The types 'size_t' and 'unsigned long' have been used randomly for the uaccess functions. This looks rather confusing. So let's change all functions to use unsigned long instead and get rid of size_t in order to have a consistent interface. The only exception is strncpy_from_user() which uses 'long' since it may return a signed value (-EFAULT).
