** 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.
