[PATCH v5 0/3] Fuzzer pattern-matching, timeouts, and instrumentation-filtering

[Alexander Bulekov]

v5:
    - Fix a name collision in 3/3, between "GString *pattern" and the
      struct pattern type, which lead to some bad heap problems during
      fuzzing
v4:
    - Instead of changing the patterns in the AC97 and ES1370 configs,
      make the type/name pattern matching case-insensitive.
    - Copy the instrumentation filter into the build-dir, so it can be
      adapted on-the-fly.
v3:
    - Check in ./configure whether clang supports -fsanitize-coverage-allowlist
v2:
    - Add the instrumentation filter to the instrumentation filter patch

These patches
1.) Change generic-fuzzer timeouts so they are reconfigured prior to
each individual IO command, to allow for longer-running inputs
2.) Add an instrumentation filter to prevent libfuzzer from tracking
noisy/irrelevant parts of the code.
3.) Make pattern-matching against types/names case-insensitive.

Alexander Bulekov (3):
  fuzz: adjust timeout to allow for longer inputs
  fuzz: add an instrumentation filter
  fuzz: make object-name matching case-insensitive
