Backing out last change; no immediate plans to make the whole block-device
...
layer asynchronous, so keeping the sync/async boundary within aoedev.c
seems cleanest for now.

Until we have a functioning UDP stack and PXE API again, there's not much
...
point trying to use the old boot sequence. Replaced with a call to the
AoE demo code, so that people can at least build and try something useful.

elegant, but it works).

ATA devices are now asynchronous. The ATA layer itself now performs the
...
async_wait(), though we may wish to move this higher up the stack, and
consider making the block device model asynchronous. (There is only a
marginal cost for synchronous devices, since they can simply call
async_done() before returning; async_wait() will work seamlessly in this
situation).

Added generic asynchronous operations code.
...
Removed data_in_len and data_out_len from ata_command structure; the
lengths are implied by the sector count and the presence of the data_in
or data_out pointers.
Changed AoE code to use subcommands by default, and made aoe_issue()
nonblocking (with completion via async_wait()).

Added first sketch of a generic retry timer mechanism. The idea is to use
...
these timer objects in AoE and UDP protocols (where there is no underlying
retransmission mechanism) without requiring each protocol to implement its
own individual retry logic. Eventually, we should be able to use the same
timer code for TCP retransmissions as well.

Initial AoE implementation. Limitations are:
...
Cannot yet handle reads of more than two sectors
No retransmission
No way to find out a target's MAC address (this proof of concept uses
broadcasts)
These limitations shall not last long! :)

Change semantics; relocate() now just finds a suitable location; it

the copy in flat real mode.
