This commit adds a method Init(const Options& connOptions) which is called by both the constructor and CConnman::Start(...). This method initializes nLocalServices and the other relevant values from the supplied Options object.

This addresss the TODO to avoid resolving twice.
2017-06-14net: add an internal subnet for representing unresolved hostnamesCory Fields
We currently do two resolves for dns seeds: one for the results, and one to serve in addrman as the source for those addresses. There's no requirement that the source hostname resolves to the stored identifier, only that the mapping is unique. So rather than incurring the second lookup, combine a private subnet with a hash of the hostname. The resulting v6 ip is guaranteed not to be publicy routable, and has only a negligible chance of colliding with a user's internal network (which would be of no consequence anyway).

2017-06-05rpc: Add listen address to incoming connections in `getpeerinfo`Wladimir J. van der Laan
This adds the listening address on which incoming connections were received to the CNode and CNodeStats structures. The address is reported in `getpeerinfo`. This can be useful for distinguishing connections received on different listening ports (e.g. when using a different listening port for Tor hidden service connections) or different networks.

2017-04-01Change LogAcceptCategory to use uint32_t rather than sets of strings.Gregory Maxwell
This changes the logging categories to boolean flags instead of strings. This simplifies the acceptance testing by avoiding accessing a scoped static thread local pointer to a thread local set of strings. It eliminates the only use of boost::thread_specific_ptr outside of lockorder debugging. This change allows log entries to be directed to multiple categories and makes it easy to change the logging flags at runtime (e.g. via an RPC, though that isn't done by this commit.) It also eliminates the fDebug global. Configuration of unknown logging categories now produces a warning.

2017-03-05build: cleanup: define MSG_DONTWAIT/MSG_NO_SIGNAL locallyWladimir J. van der Laan
Define MSG_DONTWAIT and MSG_NO_SIGNAL in the implementation files that use them (`net.cpp` and `netbase.cpp`), instead of compat.h which is included all over the place. This avoids putting them in the global namespace, as defining them as 0 is a hack that works for our specific usage, but it is not a general solution. Also makes sure they are defined only once so the `!defined(MSG_x)` guard can go.
