix will remove the duplicate part if
possible.

This PR adds `*.bat` and `*.cmd` file types.
In doing so, it makes a distinction between batch files (old standard
from the MS-DOS era) and command scripts (new flavor - can operate on
batch files, although `*.cmd` is preferred for various reasons, the
main one being batch files will set `ERRORLEVEL` following inconsistent
MS-DOS style rules[1]).

We also make py/python, md/markdown and ts/typescript aliases of one
another.
Note that this only introduces aliases at the point where default types
are defined. This just makes them a bit easier to read/write, and also
makes it easier to expose more names that describe the same thing.

*.adb and *.ads are the usual extensions for Ada source code,
and *.gpr indicates a GPRbuild project file used for Ada, and
these days often being combined with alire for package dependency
resolution. Alire stores a bunch of files named alire.toml in
different directories in your (gitignored) cache/dependencies/...
Closes#2013
Eclasses are "ebuild libraries" and generally if you're filtering
for/filtering out an ebuild/eclass, you don't want the other either.

I have reservations about this, but it looks useful and doesn't seem
terribly onerous to support. The `ignore` crate will really always need
to have some kind of logic supporting this in some form I think.
Closes#2482
This removes most of the Unicode features as they aren't currently
used. We can always add them back later if necessary.
We can avoid the unicode-perl feature by changing `\s` to `[[:space:]]`,
which uses the ASCII-only definition of `\s`. Since we don't expect
non-ASCII whitespace in git config files, this seems okay.
Closes#2502
GraphQL file extensions: .graphql and .graphqls (schema)
We could also add `.gql`, but perhaps it's less correct to do so. We'll
start conservatively here, and we can always add `.gql` later.

This adds some lesser known extensions.
Notably, it adds php7 and php8, but not php6. Apparently,
php6 was never a thing: https://wiki.php.net/rfc/php6
PR #2263
When a glob pattern ended with a \/, and since we permit backslash
escapes, the glob parser gave a "dangling escape" error. Which is weird,
because the \ is clearly not dangling.
The issue is that the layer above the glob parser, the gitignore parser,
was stripping the trailing / so that it wouldn't be part of the matching
logic. Of course, stripping the trailing / while it is escaped without
removing the backslash escape is wrong. So we do that here.

Like .hpp, .hh is an occasionally used extension for C++ headers
(to distinguish them from C headers). At least one popular project,
FreeBSD, uses this extension.
