maps: add the "branchmaxrevnum" method to RevMap
Iterating the RevMap can be very expensive for large repos. To prevent future
code from iterating the possibly huge RevMap causing performance issues, it's
a good idea to clean all iterating code outside RevMap.
This patch adds a method used by "get_parent_svn_branch_and_rev".
In the future, we will have a SqliteRevMap, which will have an efficient
implementation for this query, and it will disable "__iter__" to prevent
future performance issues.
