When obtaining the device for a pointer, we currently rely on an attribute which only became available with CUDA 9.2 ; but we could, in fact, obtain the context handle, then obtain its device ID using a second API call. Let's do that to support CUDA 9.1 and earlier.

Fixes #462, fixes #463: Pointer-related functions:
dad8336 
* Can now get the device for a pointer in CUDA before 9.2 - by getting the context, then getting the device for the context
* Added `memory::device_of()` and `memory::context_of()`
* Added `memory::detail_` functions for returning the context handle or device id of a pointer, without having to remember the pointer attributes mechanism
