Building share/examples/tests with clang 18 results in a few warnings
like:
share/examples/tests/tests/plain/printf_test.c:67:6: error: 'snprintf' will always be truncated; specified size is 10, but format string expands to at least 17 [-Werror,-Wformat-truncation]
67 | if (snprintf(buffer, sizeof(buffer), "0123456789abcdef") != 16)
| ^
Since these tests are meant as an example of testing snprintf overflow,
suppress the warnings.

Python test scripts get processed (to add the `#! /usr/libexec/
atf_pytest_wrapper` shebang line), into a .xtmp file, and installed from
there. However, as there was no dependency of this .xtmp file on the
original file we kept reinstalling the .xtmp file, even if the original
had been edited already.
This could cause great confusion when debugging python test scripts.

The tmpfs memory reserve defaulted to 4 MB, and other than that,
all of available memory + swap could be allocated to tmpfs files.
This was dangerous, as the page daemon attempts to keep some memory
free, using up swap, and then resulting in processes being killed.
Increase the reserve to a fraction of available memory + swap at
file system startup time. The limit is expressed as a percentage
of available memory + swap that can be used, and defaults to 95%.
The percentage can be changed via the vfs.tmpfs.memory_percent sysctl,
recomputing the reserve with the new percentage but the initial
available memory + swap. Note that the reserve can also be set
directly with an existing sysctl, ignoring the percentage. The
previous behavior can be specified by setting vfs.tmpfs.memory_percent
to 100.
Add sysctl for vfs.tmpfs.memory_percent and the pre-existing
vfs.tmpfs.memory_reserved to tmpfs(5).

A deprecation notice was added to the bus_dma(9) man page by scottl@ in
September 2020 discouraging the use of filter functions. I've performed
an attentive check of all callers in the tree and everything that exists
today passes NULL for both filtfunc and filtarg. Thus, we should start
returning EINVAL if these arguments are non-NULL to prevent new usages
from popping up. Update the man page to be more clear about this.
The deprecation notice is present since at least 13.0-RELEASE, so this
is the appropriate step for the lifetime of 15, without actually
breaking the driver API. Stable branches will emit a warning instead.
This change enables the removal of a fair amount of unused complexity
across the various busdma implementations.

It is possible to reach this function from ddb via the "reset" command.
When this happens, we don't actually exit kdb, meaning we never execute
the latter steps of kdb_break() to restore the system state (e.g.
re-enable scheduler).
Therefore, we should not clear the kdb_active flag in this function, as
the debugger is still active. Put differently, kern_reboot() is not an
authority on kdb state, and should not touch it. The original motivation
for this assignment is not clear; I have checked thoroughly and I am
convinced it is not required by any reset code.
This fixes an edge case where a panic can be triggered during reset from
ddb:
1. Enter ddb via keyboard break sequence (KERNEL_PANICKED() == false &&
td->td_critnest > 0)
2. Execute the "reset" command
3. kern_reboot() sets kdb_active = false
4. A witness_checkorder() call via shutdown handler sees !kdb_active
and panics

The tranditional build makes multiple passes through the tree.
The DIRDEPS_BUILD visits each directory only once per architecture,
thus makefiles should be able to everything they need in a single pass.
The use of TZS!= when doing make(*install*)
only works if the directory has previously been visited to do zoneinfo
since before the zoneinfo target is run TZS will be empty.
To fix this, have the zoneinfo target capture the list of files to
zoneinfo, and install-zoneinfo use that list.
Rename that target to zonefiles - since that is now what it does.
This is more efficient - we only gather the list of zones when it is
likely to have changed, and allows the makefile to do everything in a
single pass.

change directory commands that should only have an effect on the
other commands in the same line. Otherwise, if make is not running in
compatibility mode (for example, when -j flag is specified), commands
would be executed in a single shell and lines following the "cd" might
not work as expected.
