When this option is enabled, only gdb and kgdb are installed to
/usr/libexec for use by crashinfo(8). Other bits of GDB such as
gdbserver and gdbtui are not installed. For this option to be
effective, GDB must be enabled.
Rework r317094 to re-enable GDB on all platforms but enable
GDB_LIBEXEC on platforms for which the GDB in ports is a superset of
functionality.

This feature includes code to allow a system with compressed ARC enabled to
send data in its compressed form straight out of the ARC, and receive data in
its compressed form directly into the ARC.

We should have longer, more readable versions of the ZFS send / recv options.

patm(4) devices.
Maintaining an address family and framework has real costs when we make
infrastructure improvements. In the case of NATM we support no devices
manufactured in the last 20 years and some will not even work in modern
motherboards (some newer devices that patm(4) could be updated to
support apparently exist, but we do not currently have support).
With this change, support remains for some netgraph modules that don't
require NATM support code. It is unclear if all these should remain,
though ng_atmllc certainly stands alone.
Note well: FreeBSD 11 supports NATM and will continue to do so until at
least September 30, 2021. Improvements to the code in FreeBSD 11 are
certainly welcome.

The NFSv4 RFCs give a server the option of allowing the use of an open
stateid for write access to be used for a Read operation.
This patch enables this by default and adds a sysctl to disable it,
for anyone who does not want this capability.
Allowing this is particularily useful for a pNFS Data Server (DS), since
they are not permitted to allow the use of special stateids.
Discovered during recent testing of the pNFS server under development.

usr.bin/diff/diffreg.c: In function 'change':
usr.bin/diff/diffreg.c:1085: warning: 'i' may be used uninitialized in this function
This version of gcc is not smart enough to see that 'i' cannot actually
be used unitialized. However, the variable is confusingly re-used, so
it is better to give it another name, and clearly initialize it before
attempting to use it.

Hyper-V hot channel effect:
Operation latency on hot channel is only _half_ of the operation
latency on cold channels.
This commit takes the advantage of the above Hyper-V host channel
effect, and can reduce more than 75% latency and more than 50%
latency stdev, i.e. lower and more stable/predictable latency,

This patch sets the default uid/gid values for "nobody" and "nogroup"
to the values in the password and group databases. Normally nfsuserd(8)
will override these with whatever is in the password/group databases,
so these values are only used when the databases entries aren't available.
It would be nice to use the definitions in sys/conf.h, but those are
in the _KERNEL section of the file.

An NFSv4 server has the option of allowing a Read to be done using a Write
Open. If this is not allowed, the server will return NFSERR_OPENMODE.
This patch attempts the read with a write open and then disables this
if the server replies NFSERR_OPENMODE.
This change will avoid some uses of the special stateids. This will be
useful for pNFS/DS Reads, since they cannot use special stateids.
It will also be useful for any NFSv4 server that does not support reading
via the special stateids. It has been tested against both types of NFSv4 server.

colors.
Colors are still hard-coded as 15 (normally lightwhite) for the interior
and 0 (normally black) for the border, but these are now values used in
2 expressions instead of built in to the algorithm. The algorithm used
a fancy and/or method, but this gives no control over the colors except
and'ing all color planes off gives black and or'ing all color planes on
gives lightwhite. Just draw the border and interior in separate colors
using the same method as for characters, including its complications to
optimize for VGA adaptors. Optimization is not really needed here, but
for the VGA case it avoids being slower than the and/or method. The
optimization is worth about 30%.
