f9f8ac94cd stand: Flip the default interpreter to Lua
After years in the making, lualoader is ready to make its debut. Both
flavors of loader are still built by default, and may be installed as
/boot/loader or /boot/loader.efi as appropriate either by manually creating
hard links or using LOADER_DEFAULT_INTERP as documented in build(7).

e10ba80063 ls(1): Add --color=when
--color may be set to one of: 'auto', 'always', and 'never'.

'auto' is the default behavior- output colors only if -G or COLORTERM are
set, and only if stdout is a tty.

'always' is a new behavior- output colors always. termcap(5) will be
consulted unless TERM is unset or not a recognized terminal, in which case
ls(1) will fall back to explicitly outputting ANSI escape sequences.

'never' to turn off any environment variable and -G usage.

b43c6042c3 Finalize the boot manager protocol support for next-stage boot
loading.

If we are booting in a conforming UEFI Boot Manager Environment, then
use the BootCurrent variable to find the BootXXXX we're using. Once we
find that, then if it contains more than one EFI_DEVICE_PATH in its
what to boot section, try to use the last one as the kernel to
load. This will also set the default root partition as well. If
there's only one path, or if there's an error along the way, assume
that nothing specific was specified and revert to the old
algorithm. If something was specified, but not found, then fail the
boot. Otherwise you that, specific thing. On FreeBSD, this can be set
using efibootmgr -l <loader> -k <kernel>. We try a few variations of
kernel to cope with the fact that UEFI comes from a DOS world where
paths might be upper case and/or contain back-slashes.

Note: In an ideal world, we'd work out where we are in chain loading
by looking at the passed-in image handle and doing name
matching. However, that's unreliable since at least boot1.efi booted
images don't have that, hence the assumption that loader.efi needs to
load the last thing on the list, if possible.

The reason we fail for something specific is so that we can fully
participate in the UEFI Boot Manager Protocol and fail over to the
next item in the list of BootOrder choices when something goes wrong
at this stage.

This implements was was talked about in freebsd-arch@ last year
https://docs.freebsd.org/cgi/getmsg.cgi?fetch=3576+0+archive/2017/freebsd-arch/20171022.freebsd-arch
and documented in full (after changed resulting from the discussion) in
https://docs.google.com/document/d/1aK9IqF-60JPEbUeSAUAkYjF2W_8EnmczFs6RqCT90Jg/edit#
although one or two minor details may have been modified in this
implementation to make it work, and the ZFS MEDIA PATH extension isn't
implemented. This does not yet move things to ESP:\efi\freebsd\loader.efi.

44314c3509 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.

f38b68ae8a 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.

0dea6e3c98 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.
