THRIFT-2189 add union support for go generator
Client: Go
Patch: Anton Lindström <lindztr@gmail.com> and Jens Geyer

This closes #369

This makes it possible to check if a field  is set and skips adding new ones.
Fields in unions are pointers by setting them as `t_field::T_OPTIONAL`.

To be sure that exactly one and only one field is set in a union, we count the
number of fields set and return an error if not exactly one field is set.

This is a breaking change and will require fields in unions to be passed in as
pointers.
