Major `cat` improvements
`simplecat()` is a function for printing files smaller than the systems
page size, mmaping these files would be pointless. Also used for stdin.
`fastcat()` is `splicecat()` on Linux, it utilizes the `splice(2)`
syscall. On other platforms it is `mapcat()` which utilites the
`mmap(2)` syscall. This is only worth the performance boost for
files larger than the systems page size, otherwise it can be a
performance hit.
