- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

Update ipfilter 4.1.28 --> 5.1.2.

Link ipfilter(4) and ipfilter(5) to the build to stop the wrong man page
displaying for 'man 4 ipfilter'.

Use both NO_WFORMAT and NO_WARRAY_BOUNDS for sbin/ipf, it would be too
disruptive to actually fix all the warnings, and the code hasn't been
maintained for several years.

Always assign WARNS using ?=

- fix some nearby style bugs
- include Makefile.inc where it makes sense and reduces duplication

Approved by: ed (co-mentor)

Switch the default WARNS level for sbin/ to 6.

This makefile builds contrib code, so I won't try to fix all the
casts from pointer to int here.

Exclude inet_addr.c from the build.
It only provides inet_aton(), which is already provided by the libc. This
causes multiple symbol definitions when linking statically.

Merge IPFilter 4.1.23 back to HEAD
See src/contrib/ipfilter/HISTORY for details of changes since 4.1.13

Fix the manual build.

Regularly scheduled patch to unbreak regularly scheduled post-ipfilter
buildworld breakage.

Exclude loglevel.c from the build. It does not appear to be used by
anything in the tree and buildworld succeeds just fine without it.

Adapt to ipf 4.1.13

Add missing library dependencies.

Add printproto.c to libipf

Fix the contents of the underneath .depend files and "make checkdpadd".

Enable building /sbin/ipf (but not the rescue version) with the ability to
parse bpf strings for filter rules in ipf.conf

Patches from Ruslam Ermilov to remove NetBSD bits from Makefiles and cleanup
build problems with rescue.

Move my maintainership of parts of ipfilter back to Darren Reed

* add extra -I path to get the "matching" header files.

Default to WARNS=2.
Binary builds that cannot handle this must explicitly set WARNS=0.

Pick up the correct headers from sys/contrib/ipfilter/netinet.

Backout previous change (removal of -I${.CURDIR}/../../sys/netinet).
This is needed to pick up the right headers. Wrong headers from
src/contrib/ipfilter are used otherwise.

The right fix would be to fix contrib/ipfilter C sources to pick up
headers from <sys/netinet>.

Removed -I${.CURDIR}/.../sys from CFLAGS.

Build with -DUSE_INET6 so that we can actually use the IPv6 support in
