otherwise.
This restores more efficient dotdot caching in NFS filesystems which
was lost when vnodes stoppped being type stable.

It's quite strange that nobody reported this issue before. It turns out
functions like ttyname(), ptsname() and fdevname() don't work in
compat32. This means it't not even possible to run applications like
script(1) inside a 32-bit FreeBSD jail.
Fix this by converting 32-bit fiodgname_arg structures to their 64-bit
equivalent.

An earlier solution by peter had been comitted in r183528 and backed out
in r183566 due to problems with newvers.sh also called from other places
during world build. With the extra test this survived a make universe.
The work have been under testing and fixing since then, and it is mature enough
to be put into HEAD for further testing.
A lot have changed in this time, and here are the most important:
- Gvinum now uses one single workerthread instead of one thread for each
volume and each plex. The reason for this is that the previous scheme was
very complex, and was the cause of many of the bugs discovered in gvinum.
Instead, gvinum now uses one worker thread with an event queue, quite
similar to what used in gmirror.
- The rebuild/grow/initialize/parity check routines no longer runs in
separate threads, but are run as regular I/O requests with special flags.
This made it easier to support mounted growing and parity rebuild.
- Support for growing striped and raid5-plexes, meaning that one can extend the
volumes for these plex types in addition to the concat type. Also works while
the volume is mounted.
- Implementation of many of the missing commands from the old vinum:
attach/detach, start (was partially implemented), stop (was partially
implemented), concat, mirror, stripe, raid5 (shortcuts for creating volumes
with one plex of these organizations).
- The parity check and rebuild no longer goes between userland/kernel, meaning
that the gvinum command will not stay and wait forever for the rebuild to
finish. You can instead watch the status with the list command.
- Many problems with gvinum have been reported since 5.x, and some has been hard
to fix due to the complicated architecture. Hopefully, it should be more
stable and better handle edge cases that previously made gvinum crash.
- Failed drives no longer disappears entirely, but now leave behind a dummy
drive that makes sure the original state is not forgotten in case the system
is rebooted between drive failures/swaps.
- Update manpage to reflect new commands and extend it with some examples.

It seems that some revision of controller hang while accessing
the VPD. Because VPD access routine are unused, nuke it.
o Let TWSI reload EEPROM if VPD capability is detected. Reloading
EEPROM will also set ethernet address so age(4) now reads AGE_PAR0
and AGE_PAR1 register to get ethernet address. This removes a lot
of hack and enhance readability a lot.
o Double PHY reset timeout as it takes more time to take PHY out of
power-saving state.
o Explicitly check power-saving state by checking undocumented PHY
registers. If link is not up, poke undocumented registers to take
PHY out of power-saving state. This is the same way what Linux
does. On resume, make sure to wake up PHY.
o Don't rely on auto-clearing feature of master reset bit, just wait
1ms and check idle status of MAC.
o Add PCI device revision information in bootverbose mode.
This should fix occasional controller hang in device attach phase.

Toshiba PCETC ISA card, and even has the same board type code in the
card ID (0x14). So, for this card, call ed_probe_WD80x3_generic after
setting things up apropriately. This makes the card attach and kinda
work (I'm seeing panics in sbdrop). Since history has shown that the
WD80x3 probe routine is dangerous, only do it for this card. Also,
disable the memory range check to make sure it is an valid ISA memory.
I think that it is bogus, but I'm not 100% sure, for these cards.
I removed probing for the WD80x3 in 2005 when I added support for the
AX88x90 and DL100xx cards since none of my cards had ever matched it
and PAO3 removed it and none of the cards in their database died.
It is possible there are other quirks about this card too, since no
other open source OS supports it, or even claims to support it. But
it was a fun half hour hack...
