rustyrussell tal: allow notifiers on NULL.
A destructor on NULL doesn't make sense, but notifiers (eg. new children)
do.  We fix up a mistake in run-notifier (comparing ctx with itself) and
loose typing in tal.c's tal_add_notifier_ too.

You can find a set of helper utilities under tools/ and the modules
under ccan/.  The recommended way to add ccan modules to your project
is to create a ccan/ directory and add one module per subdirectory
(see tools/create-ccan-tree).
