So add a flag to queue_limits. Signed-off-by: Kent Overstreet <kmo@daterainc.com>

This reworks the reserves so we've got separate freelists for each reserve instead of watermarks, which seems to make things a bit cleaner, and it adds some code so that btree_split() can make sure the reserve is available before it starts.
