If we are not transfering any data, use a non S/G ccb type that doesn't
return residual information. It seems that some firmware revisions dislike
S/G ccbs with 0 length S/G lists.
Correct bt_cmd() so that we always honor command status that was latched
by our interrupt routine while polling for completion..
programs using glibc expect edx to be preserved accross syscalls.
As a result, linux programs running in emulation mode can
have whatever value may be represented by edx clobbered.

is more robust and common code can be used for both the target and iniator
roles. The mechanism for tracking negotiation state has also been simplified.
Add support for sync/wide negotiation in target mode and fix many of
the target mode bugs running at higher speeds uncovered. Make a first
stab at getting all of the bus skew delays correct. Sync+Wide dataout
transfers still cause problems, but this may be an initiator problem.
Ensure that we exit BITBUCKET mode if the controller is restarted.
Add support for target mode only firmware downloads. This has been
tested on the aic7880, but should mean that we can perform target mode
on any aic7xxx controller. Mixed mode (initiator and target roles in
the same firmware load) is currently only supported on the aic7890, but
with optimization, may fit on chips with less instruction space.
Allow sync transfers if the controller supports it. Wide will follow
as soon as I get the kinks worked out of wide target transfers in the
aic7xxx driver (currently the only target mode driver in the tree).
to specify that it does not provide initiator services (PIM_NOINITIATOR)
and that the initial bus reset for device probing should be avoided
(PIM_NOBUSRESET).
Modify the XPT layer to honor these flags.
0. This makes it difficult to do efficient manipulation of the
struct pollfd since you can't leave a slot empty.

1) Removed 'emulation' of bitmaps in printfs, FreeBSD seems to have caught
up on that one
2) Fixed a few bugs in the timeout/timo timeout variables
3) First attempt at fixing a bug mentioned by Kazu: uhci_run is not able
start/stop his USB host on his motherboard.
that the generated files are generated before any of the object files.
Also minor cleanup of dependencies in conf/files that I bogusly added
before.
This should fix the requirement that make depend be done starting from
a clean config directory. If you don't have a clean directory, make
depend is still required if you want the proper .o's to be recompiled.
