Because we have a finalizer configured for Conn that cleans up Ceph
resources, it's important that we don't let it get GC'd before anything
that depends on it has been cleaned up. Since clients are free to hold a
reference to an IOContext without maintaining a reference to the
underlying Conn, we hold such a Conn reference within the IOContext to
signal this dependency to the Go GC.

The previous `rados_nobjects_list_open` used for listing could not
return oids that included null characters. Although this isn't a common
case, having go-ceph able to list such objects is useful for bugs such
as https://tracker.ceph.com/issues/48874.

This struct has public fields that violate standard naming
conventions.
Disable the check on this struct only.

Now, we don't support ceph versions < nautilus this function
can move to a generic file so that nautilus specific functions
can be written here. Moved GetNamespace() and the corresponding
test function.

The GetLastVersion returns a number representing the most recent
read/write version for the io context.

The validate function works similarly to those already found
in rbd and cephfs. It will be used in future functions or
updated functions to ensure the C ioctx is ready for use.

In order to avoid external dependencies on implementation details,
this change replaces RadosError with the unexported radosError. In case
some application really needs access to the integer value, it can use
the pattern
var errno interface{ Errno() int }
if errors.As(err, errno) { ... errno.Errno() ... }

For more consisistency use getError where possible.
Changes produced using `gofmt -r 'RadosError(int(x)) -> getError(x)`,
followed by a few manual fixups.

This improves the code in two ways: first, it makes the function name and the
return type match. Second, it avoids issues found by go vet converting
from uintptr to unsafe.Pointer without any obvious pointer math.
(See: https://pkg.go.dev/unsafe)
Technically, this is an API breaking change but this function is only
public to exchange the internal ceph structure between the rados and
rbd modules. This had the smallest delta and doesn't feel any more
hacky than what already existed in the code. If someone was using this
function externally then too bad.

Create an object_iter.go from the Iter related functions that were
formerly in ioctx.go. This makes ioctx a little less of a giant wall of
code as well as making things easier to work on in the future.

RadosError-prefixes are not recommended, instead just Err as prefix is
used.
Also, errors are constants, not variables.
For existing users, backwards compatible constants are available. These
will need to be removed in a future go-ceph release.

There is no good reason why the internal error handling support should
be exposed outside the rados package. Make the function lower-cased and
thus private.
