ClangBuildAnalyzer reports cql3/cql_statement.hh as being one of the most expensive header files in the project - being included (mostly indirectly) in 129 source files, and costing a total of 844 CPU seconds of compilation. This patch is an attempt, only *partially* successful, to reduce the number of times that cql_statement.hh is included. It succeeds in lowering the number 129 to 99, but not less :-( One of the biggest difficulties in reducing it further is that query_processor.hh includes a lot of templated code, which needs stuff from cql_statement.hh. The solution should be to un-template the functions in query_processor.hh and move them from the header to a source file, but this is beyond the scope of this patch and query_processor.hh appears problematic in other respects as well. Unfortunately the compilation speedup by this patch is negligible (the `du -bc build/dev/**/*.o` metric shows less than 0.01% reduction). Beyond the fact that this patch only removes 30% of the inclusions of this header, it appears that most of the source files that no longer include cql_statement.hh after this patch, included anyway many of the other headers that cql_statement.hh included, so the saving is minimal.
