tree: fail on non-negative return values from parse_and_open
Currently, we see a warning with specific compilers:
../nvme/nvme.c: In function 'ns_rescan':
../nvme/nvme.c:4389:19: warning: 'dev' may be used uninitialized in this function [-Wmaybe-uninitialized]
This is due to a theoretical failure path in parse_and_open(), where
argconfig_parse() returns a positive value - this would require the
global errno to be negative.
Even though the unintialised use of dev is only possible with negative
error (which shouldn't happen), we should still consider any non-zero
return value of parse_and_open a failure. This change fixes the
instances of:
err = parse_and_open(...);
if (err < 0)
changing to:
err = parse_and_open(...);
if (err)
... and also applies this to the single use of open_exclusive().
The positive return values from parse_and_open() were removed in 11542bbd; beforehand, parse_and_open() would return a fd.

tree: Add NVMe-MI support
Now that we have a struct containing the NVMe device file descriptor, we
can abstract this to support different transport types.
This change adds support for NVMe-MI transports, by adding a `mi` member
to struct nvme_dev's union, and allowing devices to be specified by an
MCTP address:
mctp:<network>,<endpoint-id>:<controller-id>
- where the `controller-id` is optional, and defaults to 0 if not
specified.
For this, we need to add suitable linkage to the libnvme-mi component of
the libnvme codebase.
None of the actual commands can use the MI transport at present, as they
currently assume access to dev->direct.fd. We will add facilities for
that in upcoming changes.

tree: Combine NVMe file descriptor into struct nvme_dev
Currently, our references to the nvme device are fragmented: we have the
device name and stat buf stored in the global nvme_dev, and then a
separate nvme device file descriptor passed between functions
This change moves the fd into the struct nvme_dev:
struct nvme_dev {
+ int fd;
struct stat stat;
const char *name;
};
and changes parse_and_open to now populate a pointer to the dev on
successful return. Callers can now access the fd through dev->fd,
unifying this with the name and statbuf.
[At the moment, this just uses the global nvme_dev variable, but we'll
make that neater in a future change]
There are a large number of functions that use the fd directly, hence
the size of this patch. I've attempted to make this as atomic as
possible, but there are some call sites which warrant some reformatting
as we go here.
There may be some future opportunities to pass around the struct
nvme_dev * rather than the fd, but this change just implements the
minimal change to group our nvme device into the one struct.
