Similar to r311750, check for the result from smiGetModule to avoid a segfault
when dereferencing a NULL pointer later on.

Choose to just check for the NULL pointer in the next for-loop for now to fix
the issue with a minimal amount of code churn

sys/queue.h use here would make more sense than using a static table

Check result from smiGetFirstNode and smiGetNodeByOID

This avoids a segfault with malformed or unanticipated files,
like IPV6-TC.txt (a file containing just TEXTUAL-CONVENTIONS).

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

(S)LIST_HEAD_INITIALIZER takes a (S)LIST_HEAD as an argument.
Fix some wrong usages.
Note: this does not affect generated binaries as this argument is not used.

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.

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

Vendor patch: add support for the BITS construct and enumerations in both
gensnmpdef and gensnmptree. Add include and typedef directives to gensnmptree.
