Split the document parsing sequence out of main.c and into read.c,

putting the interface into mandoc.h.  This effectively makes the
function of main.c be command-line handling, invoking the parser, and
sending its output to the output handler.  The sequence of parsing
(pfile(), pdesc(), etc.) has changed very little but for clean-up of
some state variables (curp->fd, etc.).
