RDMA/core: Create mmap database and cookie helper functions
Create some common API's for adding entries to a xa_mmap. Searching for an entry and freeing one. The general approach is copied from the EFA driver and improved to be more general and do more to help the drivers. Integration with the core allows a reference counted scheme with a free function so that the driver can know when its mmaps are all gone. This significant new functionality will be helpful for drivers to have the correct lifetime model for mmap objects.
