gcc emits the deprecated sparc v8 instructions that use this register
when optimizing for UltraSparc machines because they are apparetly
faster then their v9 counterpars there.

- Minor space adjustment in cases where we have "( ", " )", if(), return(),
while(), for(), etc.
- Add /* SYMBOL */ after a few #endifs.

machdep.guessed_bootdev, and add code to sysctl to parse its value
and give a (not necessarily correct) name to the device we booted
from (the main motivation for this code is to use the info in the
PicoBSD boot scripts, and the impact on the kernel is minimal).
NOTE: the information available in bootdev is not always reliable,
so you should not trust it too much. The parsing code is the same
as in boot2.c, and cannot cover all cases -- as it is, it seems to
work fine with floppies and IDE disks recognised by the BIOS. It
_should_ work as well with SCSI disks recognised by the BIOS.
Booting from a CDROM in floppy emulation will return /dev/fd0 (because
this is what the BIOS tells us).
Booting off the network (e.g. with etherboot) leaves bootdev unset so
the value will be printed as "invalid (0xffffffff)".
Finally, this feature might go away at some point, hopefully when we
have a more reliable way to get the same information.

see how often these days style cleanus break doesn't broken things. Perhaps
people should recall good old principle: "don't fix it if it isn't broken".

-#if defined(__FreeBSD__) && __FreeBSD_version__ >= 500023
+#if defined(__FreeBSD__) && __FreeBSD_version >= 500023
is a genuine bug -- __FreeBSD_version__ does not exist.
The other one:
-#if (__FreeBSD__ < 5)
+#if (__FreeBSD_version < 500000)
pops out when you cross-compile the code:
__FreeBSD__ is a compiler predefine,
__FreeBSD_version is defined in <sys/param.h> .
Given that in this case (and all others in sys/dev/usb and sys/i4b)
the goal is to adapt to a different kernel interface, and not to
a compiler feature, I believe the correct form is the second one
(in the best case the two are synonyms so the change does not break
anything anyways).
