txshift: switch to uint for workers
workaround missing size_t implementation of
po::value_semantic* create_value(T& val, const std::string& arg)
as it would conflict with when size_t == unsigned int even when
it would help for size_t == unsigned long

> The reason is that the workers atribute is declared as size_t and size_t is
> defined as unsigned long (as opposed to the usual unsigned int) and there is
> no instance of qpid::optValue() for size_t/unsigned long. The solution would
> be to add
> template QPID_COMMON_EXTERN po::value_semantic* create_value(size_t& val,
> const std::string& arg);
> in src/qpid/Options.cpp, but I think it would conflict with existing
> create_value() functions, at least I recolled such problems from other
> projects.
> The workaround is to declare workers as uint in txshift.cpp.
