[bpf-next,0/5] veristat: further usability improvements

Message

A small patch set adding few usability improvements and features making
veristat a more convenient tool to be used for work on BPF verifier:

  - patch #2 speeds up and makes stats parsing from BPF verifier log more
    robust;

  - patch #3 makes veristat less strict about input object files; veristat
    will ignore non-BPF ELF files;

  - patch #4 adds progress log, by default, so that user doing
    mass-verification is aware that veristat is not stuck;

  - patch #5 allows to tune requested BPF verifier log level, which makes
    veristat a simplest way to get BPF verifier log, especially successfully
    verified ones.

Andrii Nakryiko (5):
  selftests/bpf: add sign-file to .gitignore
  selftests/bpf: make veristat's verifier log parsing faster and more
    robust
  selftests/bpf: make veristat skip non-BPF and failing-to-open BPF
    objects
  selftests/bpf: emit processing progress and add quiet mode to veristat
  selftests/bpf: allow to adjust BPF verifier log level in veristat
