Subject: [PATCH] exec: introduce struct user_arg_ptr

No functional changes, preparation.

Introduce struct user_arg_ptr, change do_execve() paths to use it
instead of "char __user * const __user *argv".

This makes the argv/envp arguments opaque, we are ready to handle the
compat case which needs argv pointing to compat_uptr_t.
