fuse(4) was heavily instrumented with debug printf statements that could
only be enabled with compile-time flags. They fell into three basic groups:
1. Totally redundant with dtrace FBT probes. These I deleted.
2. Print textual information, usually error messages. These I converted to
SDT probes of the form fuse:fuse:FILE:trace. They work just like the old
printf statements except they can be enabled at runtime with dtrace. They
can be filtered by FILE and/or by priority.
3. More complicated probes that print detailed information. These I
converted into ad-hoc SDT probes.
Also, de-inline fuse_internal_cache_attrs. It's big enough to be a regular
function, and this way it gets a dtrace FBT probe.
This commit is a merge of r345304, r344914, r344703, and r344664 from
projects/fuse2.

From Jake:
iflib_if_transmit returns ENOBUFS when the device is down, or when the
link isn't active.
This was changed in r308792 from return (0), so that the function
correctly reports an error that it was unable to transmit.
However, using ENOBUFS can cause some network applications to produce
the following or similar errors:
"ping: sendto: No buffer space available"
This is a bit confusing as the real cause of the issue is that the
network device is down.
Replace the ENOBUFS return with ENETDOWN to indicate more clearly that
the reason for the failure to send is due to the network device is
offline.
This will cause the error message to be reported as
"ping: sendto: Network is down"

The iflib_device_register function takes the CTX lock before calling
IFDI_ATTACH_PRE, and releases it upon finishing the registration.
Mirror this process in iflib_pseudo_register, so that we always hold the
CTX lock during the attach process when registering a pseudo interface
or a regular interface.
This was caught by code inspection while attempting to analyze where the
CTX lock was held.

CAM IOCTL interfaces traditionally mapped user-space data buffers to KVA.
It was nice originally, but now it takes too much to handle respective
TLB shootdowns, while small kernel memory allocations up to 64KB backed
by UMA and accompanied by copyin()/copyout() can be much cheaper.
For large buffers mapping still may have sense, and unmapped I/O would
be even better, but the last unfortunately is more tricky, since unmapped
I/O API is too specific to struct bio now.

lagg_bcast_start appeared to have a bug in that was using the last
lagg port structure after exiting the epoch that was keeping that
structure alive. However, upon further inspection, the epoch was
already entered by the caller (lagg_transmit), so the epoch enter/exit
in lagg_bcast_start was actually unnecessary.
This commit generally removes uses of the net epoch via LAGG_RLOCK to
protect the list of ports when the list of ports was already protected
by an existing LAGG_RLOCK in a caller, or the LAGG_XLOCK.
It also adds a missing epoch enter/exit in lagg_snd_tag_alloc while
accessing the lagg port structures. An ifp is still accessed via an
unsafe reference after the epoch is exited, but that is true in the
current code and will be fixed in a future change.

This makes it easier for googletest users to leverage googletest, instead of
forcing them to plug GTEST_CXXFLAGS into CXXFLAGS manually (resulting in
unnecessary duplication).
I will be following this up with a more proper fix in src.libnames.mk, as
src.libnames.mk should be automatically adding this directory to
CFLAGS/CXXFLAGS when private libraries are referenced. Not doing so can result
in mismatches between base-provided private library's and ports-provided
library's headers.
While here, tweak the comment to clarify what the intent is behind spamming
CXXFLAGS.

Consider a bridge0 with em0 and em1 members. Traffic rx'd by em0 and
transmitted by bridge0 through em1 gets accounted for in IPACKETS/IBYTES
and bridge0 bpf -- assuming it's not unicast traffic destined for em1.
Unicast traffic destined for em1 traffic is not accounted for by any
mechanism, and isn't pushed through bridge0's bpf machinery as any other
packets that pass over the bridge do.
Fix this and simplify GRAB_OUR_PACKETS by bailing out early if it was rx'd
by the interface that it was addressed for. Everything else there is
relevant for any traffic that came in from one member that's being directed
at another member of the bridge.

Relative directories may appear in the line number program for a CPU if
files were included via a relative path, for instance with "-I.".
Previously, dwarf_srclines(3) and dwarf_srcfiles(3) would return the
relative path, so addr2line, for instance, would do the same. However,
we can get an absolute path by prepending the compilation directory, so
change libdwarf to do that to improve compatibility with GNU binutils

Reading of single pixels didn't look under the cursor.
Copying of 1x1 bitmaps didn't look under the cursor for either reading
or writing.
Copying of larger bitmaps looked under the cursor for at most the
destination.
Copying of larger bitmaps looked under a garbage cursor (for the Display
bitmap) when the destination is a MEMBUF. The results are not used, so
this only wasted time and flickered the cursor.
Writing of single pixels looked under a garbage cursor for MEMBUF
destinations, as above except this clobbered the current cursor and
didn't update the MEMBUF. Writing of single pixels is not implemented
yet in depths > 8. Otherwise, writing of single pixels worked. It was
the only working case for accessing pixels under the cursor.
Clearing of MEMBUFs wasted time freezing the cursor in the Display bitmap.
The fixes abuse the top bits in the color arg to the cursor freezing
function to control the function. Also clear the top 8 bits so that
applications can't clobber the control bits or create 256 aliases for
every 24-bit pixel value in depth 32.
Races fixed:
Showing and hiding the cursor only tried to avoid races with the mouse
event signal handler for internal operations. There are still many
shorter races from not using volatile or sig_atomic_t for the variable
to control this. This variable also controls freezes, and has more
complicated states than before.
The internal operation of unfreezing the cursor opened a race window
by unsetting the signal/freeze variable before showing the cursor.

depths for the source and target are not supported. The bits for higher
numbered planes (mostly for red) were either not copied or were copied to
lower numbered planes for nearby pixels.
Quick fix for creation of mouse cursor bitmaps in all depths. This fix is
only complete for the default lightwhite cursor with a black frame.
Even the lightwhite and black colors are hard to find. The templates
use 0xff for lightwhite, but that means brightblue in the simplest mode
(Truecolor depth 24). Other modes are even more complicated -- they are
singly or doubly indirect throught palette(s) and changing of the palettes
by applications is supported.
Details:
Replicate the template value for Truecolor modes to fill out the target
depth (and more for depths not a multiple of 8). Do this for every
drawing of the cursor so that it sort of works for mouse cursor bitmaps
set by applications.
Use 0xf for lightwhite in most other modes. Only do this for the
default cursor so that it doesn't affect mouse cursor bitmaps set by
applications. 0xf mostly works because it was originally for CGA
lightwhite and is emulated using 1 or 2 indirections on EGA and VGA.
0x3f (EGA white) and 0xff (VGA black) direct palette indexes mostly
don't work since backwards compatibility inhibits or prevents them
representing lightwhite. But 0x3f (EGA white) must be used for mode
37 (VGA_MODEX) (320x240x8 V) since this mode is closer to EGA than VGA.

finding no differences in the output). For zfsldr I compared objdump

Direct /etc/rc exec was introduced in r337321, with a fallback to
passing it to sh if direct exec fails. "Can't exec" is slightly
misleading in this case (the script is still executed, just not
directly).
In most cases kernel.bootfile is populated from the information
provided by loader(8). There are certain scenarios when loader
is not available, for instance when kernel is loaded by u-boot
or some other BootROM directly. In this case the default value
"/kernel" points to invalid location and breaks some functinality,
like using installkernel on self-hosted system or dtrace's CTF
lookup. This can be fixed by setting the value manually but the
default that reflects correct location is better than default that
points to invalid one.
Current default was set around FreeBSD 1, when "/kernel" was the
actual path. Transition to /boot/kernel/kernel happened circa FreeBSD 3.
