Collect existing fix commits and patches open datasets

[pombredanne]

We are adding support for formal fix commits tracking in:

• Improve tracking of fix commits #1695

We should then collect existing fix commit datasets. Here is a running list:

• Android fixes from https://github.com/quarkslab/aosp_dataset
• @copernico project-kb https://github.com/SAP/project-kb/tree/vulnerability-data
  And the tool https://github.com/SAP/project-kb/tree/main/prospector designed to work with https://github.com/eclipse/steady . We already have an importer in https://github.com/aboutcode-org/vulnerablecode/blob/main/vulnerabilities/importers/kaybee.py for this data, but this needs to be updated for fix commits
  • and also: https://github.com/SAP/project-kb/tree/main/MSR2019
• OSV data
• Import data from https://github.com/nluedtke/linux_kernel_cves #564 for https://github.com/pombredanne/linux_kernel_cves now archived
• GNU Libc fix commits Add glibc advisories #1362
• Add support in Apache Tomcat to collect commits #2129
• Collect fix commits from https://github.com/google/vulncode-db/  #118
