Rename the logging primitive functions and utility functions, prefixing all with 'serval_log', eg: logMessage() -> serval_logf() etc. Add an XPRINTF xhexdump() function and use it to implement the serval_log_hexdump() utility, renamed from dump(). Add macros WHY_dump(), WARN_dump(), HINT_dump() and DEBUG_dump(), and use them everywhere. Remove the 'log.console.dump_config' and 'log.file.dump_config' configuration options; configuration is now dumped in every log prolog. The logging system now constructs the log prolog by invoking the new 'log_prolog' trigger, so that it no longer depends on the version string and configuration system. Any system that wants to present a message in the log prolog can define its own trigger, which calls standard log primitives to print the message. Split the logging system into a front-end (log.c) that provides the logging primitives and is independent of the configuration system, and a set of back-end "outputters" (log_output_console.c, log_output_file.c, log_output_android.c) that may depend on the configuration system and are decoupled from the front-end using the 'logoutput' link section. These log outputters are explicitly linked into executables by the Makefile rules, but could also be linked in using USE_FEATURE(). The USE_FEATURE() calls have _not_ been added to servald_features.c, so that different daemon executables can be built with the same feature set but different log outputs.
