bc093719ca Integrate the new MPSAFE TTY layer to the FreeBSD operating system.
The last half year I've been working on a replacement TTY layer for the
FreeBSD kernel. The new TTY layer was designed to improve the following:

- Improved driver model:

  The old TTY layer has a driver model that is not abstract enough to
  make it friendly to use. A good example is the output path, where the
  device drivers directly access the output buffers. This means that an
  in-kernel PPP implementation must always convert network buffers into
  TTY buffers.

  If a PPP implementation would be built on top of the new TTY layer
  (still needs a hooks layer, though), it would allow the PPP
  implementation to directly hand the data to the TTY driver.

- Improved hotplugging:

  With the old TTY layer, it isn't entirely safe to destroy TTY's from
  the system. This implementation has a two-step destructing design,
  where the driver first abandons the TTY. After all threads have left
  the TTY, the TTY layer calls a routine in the driver, which can be
  used to free resources (unit numbers, etc).

  The pts(4) driver also implements this feature, which means
  posix_openpt() will now return PTY's that are created on the fly.

- Improved performance:

  One of the major improvements is the per-TTY mutex, which is expected
  to improve scalability when compared to the old Giant locking.
  Another change is the unbuffered copying to userspace, which is both
  used on TTY device nodes and PTY masters.

Upgrading should be quite straightforward. Unlike previous versions,
existing kernel configuration files do not need to be changed, except
when they reference device drivers that are listed in UPDATING.

9f7b7e45d1 - Document the fact that we now use pam_passwdqc(8) to check
password quality, not login.conf(5).
- Move warnexpire and warnpasswd from the ``Accounting Limits''
  section to ``Authentication'', and nix everything else in the
  former section.  The accounting knobs are not available in
  the base system, and the subset of them available in ports
  should be documented in the ports' manpages.

22524ffbb2 Although the 'bool' type is referenced in the list of capabilities, it
is not defined in the capability type list.  Provide a definition for
'bool', if a slightly less than elegant one.  Note that this definition
does not include the complete scope of available behavior defined
in cgetcap(3), and could probably be improved.
