bsnmpd: Only refresh devtree if devd event is a new or removed device.

It makes sense to refresh the tree only when a device is inserted or
removed, otherwise bsnmpd wastes lot of CPU.

Use full buffer size in read(2) call, there is no need to preserve the
last byte of the buffer.

Since we call refresh_device_tbl() for any devctl event types - no need
to check the first byte of buffer. Remove these checks.

Also remove logging for the case of unknown devd message. It incorrectly
triggers when all devctl events are not fit into one buffer and part of
unread data will be read in the next pass.

When length of data readed from devctl is equal to sizeof(buf), then try
to read from socket again, to read full data.

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.

Collapse devinfo_state_t with device_state_t in order to avoid a
structure replication and improve manteneability.

Reduce the memory requirements for the tables by (1) using malloced strings
instead of maximum sized arrays embedded in the table structures and (2)
using pointers to constant oids instead of copying the oid into each
table structure. This also fixes indexing in the case when a string used
for indexing is longer than the maximum size allowed in the MIB.
