Simon Kelley 4bf46ceb37 Add the ability to bail before EOF to get_line_alloc();
If we stop reading a file before getting to the end, get_line_alloc()
will not clean up the memory it allocated. Give get_line_alloc()
the ability to do a forced cleanup by calling it with a NULL file,
and use that ability where we stop reading a file early.

Also clear the state variables when we free the memory, to
pre-empt use-after-free.
