tls 8a012bd83f The rnd pseudo-device is not really optional, because it is in the same
source file as the entropy-pool code itself.  Move it to std.  This
will be cleaned up more when I split the sources up as they should be.

This fixes build breaks on several ports.  Thanks to Havard Eidnes for
pointing them out.

rmind 40cf6f3659 Remove uarea swap-out functionality:
- Addresses the issue described in PR/38828.
- Some simplification in threading and sleepq subsystems.
- Eliminates pmap_collect() and, as a side note, allows pmap optimisations.
- Eliminates XS_CTL_DATA_ONSTACK in scsipi code.
- Avoids few scans on LWP list and thus potentially long holds of proc_lock.
- Cuts ~1.5k lines of code.  Reduces amd64 kernel size by ~4k.
- Removes __SWAP_BROKEN cases.

Tested on x86, mips, acorn32 (thanks <mpumford>) and partly tested on
acorn26 (thanks to <bjh21>).

Discussed on <tech-kern>, reviewed by <ad>.

matt 0dee8e59c9 Add [default] option to make UAREAs swappable. Disabling the option makes
them unswappable and therefore allocatable using KSEG/BAT/etc.

ad d3d0b437b0 - Conditionalise POSIX aio and mqueue, but include them by default.
- Add a COMPAT_NETBSD attribute. Emit if any compat options are used.

ad 18af8ee9bd Add cpuctl(8). For now this is not much more than a toy for debugging and
benchmarking that allows taking CPUs online/offline.

elad 5f7169ccb1 First take at security model abstraction.
- Add a few scopes to the kernel: system, network, and machdep.

- Add a few more actions/sub-actions (requests), and start using them as
  opposed to the KAUTH_GENERIC_ISSUSER place-holders.

- Introduce a basic set of listeners that implement our "traditional"
  security model, called "bsd44". This is the default (and only) model we
  have at the moment.

- Update all relevant documentation.

- Add some code and docs to help folks who want to actually use this stuff:

  * There's a sample overlay model, sitting on-top of "bsd44", for
    fast experimenting with tweaking just a subset of an existing model.

    This is pretty cool because it's *really* straightforward to do stuff
    you had to use ugly hacks for until now...

  * And of course, documentation describing how to do the above for quick
    reference, including code samples.

All of these changes were tested for regressions using a Python-based
testsuite that will be (I hope) available soon via pkgsrc. Information
about the tests, and how to write new ones, can be found on:

	http://kauth.linbsd.org/kauthwiki

NOTE FOR DEVELOPERS: *PLEASE* don't add any code that does any of the
following:

  - Uses a KAUTH_GENERIC_ISSUSER kauth(9) request,
  - Checks 'securelevel' directly,
  - Checks a uid/gid directly.

(or if you feel you have to, contact me first)

This is still work in progress; It's far from being done, but now it'll
be a lot easier.

Many thanks to YAMAMOTO Takashi, Matt Thomas, and Christos Zoulas for help
stablizing kauth(9).

Full credit for the regression tests, making sure these changes didn't break
anything, goes to Matt Fleming and Jaime Fournier.

Happy birthday Randi! :)

matt 9e0ec4816e Make PTRACE and COREDUMP optional. Make the default (status quo) by putting
them in conf/std.

rpaulo de8db47547 Add support for RFC 3542 Adv. Socket API for IPv6 (which obsoletes 2292).
* RFC 3542 isn't binary compatible with RFC 2292.
* RFC 2292 support is on by default but can be disabled.
* update ping6, telnet and traceroute6 to the new API.
