Paweł Dziepak 95e97463d2 kernel: add generic wrapper for accessing user memory ...

This patch adds user_access() which can be used to gracefully handle
page faults that may happen when accessing user memory. It is used
by arch_cpu_user{memcpy, memset, strlcpy}() to allow using optimized
functions from the standard library.

Currently only x64 uses this, but nothing really is arch specific here.
