So far only happens during normal shutdown, but it may happen in other
cases as well. We simply define a new destructor that unregisters the
`cmd` from the `jcon`.

These were fun to hunt down. The jcon and the conn are allocated off
of ld, so the free order is unspecified and if conn is freed before
conn then the finish_jcon destructor uses conn after free.
[ Edit: split commit, modified to use a destructor directly on jcon,
which is more robust than relying on it only being freed via conn --RR ]

Some fields were redundant, some are simply moved into 'struct lightningd'.
All routines updated to hand 'struct lightningd *ld' now.

Also, we split the more sophisticated json_add helpers to avoid pulling in
everything into lightning-cli, and unify the routines to print struct
short_channel_id (it's ':', not '/' too).
