cmd/swarm, swarm/api: bzzr improve + networkid prio
fixes #3444 fixes #3494 networkid override Added comments to explain why test against 0 appears twice * Command line overrides saved config, saved config overrides system default --- fixes #3476 bzzr get with path Finally a hopefully clean commit for this PR Added check for empty path to avoid SIGSEGV in path parser and resolver Added requested tests for empty path and non-existing manifest. However signature for StartHTTPServer had changed. Now it's hacked as so: StartHttpServer(api.API, &Server{Addr: "127.0.0.1:8504", CorsString: ""}) * Parse url before resolve when path and ENS is supplied, example * swarm/api/http proxy server test for retrieval of subpath through get * Removed nil entry assignment on subtrie leaf in recursive key retrieval * Cleaned up path-or-no-path condition in proxy server get handler * swarm: processed with gofmt refers to lash/go-ethereum@90daa7a * swarm: Added public access method Parse alias to parse * swarm: processed with gofmt References nolash/go-ethereum@2ec3fd7 * Rename parse to Parse, removed alias
