1294770970 lua: Use a negative index for consistency 
In this case we know the size of the stack and both indexes refer to
the same position. Using a negative index is just more consistent with
the rest of the file and hopefully a bit less brittle to future
changes.

530779efb6 lua: Use a lua_slice_state instead of a from_lua_visitor 
A few places were using a from_lua_visitor only to access the
lua_slice_state member variable.

This is just a simplification. No functionality changed.

bd7593eab3 lua: Handle nil returns correctly 
With this patch lua nil values are mapped to CQL null values instead
of producing an error.

bd93a0af52 types: Return bytes_opt from data_value::serialize 
Since a data_value can contain a null value, returning bytes from
serialize() was losing information as it was mapping null to empty.

This also introduces a serialize_nonnull that still returns bytes, but
results in an internal error if called with a null value.

3d641d4062 lua: Use existing cpp_int cast logic 
Different versions of boost have different rules for what conversions
from cpp_int to smaller intergers are allowed.

We already had a function that worked with all supported versions, but
it was not being use by lua.
