when the "resize" wctl was used on a hidden window, the window
was put back on the screen, however, it was not removed from
the hidden[] array so trying to hide the window again failed
because whide() assumed it was already hidden.
the fix is to not unhide the window, but preserve the hidden
state, so windows can programmatically be reshaped and moved,
but will remain hidden unless explicitely unhidden.
we can improve performance alot by using webfs which
does http keep alives for us, so connection setup
overhead is eleminated.
fix 9p flushes and double frees.
in backwards mode, the roles of the aan filters need to be
reversed. add "-n address" option to import to override the
announce address for the aan server part (default tcp!*!0).
old iostats failed to work when builidng the kernel due to old bugs
that where already fixed in exportfs. instead of backporting the fixes,
reimplement iostats as a filter that sits between exportfs and the
process mount. from users perspective, theres no difference.
the result is much smaller and can handle everything that exportfs
can like /srv.
instead of naming devices by ther dynamically assigned device address,
we hash device uniqueue fields from the device descriptor and produce
a 5 digit hex string that will identify the device across machines.
when there is a collision (less than 1% chance with 100 devices),
usbd will append the device address to the name to make it uniqueue
for this machine.
the hname is passed to drivers in the devid argument, which now has
the form addr:hname, where the colon and hname can be omited (for backwards
compatibility).
when the new behaviour isnt desired, nousbhname= environment variable
can be defined giving the old behaviour.
mouse acceleration can be done by software in the kernels
devmouse device like:
echo hwaccel off >/dev/mousectl
echo accelerated 5 >/dev/mousectl
it is hard to pass nusb/kb parameters anyway as it is started
from nusbrc in bootfs.paq, so i remove the option.
