Add a new __sentinel attribute.
The sentinel attribute was originally implemented in OpenBSD's gcc and
later adopted by upstream GCC 4.0 (and clang). From the OpenBSD's
gcc-local manpage:
- gcc recognizes the extra attribute __sentinel__, which can be used to
mark varargs function that need a NULL pointer to mark argument
termination, like execl(3). This exposes latent bugs for 64-bit
architectures, where a terminating 0 will expand to a 32-bit int, and
not a full-fledged 64-bits pointer.
Make the system queue header file fully usable within C++ programs by
adding macros to define class lists.
This change is backwards compatible for all use within C and C++
programs. Only C++ programs will have added support to use the queue
macros within classes. Previously the queue macros could only be used
within structures.
The queue.3 manual page has been updated to describe the new
functionality and some alphabetic sorting has been done while
at it.

Only initialize libedit when necessary
The code path to support units conversions from the command line
need not initialize neither libedit nor the history. Therefore, only do
that when in interactive mode.
This hides the issue reported in PR bin/201167 whereby running commands
of the form 'echo "$(units ft in)"' would corrupt the terminal. The real
issue causing the corruption most likely still remains somewhere.
Remove unneeded data dependency, currently imposed by
atomic_load_acq(9), on it source, for x86.
Right now, atomic_load_acq() on x86 is sequentially consistent with
other atomics, code ensures this by doing store/load barrier by
performing locked nop on the source. Provide separate primitive
__storeload_barrier(), which is implemented as the locked nop done on
a cpu-private variable, and put __storeload_barrier() before load, to
keep seq_cst semantic but avoid introducing false dependency on the
no-modification of the source for its later use.
Note that seq_cst property of x86 atomic_load_acq() is not documented
and not carried by atomics implementations on other architectures,
although some kernel code relies on the behaviour. This commit does
not intend to change this.

Change detection for the gnu_inline attribute.
According to the GCC documentation:
"This attribute is available in GCC 4.1.3 and later. It is available
if either of the preprocessor macros __GNUC_GNU_INLINE__ or
__GNUC_STDC_INLINE__ are defined."
We don't keep the gcc granularity up to the minor number so it's
better to use the documented way. Current clang defines both
macros.
Handle errors from background write of the cylinder group blocks.
First, on the write error, bufdone() call from ffs_backgroundwrite()
panics because pbrelvp() cleared bp->b_bufobj, while brelse() would
try to re-dirty the copy of the cg buffer. Handle this by setting
B_INVAL for the case of BIO_ERROR.
Second, we must re-dirty the real buffer containing the cylinder group
block data when background write failed. Real cg buffer was already
marked clean in ffs_bufwrite(). After the BV_BKGRDINPROG flag is
cleared on the real cg buffer in ffs_backgroundwrite(), buffer scan
may reuse the buffer at any moment. The result is lost write, and if
the write error was only transient, we get corrupted bitmaps.
We cannot re-dirty the original cg buffer in the
ffs_backgroundwritedone(), since the context is not sleepable,
preventing us from sleeping for origbp' lock. Add BV_BKGDERR flag
(protected by the buffer object lock), which is converted into delayed
write by brelse(), bqrelse() and buffer scan.

This is fine for the FreeBSD loader, because it completely ignores p_paddr
and instead uses p_vaddr with a hardcoded offset. Other loaders however
acknowledge p_paddr (like the Xen ELF loader), in which case they will try
to load the kernel at the wrong place. Fix this by adding an AT keyword to
the first section specifying the physical address, other sections will
follow suit, so it ends up looking like:

Tested on bare metal using the native FreeBSD loader and grub2 from TRUEOS.
Split the DMAR unit domains and contexts. Domains carry address space
and related data structures. Contexts attach requests initiators to
domains. There is still 1:1 correspondence between contexts and
domains on the running system, since only busdma currently allocates
them, using dmar_get_ctx_for_dev().
Large part of the change is formal rename of the ctx to domain, but
patch also reworks the context allocation and free to allow for
independent domain creation.
The helper dmar_move_ctx_to_domain() is introduced for future use, to
reassign request initiator from one domain to another. The hard issue
which is not yet resolved with the context move is proper handling (or
reserving) RMRR entries in the destination domain as required by ACPI
DMAR table for moved context.
