Make fetchint and fetchstr use proc instead of taking a struct proc

Browse source 
Previously, these were inconsistent: they used their struct proc
argument for bounds checking, but always copied the argument from the
current address space (and hence the current process).  Drop the
struct proc argument and always use the current proc.
