03f7605322 Rename --files-without-matches to --files-without-match.
This is to be consistent with grep.

bd3e7eedb1 Add --files-without-matches flag.
Performs the opposite of --files-with-matches: only shows paths of
files that contain zero matches.

Closes #138

0302d58eb8 Fix stdin bug with --file.
When `rg -f-` is used, the default search path should be `./` and not
`-`.

92dc402f7f Switch from Docopt to Clap.
There were two important reasons for the switch:

1. Performance. Docopt does poorly when the argv becomes large, which is
   a reasonable common use case for search tools. (e.g., use with xargs)
2. Better failure modes. Clap knows a lot more about how a particular
   argv might be invalid, and can therefore provide much clearer error
   messages.

While both were important, (1) made it urgent.

Note that since Clap requires at least Rust 1.11, this will in turn
increase the minimum Rust version supported by ripgrep from Rust 1.9 to
Rust 1.11. It is therefore a breaking change, so the soonest release of
ripgrep with Clap will have to be 0.3.

There is also at least one subtle breaking change in real usage.
Previous to this commit, this used to work:

    rg -e -foo

Where this would cause ripgrep to search for the string `-foo`. Clap
currently has problems supporting this use case
(see: https://github.com/kbknapp/clap-rs/issues/742),
but it can be worked around by using this instead:

    rg -e [-]foo

or even

    rg [-]foo

and this still works:

    rg -- -foo

This commit also adds Bash, Fish and PowerShell completion files to the
release, fixes a bug that prevented ripgrep from working on file
paths containing invalid UTF-8 and shows short descriptions in the
output of `-h` but longer descriptions in the output of `--help`.

e9cd0a1cc3 Allow specifying patterns with -f FILE and -f-
This is a somewhat basic implementation of `-f-` (#7), with unit tests.
Changes include:

1. The internals of the `pattern` function have been refactored to avoid
   code duplication, but there's a lot more we could do.  Right now we
   read the entire pattern list into a `Vec`.
2. There's now a `WorkDir::pipe` command that allows sending standard
   input to `rg` when testing.

Not implemented: aho-corasick.

5b73dcc8ab Rework parallelism in directory iterator.
Previously, ignore::WalkParallel would invoke the callback for all
*explicitly* given file paths in a single thread, which effectively
meant that `rg pattern foo bar baz ...` didn't actually search foo, bar
and baz in parallel.

The code was structured that way to avoid spinning up workers if no
directory paths were given. The original intention was probably to have
a separate pool of threads responsible for searching, but ripgrep ended
up just reusing the ignore::WalkParallel workers themselves for searching,
and thereby subjected to its sub-par performance in this case.

The code has been restructured so that file paths are sent to the workers,
which brings back parallelism.

b272be25fa Add parallel recursive directory iterator.
This adds a new walk type in the `ignore` crate, `WalkParallel`, which
provides a way for recursively iterating over a set of paths in parallel
while respecting various ignore rules.

The API is a bit strange, as a closure producing a closure isn't
something one often sees, but it does seem to work well.

This also allowed us to simplify much of the worker logic in ripgrep
proper, where MultiWorker is now gone.

d79add341b Move all gitignore matching to separate crate.
This PR introduces a new sub-crate, `ignore`, which primarily provides a
fast recursive directory iterator that respects ignore files like
gitignore and other configurable filtering rules based on globs or even
file types.

This results in a substantial source of complexity moved out of ripgrep's
core and into a reusable component that others can now (hopefully)
benefit from.

While much of the ignore code carried over from ripgrep's core, a
substantial portion of it was rewritten with the following goals in
mind:

1. Reuse matchers built from gitignore files across directory iteration.
2. Design the matcher data structure to be amenable for parallelizing
   directory iteration. (Indeed, writing the parallel iterator is the
   next step.)

46dff8f4be Be better with short circuiting with --quiet.
It didn't make sense for --quiet to be part of the printer, because --quiet
doesn't just mean "don't print," it also means, "stop after the first
match is found." This needs to be wired all the way up through directory
traversal, and it also needs to cause all of the search workers to quit
as well. We do it with an atomic that is only checked with --quiet is
given.

2b943eda47 Make file type filtering a lot faster.
We do this by avoiding using a RegexSet (*sigh*). In particular, file
type matching has much simpler semantics than gitignore files, so we don't
actually need to care which file type matched. Therefore, we can get away
with a single regex with a giant alternation.

ca058d7584 Add support for memory maps.
I though plain `read` had usurped them, but when searching a very small
number of files, mmaps can be around 20% faster on Linux. It'd be really
unfortunate to leave that on the table.

Mmap searching doesn't support contexts yet, but we probably don't really
care. And duplicating that logic doesn't sound fun. Without contexts, mmap
searching is delightfully simple.
