4dcfea28eb pkg/host: support test OS 
test OS parasitizeson other OSes just as akaros,
and there is nothing to detect as well.
So use the same stub for test as for akaros.

0889ba7a79 adb: Add console logic for ttyUSB.serial 
By using UDEV rules, we can create device nodes which exist at

	/dev/ttyUSB.{android device serial}

Which makes it easier to determine which console belongs to a device.

While this is non-standard behavior, it's an inexpensive path check
and makes the lookup faster and deterministic.

9182049979 pkg/csource: remove /bin/bash assumption

script runs fine with regular /bin/sh.

375a3e31e1 pkg/build: save kernel config early 
Currently we don't capture kernel config for broken builds
because the config is saved as the last step.
Save it as early as possible.

beb957b793 vm/qemu, vm/gce: kill fuzzer on first kernel bug 
Some kernel bugs don't stop kernel.
For such bugs whiel vm.MonitorExecution waits for kernel output for 10 secs,
fuzzer continues running programs and produces tons of output
after the kernel bug message. Kill fuzzer once MonitorExecution
detects a kernel bug.

9fe4bdc5f1 executor: overhaul 
Make as much code as possible shared between all OSes.
In particular main is now common across all OSes.
Make more code shared between executor and csource
(in particular, loop function and threaded execution logic).
Also make loop and threaded logic shared across all OSes.
Make more posix/unix code shared across OSes
(e.g. signal handling, pthread creation, etc).
Plus other changes along similar lines.
Also support test OS in executor (based on portable posix)
and add 4 arches that cover all execution modes
(fork server/no fork server, shmem/no shmem).

This change paves way for testing of executor code
and allows to preserve consistency across OSes and executor/csource.

06c33b3af0 prog: sanitize calls after hints mutation 
Hints mutation could produce unsanitized calls.
Sanitize calls after hints mutation.
Also sanitize on load (in validate), because bad programs
can already be in corpuses. And it's just the right thing
to do because sanitization rules can change over time.
