7e49246c32 kern_environment: Give the static environment a chance to disable MD env
This variable has been given the name "loader_env.disabled" as it's the
primary way most people will have an MD environment. This restores the
previously-default behavior of ignoring the loader(8) environment, which may
be useful for vendor distributions or other scenarios where inheriting the
loader environment may be considered a security issue or potentially
breaking of a more locked-down environment.

As the change to config(5) indicates, disabling the loader environment
should not be a choice made lightly since it may provide ACPI hints and
other useful things that the system can rely on to boot.

An UPDATING entry has been added to mention an upgrade path for those that
may have relied on the previous behavior.

6615ed4c61 Make struct xinpcb and friends word-size independent.
Replace size_t members with ksize_t (uint64_t) and pointer members
(never used as pointers in userspace, but instead as unique
idenitifiers) with kvaddr_t (uint64_t). This makes the structs
identical between 32-bit and 64-bit ABIs.

On 64-bit bit systems, the ABI is maintained. On 32-bit systems,
this is an ABI breaking change. The ABI of most of these structs
was previously broken in r315662.  This also imposes a small API
change on userspace consumers who must handle kernel pointers
becoming virtual addresses.

6627c6e55a core(5): overwrite the oldest core dump
The '%I' format in the kern.corefile sysctl limits the number of
core files that a process can generate to the number stored in the
debug.ncores sysctl. The '%I' format is replaced by the single digit
index. Previously, if all indexes were taken the kernel would overwrite
only a core file with the highest index in a filename.
Currently the system will create a new core file if there is a free
index or if all slots are taken it will overwrite the oldest one.

messages, go ahead and also change the syslog(3) libc function to

dfdfdc183e Add note to UPDATING about UEFI changes requiring loader(8) update
These problems have only been observed with boards using U-Boot (e.g. ARM)
where virtual addresses are already set in the memory map by the firmware
and the firmware is expecting a call to SetVirtualAddressMap to be made.
I refrain from mentioning this in the note because this could also be the
case on some not-yet-tested firmware on amd64 and it's not a bad
recommendation for the general case.

974e9d9ccc Add Lua as a scripting langauge to /boot/loader
liblua glues the lua run time into the boot loader. It implements all
the runtime routines that lua expects. In addition, it has a few
standard 'C' headers that nueter various aspects of the LUA build that
are too specific to lua to be in libsa. Many refinements from the
original code to improve implementation and the number of included lua
libraries. Use int64_t for lua_Number. Have "/boot/lua" be the default
module path. Numerous cleanups from the original GSoC project,
including hacking libsa to allow lua to be built with only one change
outside luaconf.h.

Add the final bit of lua glue to bring in liblua and plug into the
multiple interpreter framework, previously committed.

Add LOADER_LUA option, currently off by default.

Presently, this is an experimental option. One must opt-in to using
this by defining WITH_LOADER_LUA and WITHOUT_FORTH. It's been
lightly tested, so keep a backup copy of your old loader handy.
The menu code, coming in the next commit, hasn't been exhaustively
tested. A LUA boot loader is 60k larger than a FORTH one, which is
80k larger than a no-interpreter one. Subtle changes in size
may tip things past some subtle limit (the binary is ~430k now
when built with LUA). A future version may offer coexistance.

Bump FreeBSD version to 1200058 to mark the milestone.

a74104797b Disabled the use of flowid for lagg by default
Disabled the use of RSS hash from the network card aka flowid for
lagg(4) interfaces by default as it's currently incompatible with
the lacp and loadbalance protocols.

The incompatibility is due to the fact that the flowid isn't know
for the first packet of a new outbound stream which can result in
the hash calculation method changing and hence a stream being
incorrectly split across multiple interfaces during normal
operation.

This can be re-enabled by setting the following in loader.conf:
net.link.lagg.default_use_flowid="1"
