ABI tracker for libssh

[Ponomarenko Andrey <andrewponomarenko@xxxxxxxxx>]

Hello,

The libssh library is now included to the ABI tracker: http://abi-laboratory.pro/tracker/timeline/libssh/

The tracker checks for new releases of the library every other day and verifies backward binary compatibility. The current version from git is also analyzed, so one can look at the future changes in the API/ABI. Hope it will be helpful for maintainers and users of the library.

Thank you.
