Fix long-standing confusion between Files and Strings

Browse source 
Don't use "f_" prefix and "File *" type for the variables that are
strings and not files. Use "sect_" prefix, which means "section", and
"String *" for them.

This finally stops using misleading types (even if they all map to
"void*" anyhow) for the variables, which could result in using file-only
functions with non-files or string-only functions (e.g. Append()) with
two "f_" variables, only for it to work with one of them but not the
other (which was a real file, unlike the first one).

No real changes, this just clarifies the types.
