Remove unecessary locking, mostly from places where a read is done of a
value that can't ever be in an inconsistant intermediate state even when
some other thread is in the middle of writing the value/register.
Locking of the hardware remains in the few places that do r-m-w operations.
Locking of metadata access is restricted to places using memcpy or sprintf
to modify the metadata.
