Make it clear what arguments are expected in RTLM7, RTLM8 and improve phrasing in RTLM7*, RTLM8*, RTLM6d1a and RTLM6d1b

This uses phrasing initially added in 652daac commit
in #343 PR. It makes sense to
include those changes in this #333 PR
to make the OBJECT sync sequence and related spec items more clear.
