1. rados_ioctx_snap_lookup()
2. rados_ioctx_snap_get_name()
3. rados_ioctx_snap_get_stamp()

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.

Previously, ParseCmdLineArgs was the function directly wrapping the
ceph rados_conf_parse_argv function. This function has the improper
(IMO) behavior of assuming you didn't know your own argv[0] and just
always stuck "placeholder" in argv[0]. This function adds a more
direct wrapper ParseConfigArgv that allows the caller to pass an
full argv, and they can put any placholder value desired if they want.

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() ... }

These functions wrap rados_mon_command_target and allow the user to send
"command JSON" to specific MONs.

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.

The *_command functions in librados and libcephfs document the use
of specific free functions for data allocated. These functions are
currently just wrappers around C's free() function. However, to be
more strictly compliant this change adds a free-function callback
to the CommandOutput type and the specific free functions are now
used outside the unit tests.

Replace the argument handling (wrangling?) around *_command functions,
such as MonCommand, with the new command input and output helper types
from the internal/cutil package.
No external change should be visible.

It appears that ceph octopus (currently testing as master) is stricter
about some inputs and the old formatting in the test was failing.
Use formatting that all versions should be happy with.

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.

Moving the errutil pkg to "internal/errutil" makes errutil private-like
and accessible to only other go-ceph packages. The functions it provided
were always meant to be used only by go-ceph, this just makes it more
official. This is a breaking change but it was only available to
outside users for 1 release and it is somewhat doubtful users outside
of go-ceph would have reached for these functions.

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.
