Make struct_bl and struct_bd into pointers. This removes the need to do

copying on internals after modification.  Even more importantly, if an
ENDBODY token is provided, it would have been impossible for post-change
copying of the data to take place in the BLOCK.  This allows it to
happen by dint of pointers.

Also did some bikeshedding in mdoc_term.c: checking against enum type
and explicitly casting to the "post" function to void.  This is for my
own readability.
