71cbe86566 Switch to feature-driven linking
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.

43e76ec7b5 Change signature of strn_fromprint()
The 'dst' parameter is now (char *) instead of (unsigned char *) because
in general it is used to produce human-readable (ASCII) strings, not
binary data.

90e02141d1 Reimplement WHY() macro without comma operator
GCC 4.9 and later warn about unused values produced by the comma
operator.  Since the -Wno-unused-value option was removed from the
non-Android Makefile.in, it will not compile the WHY() macro and its
variants, with the -Wall option.

This commit removes the comma operator from the WHY() macro and its
variants, and replaces it with a new inline wrapper function.

This commit also removes the WHYNULL() macro and fixes the three places
it was used.

d436705e64 Fix conflict on UNUSED() macro from OpenJDK 7
The OpenJDK 7 recently introduced the UNUSED() macro in their jni_md.h
header file, which is included from <jni.h>.  This causes a
compile-error if "constants.h", which defines our own UNUSED() macro, is
included as well as <jni.h>.

The OpenJDK UNUSED() macro is unsuitable for our own use, because it
prefixes the unused identifier with "UNUSED_" whereas we depend on the
parameter name remaining unchanged.

I have reported this as a Request for Enhancement with Oracle Java,
asking them to remove the UNUSED() macro, since it is not used by any
JNI or Java extension header files.  Review ID: JI-9013689.

In the meantime, constants.h now undefines UNUSED before defining it, so
including <jni.h> before "constants.h" will avoid a compile error.

bb677e50fd Refactor keyring open/seed out of server()
Now the keyring is opened and seeded before the server daemon process is
forked, and any keyring error prevents the server from starting

No longer necessary to pass a (cli_parsed*) argument to server()

53c1b1c04c Filesystem Heirarchy Standard (FHS) paths
If no instance directory specified, then use paths like
/etc/serval/serval.conf
/var/cache/serval
/var/log/serval
/var/run/serval
etc. for files, instead of all in a single directory.

Log all directory creation as INFO messages.

Interpretation of log.file.directory_path has changed slightly.

Updated servald configuration tech doc.
