The sparsify function can be used to make an image sparse by replacing
runs of zeros with holes. This change adds a wrapper for the basic
rbd_sparsify function and accompanying tests.

Since the index of the registered callbacks is basically only used as
void*/unsafe.Pointer, it makes more sense and code simpler, if
the index type is uintptr instead of a simple int.

This patch changes the name to the as-agreed-upon naming from a call.
I forgot to fix this in the original patches before merging things.
Oops.

Previously, the code that set up the callbacks was doing a pretty
direct translation of go-function to c-function. It turns out this
is not needed due to the way we set up the "dynamic" go callbacks
via an integer based callback "registry". Instead, we can stay within
the C layer entirely for the C callback, passing it only the index
value and then return to the go layer through a static C function
that only needs the index value.

Right now, keeping these unexported.

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