This introduces a new way of linking Serval executables and dynamic libraries from static libraries like libservald.a -- called "feature-driven" linking. The Makefile now links servald and serval-tests from libservald.a, rather than from an explicit list of object (.o) files. Thanks to the section-based method for registering functions such as HTTP handlers, CLI commands and MDP handlers, these object files had become "stand-alone" and hence were no longer included in the link because there was no unresolved reference that required them to be linked in. The new "feature.h" provides the DECLARE_FEATURE(name) macro that each stand-alone source file uses to declare the named feature(s) it provides. Each executable can call the USE_FEATURE(name) macro in any of its explicitly-linked source files to cause the corresponding object(s) to be included in the link, eg, servald_features.c. The DEFINE_BINDING() macro has been extended so that every individual MDP binding is given a feature name based on its port number macro, eg, "mdp_binding_MDP_PORT_ECHO". Some features have been factored into their own separate source files so they can be omitted or included in a build independently of each other: - the MDP bindings for MDP_PORT_DNALOOKUP, MDP_PORT_ECHO, MDP_PORT_TRACE, MDP_PORT_KEYMAPREQUEST, MDP_PORT_RHIZOME_xxx, MDP_PORT_PROBE, MDP_PORT_STUN, MDP_PORT_STUNREQ - the CLI "log" and "echo" commands - the CLI "rhizome direct" command The JNI source files are only compiled if the <jni.h> header is present, otherwise they are omitted from libservald.so.
