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.

This is not a child of cmd, since they have independent lifetimes, but
we don't want to noleak them all, since it's only the one currently in
progress (and its children) that we want to exclude.

We use the tal notifiers to attach a `backtrace` object on every
allocation.
This also means moving backtrace_state from log.c into lightningd.c, so
we can hand it to memleak_init().

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.
