util: space-efficient MemoryMap

Browse Source 
We now use boost::icl::interval_set internally, consuming extremely
lower amounts of memory.  boost::icl was introduced with Boost 1.46;
Debian 7.0 comes with 1.49, so this dependency should be no problem
anymore.

Both the class interface and the memory-map file format stay the same.
