Import a few updates to nvme.h from nvme-cli. This mostly includes a few
new fields and error codes, but also a few renames that so far are only
used in user space. Also one field is moved from an array of two le64
values to one of 16 u8 values so that we can more easily access it.

The host is allowed to issue identify as many times
as it wants, we need to stay consistent when reporting
the serial number for a given controller.

This patch introduces a implementation of NVMe subsystems,
controllers and discovery service which allows to export
NVMe namespaces across fabrics such as Ethernet, FC etc.
The implementation conforms to the NVMe 1.2.1 specification
and interoperates with NVMe over fabrics host implementations.
Configuration works using configfs, and is best performed using
the nvmetcli tool from http://git.infradead.org/users/hch/nvmetcli.git,
which also has a detailed explanation of the required steps in the
README file.
