- arm64 UEFI support added in 11.0

The AUTHORS section included the folks responsible for the bulk of the
work to bring UEFI support to amd64, but missed those who did the
original work on ia64, the initial port to i386, the ports to arm64 and
arm, and have generally maintained and improved general UEFI support
since then.  It's unwieldly to include everyone and would quickly become
outdated again anyhow, so just remove the AUTHORS section.

b37f6c9805 Add libregex, connect it to the build
libregex is a regex(3) implementation intended to feature GNU extensions and
any other non-POSIX compliant extensions that are deemed worthy.

These extensions are separated out into a separate library for the sake of
not cluttering up libc further with them as well as not deteriorating the
speed (or lack thereof) of the libc implementation.

libregex is implemented as a build of the libc implementation with LIBREGEX
defined to distinguish this from a libc build. The reasons for
implementation like this are two-fold:

1.) Maintenance- This reduces the overhead induced by adding yet another
regex implementation to base.

2.) Ease of use- Flipping on GNU extensions will be as simple as linking
against libregex, and POSIX-compliant compilations can be guaranteed with a
REG_POSIX cflag that should be ignored by libc/regex and disables extensions
in libregex. It is also easier to keep REG_POSIX sane and POSIX pure when
implemented in this fashion.

Tests are added for future functionality, but left disconnected for the time
being while other testing is done.

a9f41deff6 Introduce aw_syscon(4) for earlier attachment
Attaching syscon_generic earlier than BUS_PASS_DEFAULT makes it more
difficult for specific syscon drivers to attach to the syscon node and to
get ordering right. Further discussion yielded the following set of
decisions:

- Move syscon_generic to BUS_PASS_DEFAULT
- If a platform needs a syscon with different attach order or probe
behavior, it should subclass syscon_generic and match on the SoC specific
compat string
- When we come across a need for a syscon that attaches earlier but only
specifies compatible = "syscon", we should create a syscon_exclusive driver
that provides generic access but probes earlier and only matches if "syscon"
is the only compatible. Such fdt nodes do exist in the wild right now, but
we don't really use them at the moment.

Additionally:

- Any syscon provider that has needs any more complex than a spinlock solely
for syscon access and a single memory resource should subclass syscon
directly rather than attempting to subclass syscon_generic or add complexity
to it. syscon_generic's attach/detach methods may be made public should the
need arise to subclass it with additional attach/detach behavior.

We introduce aw_syscon(4) that just subclasses syscon_generic but probes
earlier to meet our requirements for if_awg and implements #2 above for this
specific situation. It currently only matches a64/a83t/h3 since these are
the only platforms that really need it at the time being.

973c4efb9d Enable ld.lld as bootstrap linker by default on i386
Akin to r327783 for amd64.  lld has been usable for amd64 for quite some
time, but a couple of issues remained that affected i386.  These were
recently addressed upstream in lld and merged into FreeBSD (r326831,
r326879, r326897, r326957), so we can now use ld.lld on i386 as well.

Similarly to amd64 this change enables lld only as the bootstrap linker
(used to link the kernel and userland libraries and executables), while
GNU ld.bfd is still installed as /usr/bin/ld and used for ports builds.

The ports collection is essentially ready to use lld as the system
linker for amd64, but many ports still have trouble with lld on i386,
because lld defaults to -ztext, disallowing relocations against readonly
segments.  Thus switching the system linker (WITH_LLD_IS_LD) will happen
later on a per-arch basis.

c02fc9607a mallocarray(9): panic if the requested allocation would overflow
Additionally, move the overflow check logic out to WOULD_OVERFLOW() for
consumers to have a common means of testing for overflowing allocations.
WOULD_OVERFLOW() should be a secondary check -- on 64-bit platforms, just
because an allocation won't overflow size_t does not mean it is a sane size
to request.  Callers should be imposing reasonable allocation limits far,
far, below overflow.

93b7a1c153 Enable ld.lld as bootstrap linker by default on amd64
For some time we have been planning to migrate to LLVM's lld linker.
Having a man page was the last blocking issue for using ld.lld to link
the base system kernel + userland, now addressed by r327770.  Link the
kernel and userland libraries and binaries with ld.lld by default, for
additional test coverage.

This has been a long time in the making.  On 2013-04-13 I submitted an
upstream tracking issue in LLVM PR 23214: [META] Using LLD as FreeBSD's
system linker.  Since then 85 individual issues were identified, and
submitted as dependencies.  These have been addressed along with two
and a half years of other lld development and improvement.

I'd like to express deep gratitude to upstream lld developers Rui
Ueyama, Rafael Espindola, George Rimar and Davide Italiano.  They put in
substantial effort in addressing the issues we found affecting
FreeBSD/amd64.

To revert to using ld.bfd as the bootstrap linker, in /etc/src.conf set

    WITHOUT_LLD_BOOTSTRAP=yes

If you need to set this, please follow up with a PR or post to the
freebsd-toolchain mailing list explaining how default WITH_LLD_BOOTSTRAP
failed for your use case.

Note that GNU ld.bfd is still installed as /usr/bin/ld, and will still
be used for linking ports.  ld.lld can be installed as /usr/bin/ld by
setting in /etc/src.conf

    WITH_LLD_IS_LLD=yes

A followup commit will set WITH_LLD_IS_LD by default, possibly after
Clang/LLVM/lld 6.0 is merged to FreeBSD.

78f57a9cde Generalize the gzio API.
We currently use a set of subroutines in kern_gzio.c to perform
compression of user and kernel core dumps. In the interest of adding
support for other compression algorithms (zstd) in this role without
complicating the API consumers, add a simple compressor API which can be
used to select an algorithm.

Also change the (non-default) GZIO kernel option to not enable
compressed user cores by default. It's not clear that such a default
would be desirable with support for multiple algorithms implemented,
and it's inconsistent in that it isn't applied to kernel dumps.
