Use 'fp' name for local 'FILE*' variables.

It is inappropriate to use the 'fd' name for 'FILE*' variables.
POSIX file descriptiors are of type 'int' and are distinguished from
ISO C stream pointers (type 'FILE*').

Rename these variables to 'fp', which is a preferred naming in POSIX.
(Note that ISO C preferred the 'stream' name for the variables.)
