abd_iter_page: rework to handle multipage scatterlists
Previously, abd_iter_page() would assume that every scatterlist would
contain a single page (compound or no), because that's all we ever
create in abd_alloc_chunks(). However, scatterlists can contain multiple
pages of arbitrary provenance, and if we get one of those, we'd get all
the math wrong.
This reworks things to handle multiple pages in a scatterlist, by
properly finding the right page within it for the given offset, and
understanding better where the end of the page is and not crossing it.

mailwrapper(8): change behaviour if mailer.conf cannot be opened
Previously, mailwrapper(8) would default to invoking _PATH_DEFAULTMTA
(i.e., dma) if mailer.conf couldn't be opened for any reason, including
transient errors like ENFILE. This behaviour is undesirable, because if
the administrator has configured a different MTA in mailer.conf, they
almost certainly don't want mailwrapper to unpredictably fall back to
the compiled-in default; and in any case, the default MTA is probably
not running, meaning the mail may be queued and then never delivered,
which is worse than not accepting it to begin with.
Change this behaviour depending on why mailer.conf can't be opened:
- If it doesn't exist, keep the existing behaviour of falling back to
the default MTA, on the assumption that this is a reasonable default
if mailer.conf hasn't been configured at all.
- If it cannot be opened for any other reason, do not invoke an MTA and
instead return an error to the caller.

share/mk/bsd.cpu.mk: add F16C feature for i386 and amd64 architectures
As discussed in bug 278417, some ports require the F16C instruction set
to compile, but there is no way yet to detect whether the currently
chosen CPUTYPE supports this feature.
Add the feature to the MACHINE_CPU variable, for each processor that
supports it. The list of processors was extracted from clang 18's -dM
output, filtered on the __F16C__ define.
Add preliminary in-tree CI infrastructure for developers
The goal of this project is to integrate the relevant scripts from the
FreeBSD-CI project (https://github.com/freebsd/freebsd-ci) into the src
repository. This allows developers to run the test suite similar to how
it is executed on ci.freebsd.org, and eventually, have it directly used
by our CI system. This effort is also part of the workflow improvement
project, aiming to incorporate pre-merge testing.
Current Features:
* Does smoke tests using either bhyve(amd64 only) or qemu(Non x86_64 or
when defined USE_QEMU=1). Currently defined CITYPE=smoke. Once we have
added full tests we can also utilize something like CITYPE=full
* Most of the resources are dynamically allocated based on available
resources in the host
* If CPU supports POPCNT or vmm can be loaded then bhyve is used for
amd64 otherwise automatically installs and uses qemu@nox11
* When required third party applications or packages for booting non-x86
images are automatically installed
Current Limitation:
* Does not support full tests like the one in our Jenkins
* At this moment this is also not suitable to be used in our Jenkins
platform as the jobs are divided in multiple smaller tasks and
artifacts are moved here and there which are not exactly the scenario
for individual developers.
Future Works:
* Add full tests like the one in ci.freebsd.org
* Add different tests or options to disable some tests
* Add test profiles full
* Possibly add test through Cloud Providers like AWS/GCP/Azure or Cirrus
or Github Actions
* Update documentation

rather than exit with 0 and print to stderr
Example output:
% ./bsdbox
