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').

9ba08e465f Issue #11: use socklen_t instead of int where appropriate

41e18e587d Issue #69: replace sqlite3_bind_xxx() calls
Use the new sqlite_bind() and sqlite_prepare_bind() calls instead.

Add cmp_sid_t() function, use it instead of memcmp().

Use alloca_tohex_sid_t() in preference to alloca_tohex_sid() when the
argument is a sid_t.

cc96e08e9d Issue #20: Improve socket name handling
The recently added cmp_sockaddr() function does not call stat(2) any
more to compare local AF_UNIX socket address paths, so not it is stable
enough to use for ordering sockaddr structs.

New function: real_sockaddr() converts the file path of a local AF_UNIX
file socket using realpath(3).  The MDP client uses it on the sender
address of every MDP reply packet it receives to ensure that symlinks in
the instance path do not cause MDP client failures.

Rename recently added socket_setname() function: make_local_sockaddr().

ae61a4f35c Issue #20: Make abstract sockets work
Finish the work started by Daniel in 2012, by using abstract local
AF_UNIX sockets on platforms that support them (Linux, Android).

Fix all sorts of bugs and issues that prevented the existing MDP and
Monitor client and server code from working with abstract socket names.

4937757d36 Improve Serval instance path operations
Replace form_serval_instance_path(), which takes a single 'path'
argument, with formf_serval_instance_path() and
vformf_serval_instance_path(), which take printf(3)-like arguments.
This supports more flexible instance path file names.

FORM_SERVAL_INSTANCE_PATH() macro works as before, but reimplemented
