[Buildroot] [PATCH 0/7] Add PURL support

[Thomas Perale]

This patch series add support for the PURL.

https://github.com/package-url/purl-spec

PURL are a software identifier similar to CPE.
More information on PURL can be found in the first patch of the series.

After testing the usage of PURL with DependencyTrack and
https://ossindex.sonatype.org I can see that it improves the tracking
of CVEs and version bump. Since it's easy to automate the PURL
generation in buildroot I wrote this patch that I use to add PURL to
CycloneDX SBOM.

The series includes support for PURL for these 'ecosystems':
  - pypi
  - cargo
  - cpan
  - golang

The tracking of CPAN packages is not supported by OSSIndex but these
changes were proposed by François Perrad in the following series:
