change structure member names to be in line with what various ECOFF

Browse Source 
documentation I have calls them.  This makes it easier to simulate
a 'normal' ECOFF environment.  Add an 'ecoff_exechdr' structure which
includes the filehdr and aouthdr.  (That idea taken from the Mach header
formerly used by the Alpha boot blocks.) Simpify the macros used to get
various bits of information, and make most of them take pointers to
the exechdr structure rather than individual pointers to the filehdr
and/or aouthdr.
