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.

8db5f9c14a Merge branch 'anyservice' into 'development' 
Allows any valid "service" manifest field in the "rhizome add file"
command

Many improvements in Rhizome manifest parsing; stricter manifest syntax
rules (no comment or blank lines, field names must be alphanumeric
identifiers), faster preliminary manifest inspection when receiving
manifest advertisements or syncing manifests

The 'development' branch introduces "struct socket_address" which
coincidentally fixed the recently encountered Linux kernel 3.12
recvmsg(2) EINVAL problem, so that 'rhizomeprotocol' tests which fail on
the 'anyservice' branch will pass after this merge

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').
