Fix the inheritance of the FBSDprivate_1.0 namespace.

Move _b functions into the 11.x symbol version namespace.

Add a FBSD_1.3 namespace for FreeBSD 10.

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

Add the FBSD_1.2 namespace.

Bump our namespace version for 9.0.

Add a comment about keeping the private namespace at the end of
the dependency chain.

- Import the HEAD csup code which is the basis for the cvsmode work.

Keep versions on a dependency chain to exclude even remote possiblity
of private version ever getting index 2.

Add a comment stating not to bump the FBSDprivate version.

Don't inherit the public namespace from the private namespace.

Retire the __fgetcookie(), __fgetpendout(), and __fsetfileno() accessors
as we aren't hiding FILE's internals anymore.

Add __fgetcookie(), __fgetpendout() and __fsetfileno() to the private
name space.

Increment the version namespace for 8.0-current. New symbols and
symbols whose ABI has changed should be added to FBSD_1.1.

Make sure FBSDprivate_1.0 is located at the end of the version
inheritance chain.

Number the private version namespace in case we ever want to have
compatibility between versions (as we do for the public namespace).

Add symbol maps and initial symbol version definitions to libc.
