Remove mutexes from Comms

It was never fully thread-safe.
e.g. calling SendProtoBuf concurrently from 2 threads

Also not all users need the thread-safety thus it's better left off to be done externally by the ones that require it.

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.
