Extend the libbpf documentation with a table of program types, attach points and ELF section names. The table uses data from program_types.csv which is generated from tools/lib/bpf/libbpf.c during the documentation build. Patch 1 adds subdir support to Documentation/Makefile and changes userspace-api/media to use this instead of being a special case. Patch 2 adds the the program_types documentation with a new makefile in the libbpf doc directory to generate program_types.csv I plan to look at adding info about format of section "extras" as a follow-on. v1 -> v2: Automate the generation of program_types.csv as suggested by Andrii Nakryiko.
