mdocml: The files mandoc.c and mandoc.h contained both specialised

[schwarze@mdocml.bsd.lv]

Log Message:
-----------
The files mandoc.c and mandoc.h contained both specialised low-level
functions used for multiple languages (mdoc, man, roff), for example
mandoc_escape(), mandoc_getarg(), mandoc_eos(), and generic auxiliary
functions.  Split the auxiliaries out into their own file and header.

Added Files:
-----------
    mdocml:
        mandoc_aux.h
        mandoc_aux.c
