libxc: add xc_gnttab_map_grant_ref_notify
Normally, when a userspace process mapping a grant crashes, the domain
providing the reference receives no indication that its peer has
crashed, possibly leading to unexpected freezes or timeouts. This
function provides a notification of the unmap by signalling an event
channel and/or clearing a specific byte in the page.
This also unifies the 3 very similar grant-mapping osdep interfaces into
a single function instead of introducing yet another minor variation.
