duplicate symbol error when linking contracts consisting of multiple .cpp files

[arhag]

The EOSIO.CDT eosiolib header files include implementations of certain functions, such as eosio::send_deferred, in the header files. When trying to link a contract consisting of multiple cpp files that each include those problematic header files (such as transaction.hpp), the linker gives a duplicate symbol error.
