file_lines_parse() plays horrible tricks with
the passed-in talloc pointers and the hierarcy
which makes freeing hard to get right.
As we know mem_ctx is freed by the caller, after
calling file_lines_parse don't free on exit and let the caller
handle it. This violates good Samba coding practice
but we know we're not leaking here.
