Rusty Russell 91a22dc496 jsonprc: make json_get_params() fail the command, for better error reporting.
We move it into jsonrpc where it belongs, and make it fail the command.
This means it can tell us exactly what was wrong.

* Add port parsing support to parse_wireaddr. This is in preparation for storing
addresses in the peers table. This also makes parse_wireaddr a proper inverse of
fmt_wireaddr.

* Move parse_wireaddr to common/wireaddr.c this seems like a better place for
it. I bring along parse_ip_port with it for convenience. This also fixes some
issues with the upcoming ip/port parsing tests.

Rusty Russell bbac67f108 withdraw_tx: don't create empty output if no change.
We were using changekey as the flag to produce change, not changesat,
but the caller was using changesat as the flag.

Also, don't allocate changekey at all if we don't need it; this means
valgrind will complain if we use it at all, too.

Christian Decker ee25547576 Re-enable builds with DEVELOPER=0
Two changes:
 - Fixed the function signature of noleak_ to match in both
   configurations
 - Added memleak.o to linker for tests

Generating the stubs for the unit tests doesn't really work since the
stubs are checked in an differ between the two configurations, so
adding memleak to the linker fixes that, by not requiring stubs to be
generated in the first place.

Rusty Russell c956d9f5eb lightningd: tal memleak detection, dev-memleak command.
This is a primitive mark-and-sweep-style garbage detector.  The core is
in common/ for later use by subdaemons, but for now it's just lightningd.
We initialize it before most other allocations.

We walk the tal tree to get all the pointers, then search the `ld`
object for those pointers, recursing down.  Some specific helpers are
required for hashtables (which stash bits in the unused pointer bits,
so won't be found).

There's `notleak()` for annotating things that aren't leaks: things
like globals and timers, and other semi-transients.
