07b2afef10 add Binds, WhiteBinds to CConnman::Options
Part of a series of changes to clean up the instantiation of connman
by decoupling the command line arguments.

We also now abort with an error when explicit binds are set with
-listen=0.

7f31762cb6 net: add an internal subnet for representing unresolved hostnames
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).

a7e3c2814c rpc: Add listen address to incoming connections in getpeerinfo
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.

6b3bb3d9ba Change LogAcceptCategory to use uint32_t rather than sets of strings.
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.

25da1ee36c build: cleanup: define MSG_DONTWAIT/MSG_NO_SIGNAL locally
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.

These are (afaik) all long-standing races or concurrent accesses. Going
forward, we can clean these up so that they're not all individual atomic
accesses.

- Reintroduce cs_vRecv to guard receive-specific vars
- Lock vRecv/vSend for CNodeStats
- Make some vars atomic.
- Only set the connection time in CNode's constructor so that it doesn't change
