Add support for associating an XRC domain to an inode so that XRC
domains can be shared between processes. We keep a per-device RB tree
of XRCDs (indexed by inode) in the uverbs module, and use struct
ib_xrcd's usecnt member to reference count XRCDs so that an XRCD is
not

Thanks. Yes, this was all compile-tested only.
