shuffler: correctly handle one-to-many relationships

shuffler library handle those cases correctly, and remove a
special-purpose hack in sdi.c.
This is based on the observation that all one-to-many relationships
can be treated as a one-to-one shuffle followed by
destination-to-destination copies; i.e. one copy is (arbitrarily)
assigned the "master copy" status, and all aliases are then copied
from the master copy when the master copy is already in its final
place. All other copies can then be simply ignored for the duration
of the shuffle, just as zero-memory is.

shuffle_rm: set up SS:ESP and segs as quickly as possible
For extra paranoia's sake, set up SS:ESP immediately after the
real-mode switch, and then set all the segment registers.

a20: advance A20Test by a large, prime number
Rather than simply incrementing A20Test, advance it by a large prime
number every time. The reason is to minimize false aliasing as
quickly as possible.

a20: remove DO_WBINVD configurable
We haven't enabled DO_WBINVD for a very long time. A20 is implemented
on the inside of the L1 cache for 486+ (and 386 didn't have WBINVD),
so an I/O delay is the only thing we can rely on anyway.

a20: try to avoid io_delay if A20 is already enabled
We have at least the possibility to avoid io_delay if A20 is already
enabled. Thus, give it a try. Furthermore, when calling enable_a20,
always try the zero-work case first, since we may have been enabled by
a previous call. This should improve performance of the rm/pm
ping-pong.
