Try extracting report from console output only first. If that doesn't work,
try extracting it from the whole log.
Add regexp for executor printed BUGs.
Optimize regexps for rcu detected stalls.
Update rep.StartPos and rep.EndPos in vm/vm.go as well as rep.Output.
Currently getting a complete report requires a complex,
multi-step dance (including getting information that
external users are not interested in -- guilty file).
Simplify interface down to 2 functions: Parse and Symbolize.
Parse does what it did before, Symbolize symbolizes report
and fills in maintainers. This simplifies both implementations
of Reporter interface and all users of the interface.
Potentially we could get this down to 1 function Parse
that does everything. However, (1) Symbolize can fail,
while Parse cannot, (2) usually we want to ignore (log)
Symbolize errors, but otherwise proceed with the report,
(3) repro does not need symbolization for all but the
last report.
Whole raw output is indivisble part of Report,
currently we always pass Output separately along with Report.
Make Output a Report field.
Then, put whole Report into manager Crash and repro context and Result.
There is little point in passing Report as aa bunch of separate fields.
We currently have several names for crash attributes, which is disturbing.
E.g. crash title is called "Title" or "Desc". Name them consistently.
Title - single line bug identity.
Report - whole crash text.
Log - whole fuzzer/kernel output.
