Merge branch 'bpf-bpftool-libbpf-improvements' 



Jakub Kicinski says:

====================
Set of random updates to bpftool and libbpf.  I'm preparing for
extending bpftool prog load, but there is a good number of
improvements that can be made before bpf -> bpf-next merge
helping to keep the later patch set to a manageable size as well.

First patch is a bpftool build speed improvement.  Next missing
program types are added to libbpf program type detection by section
name.  The ability to load programs from '.text' section is restored
when ELF file doesn't contain any pseudo calls.

In bpftool I remove my Author comments as unnecessary sign of vanity.
Last but not least missing option is added to bash completions and
processing of options in bash completions is improved.
