illumos/illumos-gate@79809f9cf402f130667349b2d4007ecd65d63c6f
https://github.com/illumos/illumos-gate/commit/79809f9cf402f130667349b2d4007ecd65d63c6f

https://www.illumos.org/issues/8269
It seems that currently normalization of stddev aggregation is done
incorrectly.
We divide both the sum of values and the sum of their squares by the
normalization factor. But we should divide the sum of squares by the
normalization factor squared to scale the original values properly.

Improve collation string and locales support

Merge collation support from Illumos and DragonflyBSD.

Locales are now generated with the new localedef(1) tool from CLDR POSIX files.
The generated files are now identified as "BSD 1.0" format.

The libc now only read "BSD 1.0" locales definitions, all other version will be
set to "C"
The localedef(1) tool has been imported from Illumos and modified to use tree(3)
instead of the CDDL avl(3)
A set of tool created by edwin@ and extended by marino@ for dragonfly has been
added to be able to generate locales and the Makefiles from the vanilla CLDR
unicode databases + a universal UTF-8 charmap (by marino@)
Update the locales to unicode v27
Given our regex(3) does not support multibyte (yet) it has been forced to always
use locale C
Remove now unused colldef(1) and mklocale(1)
Finish implementing the numeric BSD extension for ctypes
The number of supported locales has grown from 175 to 250 locales. Among the new
locales: 6 Arabic locales (AE EG JO MA QA SA), Different variations of spanish
locales.
Added new 3 components locales for mn_Cyrl_MN, sr_Cyrl_RS sr_Latn_RS,
zh_Hans_CN, zh_Hant_HK and zh_Hant_TW. Some aliases has been for 2 components
version when possible.

Thanks: Garrett D'Amore (Illumos) who made sure all his work was done under
BSD license!, Edwin Groothuis (edwin@) for the work he made on tools to be able
to generate locales definition usable in freebsd sources out of vanilla CLDR
definitions, John Marino (DragonflyBSD) who first merge the Illumos work into
Dragonfly and spent hours tracking down bugs.

Use kern_ioctl() rather than ioctl() for testing the FBT provider, since the
latter doesn't exist in FreeBSD. All the tests under fbtprovider pass now.

Port the SDT test now that it's possible to create SDT probes that take
seven arguments.

The original test uses Solaris' uadmin system call to trigger the test
probe; this change adds a sysctl to the dtrace_test module and gets the test
program to trigger the test probe via the sysctl handler.

The test is currently failing on amd64 because of some bugs in the way that
probe arguments beyond the first five are obtained - these bugs will be
fixed in a separate change.

Unfortunately the change from upstream was made in such a way

Import the dtrace llquantize test files from the vendor area.

Now that we have an illumos vendor area, import the llquantize
test files directly from there to make it easier to track the
code provenance.

Special thanks to Martin Matuska for populating the illumos
vendor area.

Bring llquantize support into Dtrace.

Bryan Cantrill implemented the equivalent of semi-log graph

Special thanks to Mark Peek for providing fix to an
assertion and to Fabian Keill for testing the port.
