Optimize relaying of validation and proposal messages:

Browse Source 
With few exceptions, servers will typically receive multiple copies
of any given message from its directly connected peers. For servers
with several peers this can impact the processing latency and force
it to do redundant work. Proposal and validation messages are often
relayed with extremely high redundancy.

This commit, if merged, introduces experimental code that attempts
to optimize the relaying of proposals and validations by allowing
servers to instruct their peers to "squelch" delivery of selected
proposals and validations. Servers making squelching decisions by
a process that evaluates the fitness and performance of a given
server and randomly selecting a subset of the best candidates.

The experimental code is presently disabled and must be explicitly
enabled by server operators that wish to test it.
