Find a buffer, by name. Return a pointer
to the BUFFER structure associated with it. If
the named buffer is found, but is a TEMP buffer (like
the buffer list) complain. If the buffer is not found
and the "cflag" is TRUE, create it. The "bflag" is
the settings for the flags in in buffer.
If bflag specifies a TEMP buffer, then a TEMP buffer can be selected.
