ripgrep: update to 0.10.0

ripgrep 0.10.0:

This is a new minor version release of ripgrep that contains some major new
features, a huge number of bug fixes, and is the first release based on
libripgrep. The entirety of ripgrep's core search and printing code has been
rewritten and generalized so that anyone can make use of it.

Major new features include PCRE2 support, multi-line search and a JSON output
format.

BREAKING CHANGES:

    The minimum version required to compile Rust has now changed to track the
    latest stable version of Rust. Patch releases will continue to compile with
    the same version of Rust as the previous patch release, but new minor
    versions will use the current stable version of the Rust compile as its
    minimum supported version.
    The match semantics of -w/--word-regexp have changed slightly. They used
    to be \b(?:<your pattern>)\b, but now it's
    (?:^|\W)(?:<your pattern>)(?:$|\W). This matches the behavior of GNU grep
    and is believed to be closer to the intended semantics of the flag. See
    #389 for more details.

Feature enhancements:

    FEATURE #162:
    libripgrep is now a thing. The primary crate is
    grep.
    FEATURE #176:
    Add -U/--multiline flag that permits matching over multiple lines.
    FEATURE #188:
    Add -P/--pcre2 flag that gives support for look-around and backreferences.

    FEATURE #321:
    Add --one-file-system flag to skip directories on different file systems.
    FEATURE #404:
    Add --sort and --sortr flag for more sorting. Deprecate --sort-files.

    FEATURE #997:
    The --passthru flag now works with the --replace flag.
    FEATURE #1038-1:

    Add compile time and runtime CPU features to --version output.
    BUG #1028:
    Don't complete bare pattern after -f in zsh.

ripgrep 0.9.0:

BREAKING CHANGES:

    When --count and --only-matching are provided simultaneously, the
    behavior of ripgrep is as if the --count-matches flag was given. That is,
    the total number of matches is reported, where there may be multiple matches
    per line. Previously, the behavior of ripgrep was to report the total number
    of matching lines. (Note that this behavior diverges from the behavior of
    GNU grep.)
    Octal syntax is no longer supported. ripgrep previously accepted expressions
    like \1 as syntax for matching U+0001, but ripgrep will now report an
    error instead.
    The --line-number-width flag has been removed. Its functionality was not
    carefully considered with all ripgrep output formats.
    See #795 for more
    details.

Feature enhancements:

    Added or improved file type filtering for Android, Bazel, Fuschia, Haskell,
    Java and Puppet.
    FEATURE #411:
    Add a --stats flag, which emits aggregate statistics after search results.
    FEATURE #646:

    .ignore and .gitignore files.
    FEATURE #702:
    Support \u{..} Unicode escape sequences.
    FEATURE #812:
    Add -b/--byte-offset flag that shows the byte offset of each matching line.
    FEATURE #814:
    Add --count-matches flag, which is like --count, but for each match.
    FEATURE #880:
    Add a --no-column flag, which disables column numbers in the output.
    FEATURE #898:
    Add support for lz4 when using the -z/--search-zip flag.
    FEATURE #924:
    termcolor has moved to its own repository:
    https://github.com/BurntSushi/termcolor
    FEATURE #934:
    Add a new flag, --no-ignore-global, that permits disabling global
    gitignores.
    FEATURE #967:
    Rename --maxdepth to --max-depth for consistency. Keep --maxdepth for
    backwards compatibility.
