Paweł Bylica 66b2ae9663 EVM-C: return by explicit output param 
In evm_query_fn, return result by explicit output parameter to avoid C ABI issues and inrease portability. C compiler would do the same implicitly.

Paweł Bylica 575337b449 EVM-C: pass callback argument explicitly by pointer 
We try to avoid C ABI complex rules like passing structs by value to increase portability.

Paweł Bylica 3d2e365661 EVM-C: introduce factory -- simpler interface 
Replace evm_interface with evm_factory. The factory provides ABI protection and the function for creating EVM instances. After the instance is create you can discard the factory as it is no longer needed.

Paweł Bylica bfd39abfb2 EVM-C: Drop address field from evm_result 
The evm_result was planned to be used as the return struct of the call callback. The address was added to support CREATE, but it is never used and the union here confuses many languages like Go and Python.

Delegating CALL cost calculations to Env is bad idea and has bugs.

Paweł Bylica 5defa1d222 EVM-C: Support multiple implementation 
Support multiple VM implementations by EVM-C in a single application by exporting only a function table (like vtable in OOP) for each implementation. The symbol name convention is `<vm-name>_get_fn_table()`.

Paweł Bylica a4bb85250d EVM-C: allow correct symbol exporting 
This is a bit strange but MSVC requires dllexport spec to be applied to some (not all) function declarations. So the evm.h header will now use EXPORT macro for that if that macro is defined by the implementation.
