BBHandler: Error for incomplete function definitions

Add some sanity checks on the parsing state engine when returning data
so that incomplete functions raise parse errors.

This means a recipe doing:

do_somefunction {
     echo 1

VAR = "1"

will now raise a ParseError. To get the right file/line information,
__infunc__ was changed to a list.
