Brian Gianforcaro 4cee441279 Kernel: Combine validate and copy of user mode pointers (#1069) ...

Right now there is a significant amount of boiler plate code required
to validate user mode parameters in syscalls. In an attempt to reduce
this a bit, introduce validate_read_and_copy_typed which combines the
usermode address check and does the copy internally if the validation
passes. This cleans up a little bit of code from a significant amount
of syscalls.
