Enable polling to be configured into kernels on non i386 platforms. Note that
poll_in_trap is only implemented on i386. I've tested this on alpha.

Approved by: luigi

Move the PCI_ENABLE_IO_MODES option from conf/options.i386 to
conf/options.

Device Polling code for -current.

Non-SMP, i386-only, no polling in the idle loop at the moment.

To use this code you must compile a kernel with

options DEVICE_POLLING

and at runtime enable polling with

sysctl kern.polling.enable=1

The percentage of CPU reserved to userland can be set with

sysctl kern.polling.user_frac=NN (default is 50)

while the remainder is used by polling device drivers and netisr's.
These are the only two variables that you should need to touch. There
are a few more parameters in kern.polling but the default values
are adequate for all purposes. See the code in kern_poll.c for
more details on them.

Polling in the idle loop will be implemented shortly by introducing
a kernel thread which does the job. Until then, the amount of CPU
dedicated to polling will never exceed (100-user_frac).
The equivalent (actually, better) code for -stable is at

http://info.iet.unipi.it/~luigi/polling/

and also supports polling in the idle loop.

NOTE to Alpha developers:
There is really nothing in this code that is i386-specific.
If you move the 2 lines supporting the new option from
sys/conf/{files,options}.i386 to sys/conf/{files,options} I am
pretty sure that this should work on the Alpha as well, just that
I do not have a suitable test box to try it. If someone feels like
trying it, I would appreciate it.

NOTE to other developers:
sure some things could be done better, and as always I am open to
constructive criticism, which a few of you have already given and
I greatly appreciated.
However, before proposing radical architectural changes, please
take some time to possibly try out this code, or at the very least
read the comments in kern_poll.c, especially re. the reason why I
am using a soft netisr and cannot (I believe) replace it with a
simple timeout.

Introduce new syscons(4) kernel options:
- SC_CUT_SPACES2TABS - when copying text into the cut buffer convert leading
spaces into the tabs;
- SC_CUT_SEPCHARS="XYZ" - treat supplied characters as possible words
separators when the driver searches for words boundaries when doing cut
operation.

Also unify cut code a bit to decrease amount of duplicated code. This fixes
line cut mode, so that it is no longer pads line with useless spaces.

Optionize UPAGES for the i386. As part of this I split some of the low
level implementation stuff out of machine/globaldata.h to avoid exposing
UPAGES to lots more places. The end result is that we can double
the kernel stack size with 'options UPAGES=4' etc.

This is mainly being done for the benefit of a MFC to RELENG_4 at some
point. -current doesn't really need this so much since each interrupt
runs on its own kstack.
