   Remove more IPI code when building uniprocessor kernels

   The "iic" instance does not depend on i2c_bitbang, so it should not
   express it as a dependency.  That's the responsibility of the back-ends
   that do require it.

   sharkiic uses i2c_bitbang, and thus should express it as a dependency.

   No need to include i2c_bitbang.h -- it's not used.

   Does not use i2c_bitbang, so should not depend on it.

   kobj_load(): Consider ELF{32,64}_MACHDEP_FLAGS_OK().

   Elide some ipi references when building !MULTIPROCESSOR

   fix various typos in comments.

   Only declare LOCKSTAT_* variables when we are compiling for a MULTIPROCESSOR
   kernel.

   Update to Unicode 17

   Based on perl 5.44.0

   devhandle_impl_subclass(): make sure a handle never has the type INVALID.

   Elide subr_ipi.c for non-MP configurations.

   Elide subr_ipi.c for non-MP configurations.

   Slim this down for non-MP configurations.

   Don't bother signalling remote CPUs on non-MP configurations.

   Don't bother signalling remote CPUs on non-MP configurations.

   Don't bother with the "no disk label" message.  It's not particularly
   useful, and is downright confusing if the disk has some other sort of
   partition scheme (such at GPT).

   Elide subr_interrupt.c on non-MP configurations.

   +ZDR  Zero Data Retention

   t_dlclose_thread: Make timeouts manifest more predictably.

   And use SIGABRT to get stack traces.

   PR lib/59751: dlclose is not MT-safe depending on the libraries
   unloaded

   No longer need to expose pmap_kernel_pte().

   SCSI-2 and later define READ(6) as optional and READ(10) as mandatory
   and some devices (e.g. the Linux iSCSI tgtd) reject the small commands.

   MODE_SENSE(6) and MODE_SENSE(10) can both be optional, so it's possible
   that a SCSI-2 device only implements READ(10) and MODE_SENSE(6), which
   then needs further refinement.

   t_dlclose_thread: Test recursive dlopen/dlclose too.

   Simple test first:

   - h_helper_recurdso dlopens h_helper_dso2
   - h_helper_dso2 needs h_helper_dso1

   When dlopening h_helper_recurdso, the initialization order must be:

   ENTER h_helper_recurdso
   -> h_helper_dso1
   -> h_helper_dso2
   LEAVE h_helper_recurdso

   For the more complex test, we have the relations:

   - h_helper_recurdso2 needs h_helper_recurdso
   - h_helper_recurdso dlopens h_helper_dso2
   - h_helper_dso2 needs h_helper_dso1

   Add verite3d device.

   Add support for experimental Rendition Verite 3D acceleration interface.

   This allow userland process to load 3D firmware (like v2000gl.uc) and
   execute it on the chip's RISC CPU. It also provides the necessary support
   infrastructure like basic VRAM accounting and ability to feed commands
   and data through DMA.

   In conjuction with customized userland Mesa, this allows OpenGL 1.x
   workloads to run accelerated on the Verite.

   While here, add related debugging facilities.
