find_subfiles: move sub_filenames() here
Move sub_filenames() and related code from subreader.c to new file find_subfiles.c. This function is used to find subtitle files that should be loaded for the current video; this functionality is not specific to the particular kind of text subtitle handling implemented in subreader.c. Also reindent and prettify the moved code a bit.
