*: librototiller->libtil

Largely mechanical rename of librototiller -> libtil, but
introducing a til_ prefix to all librototiller (now libtil)
functions and types where a rototiller prefix was absent.

This is just a step towards a more libized librototiller, and til
is just a nicer to type/read prefix than rototiller_.
