Make tdesc_reg string fields std::string

Make the name, group and type fields of tdesc_reg std::strings.  This
way, we don't have to manually free them in ~tdesc_reg.

Doing so results in a small change in the generated tdesc.  Instead of
passing an empty string for the group parameter of tdesc_create_reg, the
two modified tdesc now pass NULL.  The end result should be the same.
