Add SplitBuffer and SplitSparseBuffer functions for extracting a list
of strings from a single buffer, typically returned in C code, from
a single Go buffer. The SplitBuffer variant will return empty strings
if multiple nulls are found in sequence, assuming that the C code
packs data between on single null byte (expect the final byte).
The SplitSparseBuffer variant assumes that the C code may not
tightly pack the data with single null bytes and thus will not
return any empty strings (unless the input buffer is empty
or only contains nulls).
Most of the code in the go-ceph codebase is doing the latter but
probably should have been doing the former. Thus both approaches
are provided.

Add UpdateWatch function implementing rbd_update_watch.
Add Unwatch function implementing rbd_update_unwatch.
Add a higher level Watch type to encapsulate watching
the image and the watch handle.
Add basic tests to validate the callback behavior.

In order to avoid external dependencies on implementation details,
this change replaces CephFSError with the unexported cephFSError. 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() ... }

On octopus taking in the -devel packages causes *some* of the packages
to be updated but not all. This apparently makes ceph-fuse fail to
start correctly by blocking forever. This works around that issue.

There are functions from librbd that can use the Timespec type too.
Instead of consuming 'cephfs.Timespec' in the rbd package, create an
internal type that can be exposed through both packages.
This looks a bit like duplication, but it does not break the current
users of Timespec in the cephfs package.

I noticed that the make target I use for smoke testing things locally
was failing due to new octopus related vars. This was due to the go test
lines in the makefile not passing tags for the maximum ceph version.

After having forgot to explicitly pass CONTAINER_CMD for the millionth
time I figured copying ceph-csi a smidgen and automatically selecting
podman or docker based on availability would be save me some typing.

rbd_namespace_create() function creates namespace for a given iocontext.
rbd_namespace_exists() function checks whether the given namespace exists or not.
rbd_namespace_remove() function removes the given namespace.

Add wrappers for ceph_fsync. The Fsync call directly wraps ceph_fsync
which provides options to behave more like fsync or more like fdatasync.
Add Sync, a simpler wrapper over Fsync, to match any interfaces that
make use of `File.Sync` from Go's os package.

These private functions with names like monCommand and pgCommand were no
different from the public xxxCommandWithInputBuffer commands. Thus the
redundant private functions are removed to simplify the file. As private
functions these can be added back later w/o fuss if the behavior of
the xxxCommand and xxxCommandWithInputBuffer calls need to differ more
in the future.
