rcmds were removed in r32435 and these three man pages can trivially
drop the references.
There's still a reference in pts.4 because it describes a mode
(TIOCPKT_NOSTOP), and only lists rlogin/rlogind as examples of programs
that use that mode. To update later.

The driver was originally written with the name ads1115, but at the last
minute it got renamed to ads111x to reflect its support for many related
chips, but I forgot to update the manpage to match the renaming before
committing it all.

files.x86 is for the parts of the system that are common to both i386 and amd64

x86 needs sc, as does sparc64. powerpc doesn't use it by default, but some old
powermac notebooks do not work with vt yet for reasons unknonw. Even so, I've
removed it from powerpc LINT. It's not in daily use there, and the intent is to
100% switch to vt now that it works for that platform to limit support burden.
All the other architectures omit some or all of the screen savers from their
lint config. Move them to the x86 NOTES files and remove the exclusions. This
reduces slightly the number of savers sparc64 compiles, but since they are in
GENERIC, the overage is adequate and if someone reaelly wants to sort them out
in sparc64 they can sweat the details and the testing.

Since YP protocol definition uses the constant to declare
variable-size opaque byte strings, the change should be binary
compatible with existing installations which do not expose keys or
values larger than 1024 bytes.
All uses of local variables with YPMAXRECORD sizes were removed to
avoid insane stack use. On the other hand, variables with static
lifetime should be fine and only result in increased VA use.
Glibc made same change, increasing the allowed length for keys and
values in YP to 16M, in 2013.

In any pool without the extensible dataset feature flag already enabled,
creating a dataset with dedup set to use one of the new checksums would result
in the following panic as soon as any data was added:

Inspection showed that feature->fi_feature was 7, which is the value of
SPA_FEATURE_EXTENSIBLE_DATASET in the spa_feature enum.
Testing shows that the panic can be prevented by explicitly setting extensible
dataset as a dependency for the sha512, edonr, and skein feature flags.
Alternatively, the new checksums code could possibly be changed to obviate the
need for the dependency.

The race was introduced in r337669, the large dnode feature import from
ZoL. The problem was debugged by ZoL developers and then,
independently, on FreeBSD.
The fix is an early proposal by Brian Behlendorf:
50f32ed74e
This fix never went into ZoL. A larger change that was committed later
included a different solution because of the re-worked code.
Ideally, we want to revert this fix and re-synchronize FreeBSD large
dnode code with that in illumos (or newer ZoL). illumos has a later
import of the feature from ZoL that does not have the bug.
