Convert code in mro_core.c to use hv_*hek() APIs where possible.
Add a macro hv_existshek() to implement exists.
The HEK-based macros are more efficient wrappers of hv_common() than the
string/length/flags macros because they also pass in the pre-computed hash
value (from the HEK). This avoids hv_common() needing to recalculate it.
