When we exposed the PFSYNCF_OK flag to userspace in 5f5bf88949 we
unintentionally caused defer mode to always be enabled.
The ioctl check only looked for nonzero, not for the PFSYNCF_DEFER flag.
Fix this check and ensure ifconfig sets the flag.

Add two underscore characters "__" to names of BIT_* and BITSET_*
macros to move them to the implementation name space and to prevent
a name space pollution due to BIT_* macros in 3rd party programs with
conflicting parameter signatures.
These prefixed macro names are used in kernel header files to define
macros in e.g. sched.h, sys/cpuset.h and sys/domainset.h.
If C programs are built with either -D_KERNEL (automatically passed
when building a kernel or kernel modules) or -D_WANT_FREENBSD_BITSET
(or this macros is defined in the source code before including the
bitset macros), then all macros are made visible with their previous
names, too. E.g., both __BIT_SET() and BIT_SET() are visible with
either of _KERNEL or _WANT_FREEBSD_BITSET defined.
The main reason for this change is that some 3rd party sources
including sched.h have been found to contain conflicting BIT_*
macros.
As a work-around, parts of shed.h have been made conditional and
depend on _WITH_CPU_SET_T being set when sched.h is included.
Ports that expect the full functionality provided by sched.h need
to be built with -D_WITH_CPU_SET_T. But this leads to conflicts if
BIT_* macros are defined in that program, too.
This patch set makes all of sched.h visible again without this
parameter being passed and without any name space pollution due
to BIT_* macros becoming visible when sched.h is included.
This patch set will be backported to the STABLE branches, but ports
will need to use -D_WITH_CPU_SET_T as long as there are supported
releases that do not contain these patches.

Default action for ldconfig is specified as -R AKA 'append', and for
no-args (without options changing default actions), ldconfig should
append empty list of directories to current list. But because the check
was done before options were parsed out, presence of any option turned
off default rescan.
As result, innocently-looked commands like `ldconfig -v' were interpreted
as setting directory hints list to one specified on the command line,
i.e. empty.

As far as we know, there is no FAT implementation that supported hard
links, and our msdosfs driver assumed one cluster chain is only
referenced by one directory entry and clears it out when the file is
deleted. On the other hand, the current code would proceed with
checkchain() when the directory entry's head cluster is a valid numbered
cluster without checking if it was a valid head node of a cluster chain.
So if the cluster do not being a chain (e.g. CLUST_FREE, CLUST_BAD),
or was already referenced by another directory entry, this would
trigger an assertion in check_chain() at a later time.
Fix this by giving the user an option to truncate the directory entry
when the head cluster is an invalid cluster, an visited head node,
or not a head node.

Geom utilities (geli(8), glabel(8), gmirror(8), gpart(8), gmirror(8),
gmountver(8), etc) all use the geom(8) utility as their back end
to process their commands and pass them into the kernel. Creating
a new utility requires no more than filling out a template describing
the commands and arguments that the utility supports. Consider the
specification for the very simple gmountver(8) utility:
struct g_command class_commands[] = {
{ "create", G_FLAG_VERBOSE | G_FLAG_LOADKLD, NULL,
{
G_OPT_SENTINEL
},
"[-v] prov ..."
},
{ "destroy", G_FLAG_VERBOSE, NULL,
{
{ 'f', "force", NULL, G_TYPE_BOOL },
G_OPT_SENTINEL
},
"[-fv] name"
},
G_CMD_SENTINEL
};
It has just two commands of its own: "create" and "destroy" along
with the four standard commands "list", "status", "load", and
"unload" provided by the base geom(8) utility. The base geom(8)
utility allows each command to use the G_FLAG_VERBOSE flag to specify
that a command should accept the -v flag and when the -v flag is
given the utility prints "Done." if the command completes successfully.
In the above example, both of the commands set the G_FLAG_VERBOSE,
so have the -v option available. In addition the "destroy" command
accepts the -f boolean flag to force the destruction.
If the "destroy" command wanted to also print out verbose information,
it would need to explicitly declare its intent by adding a line:
{ 'v', "verbose", NULL, G_TYPE_BOOL },
Before this change, the geom utility would silently ignore the above
line in the configuration file, so it was impossible for the utility
to know that the -v flag had been set on the command. With this
change a geom command can explicitly specify a -v option with a
line as given above and handle it as it would any other option. If
both a -v option and G_FLAG_VERBOSE are specified for a command
then both types of verbose information will be output when that
command is run with -v.

The last two drivers that required sppp are cp(4) and ce(4).
These devices are still produced and can be purchased
at Cronyx <http://cronyx.ru/hardware/wan.html>.
Since Roman Kurakin <rik@FreeBSD.org> has quit them, they no
longer support FreeBSD officially. Later they have dropped
support for Linux drivers to. As of mid-2020 they don't even
have a developer to maintain their Windows driver. However,
their support verbally told me that they could provide aid to
a FreeBSD developer with documentaion in case if there appears
a new customer for their devices.
These drivers have a feature to not use sppp(4) and create an
interface, but instead expose the device as netgraph(4) node.
Then, you can attach ng_ppp(4) with help of ports/net/mpd5 on
top of the node and get your synchronous PPP. Alternatively
you can attach ng_frame_relay(4) or ng_cisco(4) for HDLC.
Actually, last time I used cp(4) back in 2004, using netgraph(4)
instead of sppp(4) was already the right way to do.
Thus, remove the sppp(4) related part of the drivers and enable
by default the negraph(4) part. Further maintenance of these
drivers in the tree shouldn't be a big deal.
While doing that, remove some cruft and enable cp(4) compilation
on amd64. The ce(4) for some unknown reason marks its internal
DDK functions with __attribute__ fastcall, which most likely is
safe to remove, but without hardware I'm not going to do that, so
ce(4) remains i386-only.

ping uses a two-pass option parser. The first pass determines whether
ipv4 or ipv6 is desired, and the second parses the rest of the options.
But the first pass wrongly detects a '4' or '6' in an option's value as
a request to use ipv6 or ipv6 respectively, for example in an invocation
like "ping -c6 1.2.3.4".
Fix this confusion by including all options in the first round of
parsing, but ignoring those unrelated to ipv4/ipv6 selection.
