This makes compatability with old verbs easier, and means you can
detect if the verbs_device is present based only on an 'ibv_device
*' pointer, this is more flexible going forward.

ibverbs could always export an extended device through a
compatibility layer, similar to what I added in patch 2.

We only get one chance to re-use the alloc_contex entry as an
extension flag, and this is it. What is here is fine for the two
functions added but if we want a new device function in future that is
not tied to a context (eg query_device_capabilities_ex, say) then we
are pretty stuck.
