Rather than having a tool in the FreeBSD base system for obtaining
the FreeBSD ports tree, users are encouraged to `pkg install git`
and then `git clone https://git.FreeBSD.org/ports.git /usr/ports`.
The portsnap servers will continue operating until FreeBSD 13 reaches
its End-of-Life, and portsnap is available from the ports tree as
ports-mgmt/portsnap.

Latest meta.sys.mk follows sys.mk in including local.meta.sys.env.mk
and local.meta.sys.mk late, but we have things we need done early
so move them to local.meta.sys.env.mk
The whole point of the DIRDEPS_BUILD is to avoid tree walks
and basically build everything in a single pass.
We use the pseudo MACHINE "host" to represent the build host.
When the build host is not FreeBSD or is an older version of FreeBSD
it may need some help to build host-tools.
The directory tools/build does this - building libegacy.
local.sys.mk: create a pseudo option MK_host_egacy to indicate
if tools/build needs to be built for "host".
local.dirdeps.mk: set MK_host_egacy.host to ${MK_host_egacy}
all other DEP_MACHINES will get "no"
This allows a Makefile.depend.options in makefs etc to cause tools/build
to be built for host but only if necessary.
local.init.mk: use ISYSTEM as arg to -isystem so that it can be overridden.
The default remains ${STAGE_INCLUDEDIR}
src.init.mk: if MACHINE is host and we are not FreeBSD
set some MK_ flags the same as tools/build/mk/Makefile.boot.pre and
include src.init.${.MAKE.OS:tl}.mk if it exists.
For older versions of FreeBSD add libegacy when building PROGs for "host"
Also instead of -isystem${STAGE_INCLUDEDIR} we want
-I${STAGE_INCLUDEDIR} and -isystem/usr/include so we override ISYSTEM.
This means any headers we stage for "host" will take precedence over
system headers but #include_next will DTRT.
src.init.linux.mk: add
-I${SRCTOP}/tools/build/cross-build/include/linux
and generally deal with building host tools on Linux.
Eg. static linking does not work so set NO_SHARED= no
Override some HAVE_ flags.
src.sys.env.mk: on linux awk throws an warning about # in newvers.sh
just send stderr to /dev/null

Move the setting of TARGET_SPEC_VARS to local.sys.env.mk
so meta.sys.mk can do the processing, and include local.meta.sys.mk
later.
Move the setting of GENDIRDEPS_FILTER*_VARS from local.gendirdeps.mk
to local.meta.sys.mk so we can automatically set DEP_* at level 1+
to avoid syntax errors when DEP_* variables are used in conditionals
in Makefile.depend files.
Update gendirdeps.mk just to get the documentation about the above.
No functional change.
local.dirdeps.mk be more careful about adding to DIRDEPS to avoid
unnecessary overhead, and introducing cycles in the graph.

Several makefile depend on tools built for host.
At least when using DIRDEPS_BUILD we can build these for the
pseudo machine "host" to facilitate building on older host versions.
Ideally we would build these tools in their own directories to avoid
building more than needed.
For now, setting an appropriate default for BTOOLSPATH will suffice

if_bridge receives packets via a special interface, if_bridge_input,
rather than by if_input. Thus, netmap's usual hooking of ifnet routines
does not work as expected. Instead, modify bridge_input() to pass
packets directly to netmap when it is enabled. This applies to both
locally delivered packets and forwarded packets.
When a netmap application transmits a packet by writing it to the host
TX ring, the mbuf chain is passed to if_input, which ordinarily points
to ether_input(). However, when transmitting via if_bridge,
bridge_input() needs to see the packet again in order to decide whether
to deliver or forward. Thus, introduce a new protocol flag,
M_BRIDGE_INJECT, which 1) causes the packet to be passed to
bridge_input() again after Ethernet processing, and 2) avoids passing
the packet back to netmap. The source MAC address of the packet is used
to determine the original "receiving" interface.

Use the date of the last commit from gj@ (d276a4dfa6f5f3711808eff44ff20a92114b4d6e)
Note that for other developers the date is that when the commit bit was taken

Currently, sysctls which enable KDB in some way are flagged with
CTLFLAG_SECURE, meaning that you can't modify them if securelevel > 0.
This is so that KDB cannot be used to lower a running system's
securelevel, see commit 3d7618d8bf. However, the newer mac_ddb(4)
restricts DDB operations which could be abused to lower securelevel
while retaining some ability to gather useful debugging information.
To enable the use of KDB (specifically, DDB) on systems with a raised
securelevel, change the KDB sysctl policy: rather than relying on
CTLFLAG_SECURE, add a check of the current securelevel to kdb_trap().
If the securelevel is raised, only pass control to the backend if MAC
specifically grants access; otherwise simply check to see if mac_ddb
vetoes the request, as before.
Add a new secure sysctl, debug.kdb.enter_securelevel, to override this
behaviour. That is, the sysctl lets one enter a KDB backend even with a
raised securelevel, so long as it is set before the securelevel is
raised.
