tools: don't abort on malformed documentation lines.
Rusty Russell authored

ccanlint would abort with 'Malformed line 53' if there was a bad header.
That's very poor, and deeply unhelpful.

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).
