HBASE-9142 Mutation#getFamilyMap() return type change between HBase 94 and 96 breaks downstream apps

For 0.95/0.96, we need to preserve the getFamilyMap signature through a deprecation cycle.  The new
method needs to be present alongside the old in 0.95, so we rename the method with the new signature
to getFamilyCellMap() in both trunk and 0.95, and restore a deprecated version of the old in 0.95.
