James Tucker 0957258f84 appc,ipn: prevent undesirable route advertisements
Individual route advertisements that are covered by existing routes are
no longer advertised. If an upstream returns 0.0.0.0, 127.x, and other
common unwanted addresses those are also rejected.

Updates #16425

James Tucker 245ddb157b appc: fix DomainRoutes copy
The non-referential copy destination doesn't extend the map contents,
but also the read of a non-key is returning a zero value not bound to
the map contents in any way.

James Tucker f27b2cf569 appc,cmd/sniproxy,ipn/ipnlocal: split sniproxy configuration code out of appc
The design changed during integration and testing, resulting in the
earlier implementation growing in the appc package to be intended now
only for the sniproxy implementation. That code is moved to it's final
location, and the current App Connector code is now renamed.

James Tucker b48b7d82d0 appc,ipn/ipnlocal,net/dns/resolver: add App Connector wiring when enabled in prefs
An EmbeddedAppConnector is added that when configured observes DNS
responses from the PeerAPI. If a response is found matching a configured
domain, routes are advertised when necessary.

The wiring from a configuration in the netmap capmap is not yet done, so
while the connector can be enabled, no domains can yet be added.
