depot_autopilot: rework log matching
* The log history of a test is stored as a whole for the lifetime of the test. * Matching of the log history against log patterns is done correctly now (previously, a pattern like "AAB" on an input like "AAAB" wouldn't have triggered). * Use memcmp, memcpy, memmove instead of the former character-wise operations. * Sanitizing of log input and log patterns now works more generic through the new Filter class for all replacements/removals. * Sanitizing is done as soon as a string is available and remains for the lifetime of the test. * Sanitizing doesn't interfer with the matching algorithm. * Decomposing into small clearly named functions. Ref #3555
