hw.vga.textmode is directing VT VGA backend to use text mode.
The default screen mode for BIOS loader is text, and default
screen mode for VT VGA backend is graphics (unless we are running on
hypervisor or hw.vga.textmode is set to 1). Using hw.vga.textmode
for loader does remove possibility to have graphical mode VT VGA with
text mode loader.
screen.textmode can have possible values "0" to disable text mode,
and "1" to set text mode.
Rework the arguments handling around using getopt_long:
* add long option support
* add -4 and -6 support to enforce ipv4 or ipv6

Instead of trying to set reasonable register values, save significant
register values, then prepare for font upload and then restore
registers from saved data.
This seems to fix text mode for most cases where text mode breakage
was reported.
The routine can be used when the caller does not expect to ever have to
wait for anything. Checking later with seqc_consistent retains all the
guarantees.
Now that we've split up the datastructures used by the kernel and
userspace there's essentually no more overlap between the pf_ruleset.c
code used by userspace and kernelspace.
Copy the userspace bits to the pfctl directory and stop using the kernel
file.

Improve caching behaviour by using counter_u64 rather than variables
shared between cores.
The result of converting all counters to counter(9) (i.e. this full
patch series) is a significant improvement in throughput. As tested by
olivier@, on Intel Xeon E5-2697Av4 (16Cores, 32 threads) hardware with
Mellanox ConnectX-4 MCX416A-CCAT (100GBase-SR4) nics we see:

Factor out allocating and freeing pfi_kkif structures. This will be
useful when we change the counters to be counter_u64, so we don't have
to deal with that complexity in the multiple locations where we allocate
pfi_kkif structures.
No functional change.

The u_* counters are used only to communicate with userspace, as
userspace cannot use counter_u64. As pf_krule is not passed to userspace
these fields are now obsolete.

Only keep the widechar version of ncurses as libncursesw.so.9
Keep the old name to avoid breaking the ABI compatibility (the non
widechar version libncurses.so.9 is not binary compatible with
libncursesw.so.9) since all ports and base are already only linking
against the widechar version we can simply remove libncurses.so.9
Since the .9 version only lived in the dev branch and never ended in a
release, it is simply removed and not added to any binary compat
package.
Add symlinks to keep build time compatibility for anyone linking against
-lncurses
In libcasper, the first argument to the function is a structure that
represents a connection to Casper. On systems without Casper, macros
are used to interpose the Casper functions to standard libc ones.
This may cause errors/warnings that the variable is not used.
With the inline function, there is no such problem.
We increment the overflow count when receiving an overflow interrupt
with special care to check if it happens while reading the event counter.
