/*
**  READCF -- read configuration file.
**
**	This routine reads the configuration file and builds the internal
**	form.
**
**	The file is formatted as a sequence of lines, each taken
**	atomically.  The first character of each line describes how
**	the line is to be interpreted.  The lines are:
**		Dxval		Define macro x to have value val.
**		Cxword		Put word into class x.
**		Fxfile [fmt]	Read file for lines to put into
**				class x.  Use scanf string 'fmt'
**				or "%s" if not present.  Fmt should
**				only produce one string-valued result.
**		Hname: value	Define header with field-name 'name'
**				and value as specified; this will be
**				macro expanded immediately before
**				use.
**		Sn		Use rewriting set n.
**		Rlhs rhs	Rewrite addresses that match lhs to
**				be rhs.
**		Mn arg=val...	Define mailer.  n is the internal name.
**				Args specify mailer parameters.
**		Oxvalue		Set option x to value.
**		O option value	Set option (long name) to value.
**		Pname=value	Set precedence name to value.
**		Qn arg=val...	Define queue groups.  n is the internal name.
**				Args specify queue parameters.
**		Vversioncode[/vendorcode]
**				Version level/vendor name of
**				configuration syntax.
**		Kmapname mapclass arguments....
**				Define keyed lookup of a given class.
**				Arguments are class dependent.
**		Eenvar=value	Set the environment value to the given value.
**
**	Parameters:
**		cfname -- configuration file name.
**		safe -- true if this is the system config file;
**			false otherwise.
**		e -- the main envelope.
**
**	Returns:
**		none.
**
**	Side Effects:
**		Builds several internal tables.
