ABI changes analysis report for libdrm

[Ponomarenko Andrey]

Hello,

I'm working on a new project for backward compatibility analysis of the Linux ABIs. The report for libdrm 2.4.25-2.4.68 has been recently added to the project and updated every other day: http://abi-laboratory.pro/tracker/timeline/libdrm/

The report is generated with the help of the abi-compliance-checker, abi-dumper and abi-tracker tools: https://github.com/lvc/abi-tracker

Hope this will help users, maintainers and developers of the library to maintain backward compatibility.

Thank you.
