Make .o files in separate subdirectories for servald and library
Factor struct __sourceloc and __WHENCE__ from "log.h" into "whence.h"
Factor sid_t etc from "serval.h" into "serval_types.h"
Factor rhizome_bid_t etc from "rhizome.h" into "rhizome_types.h"
Do not include "serval.h" in library sources
Add log_stderr.c and logMessage.c for stand-alone executables
Remove two redundant calls to rhizome_retrieve_manifest() in meshms.c,
revealed by an assert() in the stricter manifest parsing code
Fix header files included by socket.h
Move config-dependent code (recvwithttl) from net.c to mdp_net.c (new)
Move log-implementation-independent code from log.c to log_util.c (new)
Build config_test binary in Makefile
Remove stowSid() at last
Change API of tohex() and strbuf_tohex(), to pass string length instead of
binary byte count. This allows odd numbers of hex digits to be produced.
Remove alloca_tohex_sid(); replace with alloca_tohex_sid_t()
New alloca_tohex_sid_t_trunc() macro
Upgrade configuration schema macros to allow optional "default label"
argument to SUB_STRUCT and VALUE_SUB_STRUCT elements.
New STRUCT_DEFAULT section declares alternative STRUCT default values
with a label.
Introduce CFINCOMPATIBLE config parse result flag.
Sort interface rules by unsigned integer key.
Legacy and modern 'interfaces' config styles are now incompatible.
Validate config_network_interface struct to enforce that only exactly one of
'match' and 'dummy' options are set.
Add test cases for 'interface' config option.
Config Object Model parser now returns bitmask result of CFxxx flags and only
allocates root node if the config file is non-empty.
Added emalloc_zero().
