Austin Clements 9d59eb0151 Make fetchint and fetchstr use proc instead of taking a struct proc 
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.

Suggested by Carmi Merimovich.

Austin Clements 2fc6c35b2f Make the ELF entry point a physical address 
This way, the bootloader doesn't have to translate the entry point.
This also makes xv6 multiboot-compliant and follows the convention
used by Linux.
