1aeef5d396 [srs] Support horizontal shift grids (nadgrids) in transformation. 
Relevant proj4 code was converted to C++ and Boostified. So all grids formats
are supported (ctable, ctable2, ntv1, ntv2), also vertical geoid grid GTX
format but it is not used right now. There are some differences though:
- proj4 stores loaded grids in global storage and pointers to a relevant subset
  of grids in projection parameters structure. In Boost.Geometry this is moved
  outside transformation structure to allow users to place global storage(s)
  wherever they like.
- in proj4 the grids are loaded implicitly when there is +nadgrids parameter
  passed. In Boost.Geometry an object representing a subset of grids explicitly
  has to be initialized and then passed into transforming function.
- in proj4 grids has to be "installed" into certain directories. In
  Boost.Geometry user can implement StreamPolicy opening any input stream
  having unformatted input interface. The default one uses std::ifstream
  opening files having the same names as the ones in +nadgrids parameter in
  working directory.

Added classes:
  srs::grids, srs::ifstream_policy, srs::grids_storage,
  srs::projection_grids, srs::transformation_grids
and for multithreading:
  srs::shared_grids

Added functions (also overloads)
  srs::transformation::initialize_grids(grids_storage)
  srs::transformation::forward(in, out, transformation_grids)
  srs::transformation::inverse(in, out, transformation_grids)
