55c9a224e2 release.7: update for current context
It's no longer unusual to be able to build a release with a single
command, so drop "actually" that hints at a surprise.  Also just use
"network install directory" instead of referencing FTP; it's more
likely to be HTTP now.

5c4f8d801c lib: add libnetmap
This changeset introduces the new libnetmap library for writing
netmap applications.
Before libnetmap, applications could either use the kernel API
directly (e.g. NIOCREGIF/NIOCCTRL) or the simple header-only-library
netmap_user.h (e.g. nm_open(), nm_close(), nm_mmap() etc.)

The new library offers more functionalities than netmap_user.h:
  - Support for complex netmap options, such as external memory
    allocators or per-buffer offsets. This opens the way to future
    extensions.
  - More flexibility in the netmap port bind options, such as
    non-numeric names for pipes, or the ability to specify the netmap
    allocator that must be used for a given port.
  - Automatic tracking of the netmap memory regions in use across the
    open ports.

At the moment there is no man page, but the libnetmap.h header file
has in-depth documentation.

489377c0a4 Avoid recomputing COMPILER_/LINKER_ variables when set explicitly
I noticed that when we build libraries for a different ABI (in CheriBSD) we
were calling ${XCC}/${LD} --version for every directory. It turns out that
this was caused by bsd.compat.mk explicitly setting (X_)COMPILER variables
for that build stage and this stops the _can_export logic from working.
To fix this, we change the check to only set _can_export=no if the variable
is set and it is set to a different value than the cached value.
This noticeably speeds up the tree walk while building compat libraries.
During an upstream amd64 buildworld this also removes 8 --version calls.

2b6ee34cf6 Pass -fuse-ld=/path/to/ld if ${LD} != "ld"
This is needed so that setting LD/XLD is not ignored when linking with $CC
instead of directly using $LD. Currently only clang accepts an absolute
path for -fuse-ld= (Clang 12+ will add a new --ld-path flag), so we now
warn when building with GCC and $LD != "ld" since that might result in the
wrong linker being used.

We have been setting XLD=/path/to/cheri/ld.lld in CheriBSD for a long time and
used a similar version of this patch to avoid linking with /usr/bin/ld.
This change is also required when building FreeBSD on an Ubuntu with Clang:
In that case we set XCC=/usr/lib/llvm-10/bin/clang and since
/usr/lib/llvm-10/bin/ does not contain a "ld" binary the build fails with
`clang: error: unable to execute command: Executable "ld" doesn't exist!`
unless we pass -fuse-ld=/usr/lib/llvm-10/bin/ld.lld.

This change passes -fuse-ld instead of copying ${XLD} to WOLRDTMP/bin/ld
since then we would have to ensure that this file does not exist while
building the bootstrap tools. The cross-linker might not be compatible with
the host linker (e.g. when building on macos: host-linker= Mach-O /usr/bin/ld,
cross-linker=LLVM ld.lld).

9e5787d228 Merge OpenZFS support in to HEAD.
The primary benefit is maintaining a completely shared
code base with the community allowing FreeBSD to receive
new features sooner and with less effort.

I would advise against doing 'zpool upgrade'
or creating indispensable pools using new
features until this change has had a month+
to soak.

Work on merging FreeBSD support in to what was
at the time "ZFS on Linux" began in August 2018.
I first publicly proposed transitioning FreeBSD
to (new) OpenZFS on December 18th, 2018. FreeBSD
support in OpenZFS was finally completed in December
2019. A CFT for downstreaming OpenZFS support in
to FreeBSD was first issued on July 8th. All issues
that were reported have been addressed or, for
a couple of less critical matters there are
pull requests in progress with OpenZFS. iXsystems
has tested and dogfooded extensively internally.
The TrueNAS 12 release is based on OpenZFS with
some additional features that have not yet made
it upstream.

Improvements include:
  project quotas, encrypted datasets,
  allocation classes, vectorized raidz,
  vectorized checksums, various command line
  improvements, zstd compression.

Thanks to those who have helped along the way:
Ryan Moeller, Allan Jude, Zack Welch, and many
others.

8a0edc914f Add prng(9) API
Add prng(9) as a replacement for random(9) in the kernel.

There are two major differences from random(9) and random(3):

- General prng(9) APIs (prng32(9), etc) do not guarantee an
  implementation or particular sequence; they should not be used for
  repeatable simulations.

- However, specific named API families are also exposed (for now: PCG),
  and those are expected to be repeatable (when so-guaranteed by the named
  algorithm).

Some minor differences from random(3) and earlier random(9):

- PRNG state for the general prng(9) APIs is per-CPU; this eliminates
  contention on PRNG state in SMP workloads.  Each PCPU generator in an
  SMP system produces a unique sequence.

- Better statistical properties than the Park-Miller ("minstd") PRNG
  (longer period, uniform distribution in all bits, passes
  BigCrush/PractRand analysis).

- Faster than Park-Miller ("minstd") PRNG -- no division is required to
  step PCG-family PRNGs.

For now, random(9) becomes a thin shim around prng32().  Eventually I
would like to mechanically switch consumers over to the explicit API.
