Support for general binding and parsing any types

[Kulezi]

• Added support for binding any type with use of gocql.Marshal
• Added support for scanning any type with use of gocql.Unmarshal
• Binding to unprepared queries can now be done only with type-specialized methods
• Incorrect binding will now return an error on query execution
• Added benchmarks comparing conversions using general and concrete methods, results:

I think this will be needed to make a compatibility layer for gocql and gocqlX, benchmarks show that it's much slower than concrete bindings, however I can barely see any difference with make run-benchtab, maybe because of the driver having spare time due to waiting on syscalls.

This will be used in a separate package providing gocql compatibility.
