Continue parser unification:

* Make enum rofft an internal interface as enum roff_tok in "roff.h".
* Represent mdoc and man macros in enum roff_tok.
* Make TOKEN_NONE a proper enum value and use it throughout.
* Put the prologue macros first in the macro tables.
* Unify mdoc_macroname[] and man_macroname[] into roff_name[].
