Build cgo files with -Wall -Werror
To avoid unnecessary warnings and errors in the future I'd like to
propose building all cgo related sources with `-Wall -Werror`. This
commit fixes some warnings which came up in `shm_lock.c`, too.

Matthew Heon faae3a7065 When refreshing after a reboot, force lock allocation
After a reboot, when we refresh Podman's state, we retrieved the
lock from the fresh SHM instance, but we did not mark it as
allocated to prevent it being handed out to other containers and
pods.

Provide a method for marking locks as in-use, and use it when we
refresh Podman state after a reboot.

Fixes #2900

Matthew Heon 7fdd20ae5a Add initial version of renumber backend
Renumber is a way of renumbering container locks after the number
of locks available has changed.

For now, renumber only works with containers.

Matthew Heon a21f21efa1 Refactor locks package to build on non-Linux
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.
