Golint wants to rename the struct. I think the name is fine. I
can disable golint. Golint will no longer complain about the
name.

Move SHM specific code into a subpackage. Within the main locks
package, move the manager to be linux-only and add a non-Linux
unsupported build file.

Check value of semaphores when incrementing to ensure we never go
beyond 1, preserving mutex invariants.
Also, add cleanup code to the lock tests, ensuring that we never
leave the locks in a bad state after a test. We aren't destroying
and recreating the SHM every time, so we have to be careful not
to leak state between test runs.
