9adfa8760f pkg/report: improve witness extraction for OpenBSD 
Reports from witness regarding returning to userspace with locks held is not
unique enough, causing all lock leaks to be grouped under the same bug.
Instead try to extract the name of syscall where the first held lock was
grabbed.

While here, shorten the title a bit.

pkg/report: revert bucketing MAX_STACK_TRACE_ENTRIES reports (#1357) 
MAX_STACK_TRACE_ENTRIES crash reports caused by a particular issues can come
from any part of the kernel, so bucketing them based on the stack trace is
pointless and only creates duplicate bug reports.

4d4a4420e7 pkg/report: add Type/Frame to Report 
In several places we do special handling for some crash types.
Currently we compare report title with magic strings,
which is error-prone. Add explicit Type to reports.

4e7ecf0713 pkg/report: preserve trackback from other CPUs 
For some bug types kernel produces traceback of all CPUs
(which is presumably useful for these crashes).
However, we currently throw it away because it has context
different from the oops context.
Detect such traceback and preserve output.
