ltp: use C function prototypes in "iogen.c"

Many functions in "iogen.c" are defined using old-style C
declarations.  Convert all functions so they follow standard C,
and include standard prototypes for each.

Every function (except main()) now has a standard C prototype, and
all prototypes are grouped in the same section of the file.  The
prototypes--as well as the function definitions themselves--now
follow a consistent formatting style.
