These functions can be used to query or modify the variables in a
given configuration. No sanity checking is done on the variable names.
This is mostly meant as an API preview.

If cfg_readline consumes the line, then parse_section_header will read
past it and if we read a character, parse_variable won't have the full
name.
This solution is a bit hackish, but it's the simplest way to get the
code to parse correctly.

Save the location of the name in section_out instead of returning it
as an int. Use the return code to signal success or failure.
