131344715a Minor environment variable improvements 
- COIN and NET strip surrounding whitespace
- new environment variable RPC_HOST, similar to HOST, but
  for RPC.  Permits fine-grained control of which addresses
  the RPC server listens on.
- HOST and RPC_HOST strip surrounding whitespace from hostnames
  and IP addresses
- tests and documentation updated to match

69c1535d13 Use our listening Host/IP for outgoing connections also (#226) 
Explicitely set the local IP for outgoing connections, if we're listening
on only one Hostname or IP (of a multi-IP machine). This makes sure our
peers see our outgoing connections coming from the same IP that we're
listening on when we have a specific HOST= configured.

For machines with more than one IP this avoids source-destination
mismatch errors when advertizing our peer. Resolves kyuupichan/electrumx#225

a94d320e5d New feature: force peer discovery via proxy 
Set FORCE_PROXY to non-empty to force peer discovery to go
through the proxy.  See docs/ENVIRONMENT.rst

Wait for an attempt at proxy discovery to be made before beginning
peer discovery.

77a441ad06 Improve proxy handling 
Have a background proxy detection loop; removes need to check
specific peers at startup.
Consider proxy down once attempts to use it fail 3 times in a row.
Regularly attempt to rediscover a proxy if it is down.

d36d222489 Maintain more than one self-identity 
Rather than just retaining our clearnet identity from the environment,
maintain any tor one as well.  This is a little cleaner and avoids
confusion over port assignment when converting to real names.
