c35af0617a Fix header files for Xcode iOS build
- make "debug.h" a private header so that the DEBUG() macro does not
  interfere with Xcode Debug builds, which set DEBUG=1
- move all #include "debug.h" from headers into .c files
- move 'struct idebug' into a new public header "idebug.h" so that
  "log.h" can be public
- move HTTPD port number defs from "httpd.h" to "constants.h", so that
  "httpd.h" can be private and "conf.h" can be public
- add missing nested includes so each header compiles stand-alone
  without error
- #include "sodium.h" instead of <sodium.h>
- #include "sqlite3.h" instead of <sqlite3.h>
- add header guard to "fifo.h"
- fix header guard in "sync_keys.h"

92fa6c196a Rewrite logging system
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.

1efe6686fc Use config.h instead of -DHAVE_FOO=1
swiftc(1) requires every -D option to be prefixed with -Xcc, which
is not easy to achieve using autoconf.

Now instead of setting configuration macros like HAVE_LSEEK64 on the
command line using -D, they are defined in config.h, which is generated
by ./configure, ignored by Git, and included by all headers and source
files that use any configuration macro.

The dependency on Makefile has been replaced with a dependency on
Makefile.in and config.h, which helps avoid some redundant full
recompiles after running ./configure, because the configure script
does not overwrit config.h if its content does not change.

c3375d0501 Fix MDP client packet receive bug on OSX
Was failing because recvmsg(2) on OSX does not nul terminate the
pathname of local (AF_UNIX) sockets in the returned sockaddr buffer.
Zerofilling the buffer before calling recvmsg() does the trick.

In the process, improved debug and error logging, replacing
recvwithttl() with recv_message() and recv_message_frag().  The
mdp_net.c source file was retired.

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.
