0a7cf4ec63 manager: Fix default value for 'sandbox' (#666) 
docs: fix default sandbox value

The docs and code comments state in several places that 'setuid'
is the default sandbox value.  However, the default is actually
'none'.  Fix docs.

419000cc0a vm: fix "kill fuzzer on first kernel bug" 
The problem with that commit is that for GCE implementation
we immidiately kill console connection too when receive diagnose signal.
This leads to truncated output.

788351b1b0 pkg/csource: rewrite gen.sh in Go 
Shell files cause portability problems.
On Linux it's hard to install /bin/sh,
/bin/bash is not present on *BSD.
Any solution is hard to test on Darwin.
Don't even want to mention Windows.

Just do it in Go.

9d92841b4e pkg/csource: tidy generated code 
1. Remove unnecessary includes.
2. Remove thunk function in threaded mode.
3. Inline syscalls into main for the simplest case.
4. Define main in common.h rather than form with printfs.
5. Fix generation for repeat mode
   (we had 2 infinite loops: in main and in loop).
6. Remove unused functions (setup/reset_loop, setup/reset_test,
   sandbox_namespace, etc).

c3da5dc5e0 executor: simplify event_timedwait

so use it instead of manual clock_gettime calls
which tend to be bulkier.

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.
