Struct-ifying file_status

Struct-ifying file_status

Hi,

I'm slowly moving the file-read and pre-parsing main.c stuff into its 
own file.  Unfortunately, there's lots of goo in these files and this 
will take some care.  Any objections to this first patch, which makes 
file_status local to struct curparse?
