Do not include closeout.h.

(xfopen): Use stdout if *how != 'r'.
(mergefps): Remove FPS arg.
Open all input files, and close all files when done.
If OFP is null, open the output file (but after opening input files).
All callers changed.
(first_same_file): New function.
(sort, merge): Remove arg OFP; we now open the output file as needed.
All callers changed.
(merge): New arg MAX_MERGE.  All callers changed.
(sort):	For "sort F -o F", close the input before opening the output.
(main): Do not use close_stdout; 'sort' and 'merge' now close stdout.
(This also fixes a close-stdout-twice bug.)
Remove test for overlapping input and output files, as 'sort' no longer
needs to worry about overlap, and 'merge' checks for overlap itself.
Use first_same_file to inform 'merge' about how much to merge at
the top level, to avoid overlap.
