Turn the sigio sx into a mutex.
Sigio lock is really only needed to protect interrupts from dereferencing
the sigio pointer in an object when the sigio itself is being destroyed.
In order to do this in the most unintrusive manner change pgsigio's
sigio * argument into a **, that way we can lock internally to the
function.
we don't collect any stats in it, we mii_tick() in it! This fix the bug
when autonegotiating fullduplex modes.
Also, pause activity before setting TXCON in epic_miibus_statchg(). Though
i've never seen problmes from not doing that, the documentation says we
need to do it.

well as is, so - just fetch current status upon MII_TICK.
Also do IFM_INST verification at the top of *_service() then doing it
separately for every case in switch.
acphy: do not read MII_ACPHY_DIAG twice, there is nothing latching.
qsphy: always fetch actual link status from MII_QSPHY_PCTL.

fatal if the declaration of strdup() isn't in scope. The upper 32 bits
of the pointer are lost since it defaults to returning "int". Fix some
warnings while here, including trying to make gcc-3.1 happy.
more on how ipfw(8) deals with tiny fragments. While we're at it, add
a quick log message to even let people know we dropped a packet. (Note
that the second FINE POINT is somewhat redundant given the first, but
since the code is there, leave the docs for it.)

This is an absolute (kelvin) temperature. I expect that in the original
source it was typeset as $\sim 300~{\rm K}$ or similar, meaning
"approximately 300 K". Changing it to a minus sign in the fortunes file
was clearly an error, as absolute temperatures are by definition positive.
Also add the ability to use Bzip'ed distributions -- but this is exclusive
of being able to use Gzip'ed distributions.

loading breakage'). The patch fixes serious issues with the VFS
operations vector array which results in a crash when a filesystem module
adding a new VOP is loaded into the kernel. Basically what was happening
before was that the old operations vector was being freed and a new one
allocated. The original MALLOC code tended to reuse the same address
for the case and so the bug did not rear its ugly head until the new memory
subsystem was emplaced.
This patch replaces the temporary workaround Dave O'Brien comitted in 1.58.
The patch is clean enough that I intend to MFC it to stable at some point.
