Update ccan/structeq. 

structeq() is too dangerous: if a structure has padding, it can fail
silently.

The new ccan/structeq instead provides a macro to define foo_eq(),
which does the right thing in case of padding (which none of our
structures currently have anyway).

Upgrade ccan, and use it everywhere.  Except run-peer-wire.c, which
is only testing code and can use raw memcmp(): valgrind will tell us
if padding exists.

Interestingly, we still declared short_channel_id_eq, even though
we didn't define it any more!

There are a few subtleties you should be aware of as you modify deeper
parts of the code:
* `structeq` will not work on some structures.
For example, it will not work with `struct short_channel_id` --- use
`short_channel_id_eq` for comparing those.
* `ccan/structeq`'s STRUCTEQ_DEF will define safe comparison function foo_eq()
for struct foo, failing the build if the structure has implied padding.
* `command_success`, `command_fail`, and `command_fail_detailed` will free the
`cmd` you pass in.
This also means that if you `tal`-allocated anything from the `cmd`, they
