First step inn removing config_scan() and the hacks that gave devices
...
on indirect-config busses a (permanent) softc that they could share
between 'match' and 'attach' routines:
Define __BROKEN_INDIRECT_CONFIG so that old autoconfiguration
interfaces are used, until drivers are converted to use the new
interfaces (actually, converted back to use the _older_ interfaces)
which prohibit indirect configuration devices from receiving a softc
in their match routine that they can share with their attach routine.

ffs bootblock install can be simplified since installboot(8) handles that now.

installboot(8) now handles required a.out header munging.
...
Also, the munging is extended by inserting an instruction that branches
past the header, so the same boot image can be used on all supported
sun platforms.

Allow larger text (64MB) and data (256MB) segments.

On sun4/sun4c with a virtual address hole (starting at 512MB), this seems
like a reasonable compromise: about 196MB left for shared libs and sysv-style
shared memory segments.
On the sun4m the limits can easily be made larger: consider turning
MAXTSIZ and MAXDSIZ into tunable variables..

New-style crash dump format requires a slighty different interpretation of
...
the variable `dumpsize' (used by savecore(8)) and that the CPU specific data
gets dumped first.
Also, squash a typo that prevented the crash dump to be shifted towards the
end of the swap partition. In fact, the entire dumpconf() routine has been
redone, mostly by pasting large chunks from the alpha port.
