506518ad06 Allow interfaces to use local unix addresses 
- broadcast packets are sent to all sockets in the same folder
- switched most tests to use local sockets

30b2059608 Fix -Wunused-parameter warnings 
New UNUSED(param) macro suppresses the warning for a specific parameter

In some cases, removed the unused parameters.  In others, used the
parameter in a DEBUGF() or assert() statement to document the intent.

Remove two redundant calls to rhizome_retrieve_manifest() in meshms.c,
revealed by an assert() in the stricter manifest parsing code

a9ccd38adc Improve overlay buffer ob_xxx() primitives 
All ob_append_xxx(b,...) functions return void

ob_makespace() returns 1 if successful, 0 if not

Add ob_overrun(b) predicate to check for overrun after any number of
appends

a95ef79139 Use sid_t everywhere 
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

c9f9025581 Fix intermittent 'routing' test failures 
Caused by tests running so slowly that nodes become unreachable due to
timeout before the assertion of reachability is made.  The timeout was
hard coded at five times the tick interval (2.5 seconds).

Introduced new config options: mdp.iftype.*.reachable_timeout_ms and
interface.*.mdp.reachable_timeout_ms to allow the timeout to be
configured.  Configure the timeout to 60 seconds in 'routing' tests.

Changed the config schema to move options interfaces.*.mdp_tick_ms and
interfaces.*.packet_interval into interfaces.*.mdp.tick_ms and
interfaces.*.mdp.packet_interval (introduced new sub-struct 'mdp').
