setting a flag.  That way when we are called again we can be sure
to realloc() the right thing, regardless of the current value of
environ.  When the stashed value != environ (or when we are called
for the first time), copy the existing entries from environ and set
environ to the new value.  OK deraadt@, beck@, djm@

the dead directories and add new ones. Suggested by miod@.

Main features:
- MI hil drivers, allowing live plug/unplug of devices, and the keyboard
does not need to be at id 1 anymore.
- SGC bus support on 4xx models. SGC frame buffers are supported too, but
not as console, though you can use them as a regular glass terminal if
you run a getty on ttyC0. Currently not compiled-in, awaiting for an sti(4)
fix to be commited.
- HP-UX compatibility interfaces are removed. grfinfo and hilinfo are removed.
X11 support is currently broken by these changes; X.org X11R6 support will
be available very soon.
Tested on hyperion and 4 different flavours of catseye/topcat/kathmandu; other,
older frame buffers (davinci, gatorbox and renaissance) could not been tested
but should work; please report any regression.

use it in a vararg function call that needs the type info.
