Adds types to work with the ceph cluster (the admin type) and a type

As per go-ceph issue #427, and a discussion in #399 this change and
test ensure that the cephIoctx helper function, that extracts the
C.rados_ioctx_t from a Go rados.IOContext, never returns a nil/null
C type.
As these are always "programming errors" panicking is reasonable
behavior for this case.

Using WriteSame() to implement a zerofill function is less straight
forward than expected. `rbd_discard_on_zeroed_write_same` is a Ceph
option than affects the behaviour of WriteSame(). By default the option
is enabled, causing WriteSame() to call discard instead of writing
zeros.

Although it seems to be stable with the current Go versions,
unsafe.Pointers that are created by applying arithmetic on nil
pointers are explicitly not allowed[1], and could potentially lead to
panics by the garbage collector. To be on the safe side, this change
goes back to minimal inline wrappers for the callback registrations,
which should be zero-cost. For the callbacks themselves fortunately
no wrappers are required, because CGo happily converts void* to
uintptr arguments. The potentially problematic VoidPtr helper is
removed again.

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.
