The main changes are:

1) Fix out of bounds backwards jumps due to a bug in dead code
   removal, from Daniel.

2) Fix libbpf users by detecting unsupported BTF kernel features
   and sanitize them before load, from Andrii.

3) Fix undefined behavior in narrow load handling of context
   fields, from Krzesimir.

4) Various BPF uapi header doc/man page fixes, from Quentin.

5) Misc .gitignore fixups to exclude built files, from Kelsey.
