This patch is the folded version of API updates, along with the associated tool
changes to ensure that the build is always consistent.
API updates:
- The source domain in the sharing calls is no longer assumed to be dom0.
- Previously, the mem sharing code would return an opaque handle to index
shared pages (and nominees) in its global hash table. By removing the hash
table, the handle becomes a version, to avoid sharing a stale version of a
page. Thus, libxc wrappers and tools need to be updated to recall the share
functions with the information needed to fetch the page (which they readily
have).
Tool updates:
The only (in-tree, that we know of) consumer of the mem sharing API is the
memshr tool. This is updated to use the new API.
