d52eff2843 sys/targets: Disable PIE/ASLR when building tests 
Due to issues with ASLR + ASan on ppc64le (see #1446), add the -no-pie
flag to the test target so tests will pass.

c4b9981b5f Disable checkFeature[FeatureNetworkInjection] for NetBSD 
There is a problem with the image. Until the problem will be resolved,
disable the feature as it causes premature death of the syzbot setup.

0f33548a39 tools/syz-trace2syz: disable golangci-lint 
A new version of golangci-lint started failing trying to build syz-trace2syz
(because we already ignore some files).
Ignore the rest of files to fix the failure.

b2f369e56e executor, host, csource: Add support to enable KCSAN 
By default, the current KCSAN .config does not enable KCSAN during boot,
since we encounter races during boot which would prevent syzkaller from
ever executing.

This adds support to detect if KCSAN is available, and enables it on the
fuzzer host.

c7a4fb9986 sys/linux/dev_binder.txt: also support real-world binder device names 
It was reported that binder isn't covered when using syzkaller on a real
Android device, since the binder device names are different.  Update the
descriptions to know about the real-world device names too.

eb6b9855e0 pkg/report: improve uvm_fault reports on OpenBSD 
Some reports[1] does not include a symbol but rather an address in the
"Stopped at" line. There's unfortunately no useful context to add to the
title so make them generic instead.

* Modify pollCompletedJobs(); for bugs that are already marked as fixed,
invalid or duplicate do not report bisection results.
* Add TestNotReportingAlreadyFixed() to test that reporting does not
occur for already fixed bugs.

aac00cc3db pkg/vcs: handle git commits without a body 
OpenBSD uses cvs and does not enforce the standard Git convention for
commit messages of putting a summary followed by a new line and body.
If such commit[1] contains a `Reported-by` header, it's currently not
detected. Instead, if the body is empty try to extract data from the
commit summary.

2b854f96b1 tools: add syz-expand 
The syz-expand tools allows to parse a program and print it including all
the default values. This is mainly useful for debugging, like doing manual
program modifications while trying to come up with a reproducer for some
particular kernel behavior.
