Ricardo Martincoski ddf4586b00 utils/check-package: decouple adding rules from fixing all intree files
When a new check_function is added to check-package, often there are
files in the tree that would generate warnings.

An example is the Sob check_function for patch files:
| $ ./utils/check-package --i Sob $(git ls-files) >/dev/null
| 369301 lines processed
| 46 warnings generated
Currently these warnings are listed when calling check-package directly,
and also at the output of pkg-stats, but the check_function does not run
on 'make check-package' (that is used to catch regressions on GitLab CI
'check-package' job) until all warnings in the tree are fixed.
This (theoretically) allows new .patch files be added without SoB,
without the GitLab CI catching it.

So add a way to check-package itself ignore current warnings, while
still catching new files that do not follow that new check_function.

Add a file named .checkpackageignore to the buildroot topdir.
It contains the list of check_functions that are expected to fail for
each given intree file tested by check-package.
Each entries is in the format:
<filename> <check_function> [<check_function> ...]

These are 2 examples of possible entries:
package/initscripts/init.d/rcK ConsecutiveEmptyLines EmptyLastLine Shellcheck
utils/test-pkg Shellcheck

Keeping such a list allows us to have fine-grained control over which
warning to ignore.

In order to avoid this list to grow indefinitely, containing entries for
files that are already fixed, make each entry an 'expected to fail'
instead of just an 'ignore', and generate a warning if a check_function
that was expect to fail for a given files does not generate that
warning.
Unfortunately one case that do not generate warning is an entry for a
file that is deleted in a later commit.

By default, all checks are applied. The --ignore-list option allows to
specify a file that contains the list of warnings that should be
ignored.

The paths in the ignore file must be relative to the location of the
ignore file itself, which means:

 - in the main Buildroot tree, the paths in the ignore file are
   relative to the root of the main Buildroot tree

 - in a BR2_EXTERNAL tree, if the ignore file is at the root of the
   BR2_EXTERNAL, the paths it contains must be relative to that root
   of the BR2_EXTERNAL

This is one more step towards standardizing the use of just 'make
check-package' before submitting patches to the list.

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 of a package's Config.in and
    .mk files, and also tests them for various types of typoes.

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...)
