e290182bcf Remove 'make update'.
In the CVS days this used be a wrapper around either CVS or CVSup and
used to support updating src, doc, and ports checkouts.  With the move
to subversion this only supported updating src and was itself a
wrapper around 'svn update'.  With Git, users are probably better off
using appropriate Git commands directly to update without needing an
explicit make target as a wrapper.

123ae3045d build: remove LIBPTHREAD/LIBTHR build options
WITHOUT_LIBTHR has been broken for a little over five years now, since the
xz 5.2.0 update introduced a hard liblzma dependency on libthr, and building
a useful system without threading support is becoming increasingly more
difficult.

Additionally, in the five plus years that it's been broken more reverse
dependencies have cropped up in libzstd, libsqlite3, and libcrypto (among
others) that make it more and more difficult to reconcile the effort needed
to fix these options.

Remove the broken options.

26490d9b74 pkgbase: allow update-packages for first-run of packaging
If ${REPODIR}/${PKG_ABI} does not exist when we begin real-update-packages,
skip the comparison with the non-existent previous repository and just
finish the repo off. This allows external scripts to just assume they can
run `update-packages` rather than figuring out if they'd previously run
`packages` for this Version/Arch combo.

PKG_VERSION_FROM_DIR was added so that we could perhaps detect the three
distinct cases:

1.) If the repo has not yet been created, PKG_VERSION_FROM_DIR will be
  empty.
2.) If the repo is in some intermediate state between created and fully
  initialized, PKG_VERSION_FROM_DIR may point to the ABI directory.
3.) If the repo is fully initialized, then PKG_VERSION_FROM_DIR points to
  the latest build to compare to.

Option #2 is explicitly unhandled at the moment, but this is no different
than it was before.

613fe5321f pkgbase: differentiate package versions for ALPHA/BETA/PRERELEASE/RC phases
The current postfix conversions are:

  CURRENT / STABLE / PRERELEASE, 12.x-CURRENT becomes 12.snapYYYYMMDDhhmmss
  ALPHAx -> .ax, so 11.3-ALPHA1 becomes 11.3.a1.YYYYMMDDhhmmss
  BETAx -> .bx, so 12.1-BETA2 becomes 12.1.b2.YYYYMMDDhhmmss
  RCx -> .rcx, so 13.0-RC3 becomes 13.0.rc3.YYYYMMDDhhmmss
  RELEASE -> (nothing), so 12.1-RELEASE becomes 12.1
  RELEASE-pX -> pX, so 12.1-RELEASE-p1 becomes 12.1p1

Note that for development branches we will start to drop the minor version
component entirely, which more closely matches how these branches are
physically named (stable/NN).

snap is a new prefix that was added to pkg in [0], which is simply a more
verbose version of the current ".s" used.

As noted, build timestamps are also added to ALPHA/BETA/RC versions.  This
is largely irrelevant for re@ snapshots because they will only produce one
set of snapshots for each alpha/beta/rc, but external folks may produce
multiple in that timeframe -- at least for alpha.  For them, it is
imperative that the builds have a differentiating characteristic like this
rather than multiple builds across multiple revisions being versioned
identically.

03cab14ea3 Revert "pkgbase: differentiate package versions for ALPHA/BETA/PRERELEASE/RC phases"
This reverts commit aef769614f.

While the package names are a bit prettier this confuse pkg about upgrading :
$ pkg version -t 13.0.s2021011313063 13.0.a1
>
$ pkg version -t 13.0.s2021011313063 13.0_ALPHA1

Note that the current scheme isn't good when bumping from ALPHA to BETA or
even BETA to RC:
$ pkg version -t 13.0_ALPHA1 13.0_BETA1
=
$ pkg version -t 13.0_BETA1 13.0_RC1

94ffff68c8 Stop passing MK_WARNS=no for bootstrap tools
I got annoyed by the number of warnings that the CheriBSD build was
emitting. It turns out that we are emitting lots of warnings during
bootstrap because bootstrap tools are built with the default compiler
flags and ignore the warnings flags that are set in bsd.sys.mk.

Looking at git blame, it appears that MK_WARNS=no has been passed since
rS112869, replacing the -DNO_WERROR option that was added in rS87775.

This commit changes MK_WARNS=no back to -DNO_WERROR. We need to pass
-DNO_WERROR, since the system compiler might have new warnings that we
don't know about yet, and we shouldn't fail the build in that case.

f7ff7baaf6 crunchgen: fix NULL-deref bug introduced in r364647
While porting over the local changes from CheriBSD for upstreaming, I
accidentally committed a broken version of find_entry_point(): we have to
return NULL if the value is not found instead of a value with
ep->name == NULL, since the checks in main were changed to check ep instead
of ep->name for NULL.

This only matters if the crunched tool cannot be found using normal lookup
and one of the fallback paths is used, so it's unlikely to be triggered
in rescue. However, I noticed that one of our CheriBSD test scripts was
failing to run commands under `su` on minimal disk images where all
binaries are hardlinks to a `cheribsdbox` tool generated with crunchgen.

This also updates the bootstrapping check in Makefile.inc1 to bootstrap
crunchgen up to the next version bump.

0ac8aa55da pkgbase: Add incremental packages
This adds a new target update-packages which will create the new packages
compared to the last run.

This is how to use it:
At this point we cut a release
$ make buildworld ...
$ make buildkernel
$ make packages

    There is now a PKG_VERSION directory with latest link pointing to it
    Distribute the packages to server

$ something something that update the source tree
$ make buildworld ...
$ make buildkernel
$ make update-packages
You know have a PKG_VERSION directory in the REPODIR and latest link pointing to it.
In PKG_VERSION dir only the packages which differs from the latest run are
named PKG_VERSION, otherwise the old packages are there.

The process is :
Build the new packages in the PKG_VERSION directory
Compare the internal data with the PKG_VERSION_FROM version. The comparison is done
by checking the internal hash of the packages.
By default PKG_VERSION_FROM is set to what the latest link points to.
If the old and new version matches, we rm the new package and cp the old one.

3ac62888fc Significantly speed up mkimg_test
It turns out that the majority of the test time for the mkimg tests isn't
mkimg itself but rather the use of jot and hexdump which can be quite slow
on emulated platforms such as QEMU.

On QEMU-RISC-V this reduces the time for `kyua test mkimg_test` from 655
seconds to 200. And for CheriBSD on QEMU-CHERI this saves 4-5 hours (25%
of the time for the entire testsuite!) since jot ends up triggering slow
functions inside the QEMU emulation a lot.

e307eb94ae loader: zfs should support bootonce an nextboot
bootonce feature is temporary, one time boot, activated by
"bectl activate -t BE", "bectl activate -T BE" will reset the bootonce flag.

By default, the bootonce setting is reset on attempt to boot and the next
boot will use previously active BE.

By setting zfs_bootonce_activate="YES" in rc.conf, the bootonce BE will
be set permanently active.

bootonce dataset name is recorded in boot pool labels, bootenv area.

in case of nextboot, the nextboot_enable boolean variable is recorded in
freebsd:nvstore nvlist, also stored in boot pool label bootenv area.
On boot, the loader will process /boot/nextboot.conf if nextboot_enable
is "YES", and will set nextboot_enable to "NO", preventing /boot/nextboot.conf
processing on next boot.

bootonce and nextboot features are usable in both UEFI and BIOS boot.

To use bootonce/nextboot features, the boot loader needs to be updated on disk;
if loader.efi is stored on ESP, then ESP needs to be updated and
for BIOS boot, stage2 (zfsboot or gptzfsboot) needs to be updated
(gpart or other tools).

At this time, only lua loader is updated.

no matter where you're building in the src tree without breaking things
outside of the tree.

Crunchgen has been updated as a bootstrap tool to work on this change
because it needs r365605 at a minimum to succeed. The cleanup necessary to
successfully walk over this change on WITHOUT_CLEAN builds has been added.

185e8af021 installworld: run certctl rehash after installation completes
This was originally introduced back in r360833, and subsequently reverted
because it was broken for -DNO_ROOT builds and it may not have been the
correct place for it.

While debatably this may still not be 'the correct place,' it's much cleaner
than scattering rehashes all throughout the tree. brooks has fixed the issue
with -DNO_ROOT by properly writing to the METALOG in r361397.

Do note that this is different than what was originally committed; brooks
had revisions in D24932 that made it actually use the revised unprivileged
mode and write to METALOG, along with being a little more friendly to
foreign crossbuilds and just using the certctl in-tree.
