0bc4f0447b style: rustfmt everything
This is why I was so intent on clearing the PR queue. This will
effectively invalidate all existing patches, so I wanted to start from a
clean slate.

We do make one little tweak: we put the default type definitions in
their own file and tell rustfmt to keep its grubby mits off of it. We
also sort it lexicographically and hopefully will enforce that from here
on.

ripgrep: max-column-preview --> max-columns-preview
Credit to @okdana for catching this. This naming is a bit more
consistent with the existing --max-columns flag.

ece1f50cfe printer: support previews for long lines
This commit adds support for showing a preview of long lines. While the
default still remains as completely suppressing the entire line, this
new functionality will show the first N graphemes of a matching line,
including the number of matches that are suppressed.

This was unfortunately a fairly invasive change to the printer that
required a bit of refactoring. On the bright side, the single line
and multi-line coloring are now more unified than they were before.

Closes #1078

a7d26c8f14 binary: rejigger ripgrep's handling of binary files
This commit attempts to surface binary filtering in a slightly more
user friendly way. Namely, before, ripgrep would silently stop
searching a file if it detected a NUL byte, even if it had previously
printed a match. This can lead to the user quite reasonably assuming
that there are no more matches, since a partial search is fairly
unintuitive. (ripgrep has this behavior by default because it really
wants to NOT search binary files at all, just like it doesn't search
gitignored or hidden files.)

With this commit, if a match has already been printed and ripgrep detects
a NUL byte, then it will print a warning message indicating that the search
stopped prematurely.

Moreover, this commit adds a new flag, --binary, which causes ripgrep to
stop filtering binary files, but in a way that still avoids dumping
binary data into terminals. That is, the --binary flag makes ripgrep
behave more like grep's default behavior.

For files explicitly specified in a search, e.g., `rg foo some-file`,
then no binary filtering is applied (just like no gitignore and no
hidden file filtering is applied). Instead, ripgrep behaves as if you
gave the --binary flag for all explicitly given files.

This was a fairly invasive change, and potentially increases the UX
complexity of ripgrep around binary files. (Before, there were two
binary modes, where as now there are three.) However, ripgrep is now a
bit louder with warning messages when binary file detection might
otherwise be hiding potential matches, so hopefully this is a net
improvement.

Finally, the `-uuu` convenience now maps to `--no-ignore --hidden
--binary`, since this is closer to the actualy intent of the
`--unrestricted` flag, i.e., to reduce ripgrep's smart filtering. As a
consequence, `rg -uuu foo` should now search roughly the same number of
bytes as `grep -r foo`, and `rg -uuua foo` should search roughly the
same number of bytes as `grep -ra foo`. (The "roughly" weasel word is
used because grep's and ripgrep's binary file detection might differ
somewhat---perhaps based on buffer sizes---which can impact exactly what
is and isn't searched.)

See the numerous tests in tests/binary.rs for intended behavior.

Fixes #306, Fixes #855

d9ca529356 libripgrep: initial commit introducing libripgrep
libripgrep is not any one library, but rather, a collection of libraries
that roughly separate the following key distinct phases in a grep
implementation:

  1. Pattern matching (e.g., by a regex engine).
  2. Searching a file using a pattern matcher.
  3. Printing results.

Ultimately, both (1) and (3) are defined by de-coupled interfaces, of
which there may be multiple implementations. Namely, (1) is satisfied by
the `Matcher` trait in the `grep-matcher` crate and (3) is satisfied by
the `Sink` trait in the `grep2` crate. The searcher (2) ties everything
together and finds results using a matcher and reports those results
using a `Sink` implementation.

Closes #162
