  1. std: Clamp max read/write sizes on Unix 

    Turns out that even though all these functions take a `size_t` they don't
actually work that well with anything larger than the maximum value of
`ssize_t`, the return value. Furthermore it looks like OSX rejects any
read/write requests larger than `INT_MAX - 1`. Handle all these cases by just
clamping the maximum size of a read/write on Unix to a platform-specific value.

Closes rust-lang#38590
