Eric Anholt 4c9a200725 glamor: Allow nested mapping of pixmaps. 
The common pattern is to do nested if statements making calls to
prepare_access() and then pop those mappings back off in each set of
braces.  Some cases checked for src == dst to avoid leaking mappings,
but others didn't.  Others didn't even do the nested mappings, so a
failure in the outer map would result in trying to umap the inner and
failing.

By allowing nested mappings, we can fix both problems by not requiring
the care from the caller, plus we can allow a simpler nesting of all
the prepares in one if statement.

v2: Add a comment about nested unmap behavior, and just reuse the
    glamor_access_t enum.
