I have been looking on the net to see if there are any traces of code
using those macros, but could not find any.  The last trace of a macro
use is in 8ebe1e3, which just relies on GET_STRING_RELOPTION_LEN.  So
it looks rather convincing now to just remove this code.  Attached is
a patch for that.  There could be an argument for keeping
GET_STRING_RELOPTION actually which is still useful to get a string
value in an option set using the stored offset, and we have
the recently-added dummy_index_am in this category.  Any thoughts?
