.SystemTap rebased to version 4.3
The SystemTap instrumentation tool has been updated to version 4.3, which provides multiple bug fixes and enhancements. Notable changes include:
* Userspace probes can be targeted by hexadecimal `buildid` from `readelf -n`. This alternative to a path name enables matching binaries to be probed under any name, and thus allows a single script to target a range of different versions. This feature works well in conjunction with the elfutils `debuginfod` server.
* Script functions can use probe `$context` variables to access variables in the probed location, which allows the SystemTap scripts to use common logic to work with a variety of probes.
* The `stapbpf` program improvements, including try-catch statements, and error probes, have been made to enable proper error tolerance in scripts running on the BPF backend.
