[1/3] util/cutils: Move size_to_str() from "qemu-common.h" to "cutils.h"

Commit Message

The size_to_str() function doesn't need to be in a generic header.

It makes also sens to find this function in the same header than
the opposite string to size functions: qemu_strtosz*().
Note than this function is already implemented in util/cutils.c.

Since we introduce a new function in a header, we document it,
using the previous comment from the source file.
