554: Better errors on when missing to lock shared resources r=perlindgren a=korken89

Old error:

```
error[E0614]: type `value<'_>` cannot be dereferenced
  --> examples/lock_minimal.rs:33:9
   |
33 |         *c.shared.value += 1;
   |         ^^^^^^^^^^^^^^^

```

New error:

```
error[E0614]: type `value_that_needs_to_be_locked<'_>` cannot be dereferenced
  --> examples/lock_minimal.rs:33:9
   |
33 |         *c.shared.value += 1;
   |         ^^^^^^^^^^^^^^^

```
