After years in the making, lualoader is ready to make its debut. Both
flavors of loader are still built by default, and may be installed as
/boot/loader or /boot/loader.efi as appropriate either by manually creating
hard links or using LOADER_DEFAULT_INTERP as documented in build(7).

Instead of doing a second pass to skip empty lines if we've specified -I, go
ahead and check both at once. Ignore critera has been split out into its own
function to try and keep the logic cleaner.
As noted by cem in r338035, coccinelle invokes diff(1) with the -B flag.
This was not previously implemented here, so one was forced to create a link
for GNU diff to /usr/local/bin/diff
Implement the -B flag and add some primitive tests for it. It is implemented
in the same fashion that -I is implemented; each chunk's lines are scanned,
and if a non-blank line is encountered then the chunk will be output.
Otherwise, it's skipped.

Without this patch, some CS4614 cards will need users to reload the driver manually or

Inspired by r338025, just remove the element size parameter to the
MODULE_PNP_INFO macro entirely. The 'table' parameter is now required to
have correct pointer (or array) type. Since all invocations of the macro
already had this property and the emitted PNP data continues to include the
element size, there is no functional change.
Mostly done with the coccinelle 'spatch' tool:
$ cat modpnpsize0.cocci
@normaltables@
identifier b,c;
expression a,d,e;
declarer MODULE_PNP_INFO;
@@
MODULE_PNP_INFO(a,b,c,d,
-sizeof(d[0]),
e);
@singletons@
identifier b,c,d;
expression a;
declarer MODULE_PNP_INFO;
@@
MODULE_PNP_INFO(a,b,c,&d,
-sizeof(d),
1);
$ rg -l MODULE_PNP_INFO -- sys | \
xargs spatch --in-place --sp-file modpnpsize0.cocci
(Note that coccinelle invokes diff(1) via a PATH search and expects diff to
tolerate the -B flag, which BSD diff does not. So I had to link gdiff into
PATH as diff to use spatch.)

This should stop kldxref searching beyond the end of .rodata when it
processes relocations, and emitting "unhandled relocation type" errors,
at least on i386.
This is very primitive code to inspect the PCI error state and AER
error state, dump the log and clear errors, from ddb.
pci_print_faulted_dev() is made external to allow calling it from
other places. It was called from NMI handler but this chunk is not
included.
Also there is a tunable-controlled code to clear AER on device attach,
disabled by default.
All this code was useful to me when I debugged ACPI_DMAR failures (not
faults) long time ago.

The fallback logic was broken if hints were found in multiple environments.
If we found a hint in either the loader environment or the static
environment, fallback would be incremented excessively when we returned to
the environment-selection bits. These checks should have also been guarded
by the fbacklvl checks. As a result, fbacklvl could quickly get to a point
where we skip either the static environment and/or the static hints
depending on which environments contained valid hints.
The impact of this bug is minimal, mostly affecting mips boards that use
static hints and may have hints in either the loader environment or the
static environment.
There may be better ways to express the searchable environments and
describing their characteristics (immutable, already searched, etc.) but
this may be revisited after 12 branches.

When coding the pNFS server, I added vn_start_write() calls in nfsrv_copymr()
done while the vnodes were locked, not realizing I had introduced LORs and
possible deadlock when an exported file system on the MDS is suspended.
This patch fixes the LORs by moving the vn_start_write() calls up to before
where the vnodes are locked. For "tvp", the vn_start_write() probaby isn't
necessary, because NFS mounts can't be suspended. However, I think doing
so is harmless.
Thanks go to kib@ for letting me know that I had introduced these LORs.
This patch only affects the behaviour of the pNFS server when pnfsdscopymr(8)
is used to recover a mirrored DS.
The domain and flags parameters suffice. In fact, the related functions
kmem_alloc_{attr,contig}_domain() don't have an arena parameter.

Some background: in the GSoC project, libbe/Makefile lived in lib/libbe. I
created projects/bectl branch, maintained the above for all of five
minutes before I misread Makefile.inc1 and decided that it couldn't possibly
build outside of cddl/, so I kicked the Makefile out into the cddl/ build
and all was good. The misreading was of the bit where .WAIT is added to
SUBDIR after lib, libexec but prior to building bin and cddl *only during
the install targets*, which is the critical part.
Fast forward- buildworld was still broken in my branch unbeknownst to me
because I didn't nuke my OBJDIR. Combing through Makefile.inc1 eventually
revealed the necessary magic to make sure that libbe's dependencies are
specified well enough, and it becomes clear what needs done to make a
non-cddl/ build work. This is an interesting prospect, because the build
split is kind of annoying to work with.
IGNORE_PRAGMA is added to avoid dropping WARNS by one more. This was
previously pulled in via cddl/Makefile.inc.
Instead of always running /bin/sh, allow the user to specify the command
to run. The jail is not removed when the command finishes. Meaning,
`bectl unjail` will still need to be run.
For example:
```
bectl jail newBE pkg upgrade
bectl ujail newBE

In the create-world-packages target we manually piece this together (unless
it is undefined), without the DISTDIR. Normally DISTDIR is empty (unset) and
no one notices. Now DISTDIR is a well known long-standing PORTS environment
variable and if that is set in the local environment the path to METALOG
is wrong as it no longer is ${DESTDIR}/METALOG.
Long-term we should start to avoid "publicly well known" names for global
variables, for now just piece ${DISTDIR} in as well. This allows
create-world-packages to continue if DISTDIR is set in the env.
When coding the pNFS server, I added several vn_start_write() calls done
while the vnode was locked, not realizing I had introduced LORs and
possible deadlock when an exported file system on the MDS is suspended.
This patch fixes this by removing the added vn_start_write() calls and
modifying the code so that the extant vn_start_write() call before the
NFS RPC/operation is done when needed by the pNFS server.
Flags are changed so that LayoutCommit and LayoutReturn now get a
vn_start_write() done for them.
When the pNFS server is enabled, the code now also changes the flags for
Getattr, so that the vn_start_write() is done for Getattr, since it may
need to do a vn_set_extattr(). The nfs_writerpc flag array was made global
to the NFS server and renamed nfsrv_writerpc, which is consistent naming
for globals in the NFS server.
Thanks go to kib@ for reporting that doing vn_start_write() while the vnode is
locked results in a LOR.
This patch only affects the behaviour of the pNFS server.
Originally, these tests accidentally used broadcast addresses when they
should've used unicast addresses. That the tests passed prior to r337736
was accidental.
