4289b64aa7 Disallow clone3, unsafe clone and unshare flags
Ability to create new namespaces and getting capabilities in there exposes a big kernel attack surface.

b350a41a10 Gather more coverage data
Switch to ForkWithFlags for InitProcess (it will not reset coverage).
Explicitly dump coverage after initial namespace setup.
Return instead of exiting from libunwind sandbox.

3ea315858d Remove mutexes from Comms
It was never fully thread-safe.
e.g. calling SendProtoBuf concurrently from 2 threads
could result in a data race.
Also not all users need the thread-safety thus it's better left off to be done externally by the ones that require it.

e23acfd7e7 Made slight optimizations in Sandbox2's comms.
The optimizations are:
* Reduced the number of calls to `write` (originating from `SendTLV()`) from 3 to 1-2 (depending on size of the payload).
* Reduced the number of calls to `read()` (originating from `RecvTLV()`) from 3 to 2.
