Titouan Christophe d578727aae utils/checkpackagelib: add new check MissingCVEPatch
To indicate that a patch fixes a vulnerability in Buildroot, the convention is:
1. In the patch file, add a tag 'CVE: <cve id>'
2. In <pkg>.mk, and an entry to <PKG>_IGNORE_CVES, and add a comment above
   that new entry to reference the patch file(s)

However, as packages get bumped and their patches are added, removed or
rebased; it happens that IGNORE_CVES get outdated. One important issue is
marking a CVE as ignored, while the corresponding patch is not in Buildroot.

To detect such cases, add a new checker to checkpackagelib that finds
occurences of:

    # 000x-some-patch.patch
    PKG_IGNORE_CVES += CVE-XXXX-YYYY

For each one of them, ensure that the mentioned patch files actually exist
and contain the `CVE: ...` tag.

This directory contains various useful scripts and tools for working
with Buildroot. You need not add this directory in your PATH to use
any of those tools, but you may do so if you want.

brmake
    a script that can be run instead of make, that prepends the date in
    front of each line, redirects all of the build output to a file
    ("'br.log' in the current directory), and just outputs the Buildroot
    messages (those lines starting with >>>) on stdout.
    Do not run this script for interactive configuration (e.g. menuconfig)
    or on an unconfigured directory. The output is redirected so you will see
    nothing.

check-package
    a script that checks the coding style across the buildroot tree. It
    checks package's Config.in and .mk files, runs shellcheck for all shell
    scripts, flake8 for python files, checks for typos, etc.
    It checks the .checkpackageignore file if errors should be ignored and
    errors if there's a file listed that doesn't produce an error.

docker-run
    a script that runs a command (like make check-package) inside the
    buildroot CI docker container; pass no command to get an interactive
    shell.

genrandconfig
    a script that generates a random configuration, used by the autobuilders
    (http://autobuild.buildroot.org). It selects a random toolchain from
    support/config-fragments/autobuild and randomly selects packages to build.

get-developers
    a script to return the list of people interested in a specific part
    of Buildroot, so they can be Cc:ed on a mail. Accepts a patch as
    input, a package name or and architecture name.

scancpan
    a script to create a Buildroot package by scanning a CPAN module
    description.

scanpypi
    a script to create a Buildroot package by scanning a PyPI package
    description.

size-stats-compare
    a script to compare the rootfs size between two different Buildroot
    configurations. This can be used to identify the size impact of
    a specific option, of a set of specific options, or of an update
    to a newer Buildroot version...

test-pkg
    a script that tests a specific package against a set of various
    toolchains, with the goal to detect toolchain-related dependencies
    (wchar, threads...)
