The reasoning behind this, is that if we are consistent in our
documentation about the uint*_t stuff, people will be less tempted to
write new code that uses the non-standard types.
I am not going to bump the man page dates, as these changes can be
considered style nits. The meaning of the man pages is unaffected.

It's too late to change this in 9.0 -- so we have a release with the
misspelling in the wild and should not break users that depend on it.
Deprecating/replacing it because of a one-char typo seems excessive.
In this contest, index refers to the index(3) function. In this case it
doesn't really harm, as this function is never called with idx == NULL.

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.

- Sample CPU usage data from kern.cp_times, this makes for a far more
accurate and scheduler independent algorithm.
- Rip out the process list scraping that is no longer required.
- Don't update CPU usage sampling on every request, but every 15s
instead. This makes it impossible for an attacker to hide the CPU load
by triggering 4 samplings in short succession when the system is idle.
- After reaching the steady-state, the system will always report the
average CPU load of the last 60 sampled seconds.
- Untangling of call graph.

I'm unsure if some MIB standard states this must be the load average
for, eg. 300s, it looks like net-snmp isn't even bothering to implement
the CPU load reporting at all.
and modify the BEGEMOT-PF-MIB to add support for IPV6 address' statistics in the PF
tables via pfTablesAddrNetType and pfTablesAddrNet. While here, upgrade the
pf_tree.def file to the new format that includes enumerated values. Also make sure
to return SNMP_ERR_NOSUCHNAME for ALTQ objects, if ALTQ is disabled, so that the agent
will know to skip the pfAltq subtree when servicing GETNEXT requests from SNMP clients
(otherwise snmpwalk on begemotPf would stop at the pfAltq subtree with bsnmpd returning
SNMP_ERR_GENERR).
then find a specific entry, and get the requested value. So far, it found
the specific entry, refreshed the entry list if necessary, and got the
requested value from the found entry. The problem is that refreshing nukes
all old entries and replaces them with new ones and the obtained entry
pointer was no longer valid after the refresh.

It is possible for the kernel to return the queues not by pa.altq.qid order.
When this happens, pf_snmp would only partially fill its table.

* Adopt to new API.
* In bridge_attach_newif() remove an additional pointer to the buffer

- Adopt to the new API.
- Change check for error code of getifaddrs().
- First check for sa_family != AF_LINK.
- Copy sockaddr_dl * to get around alignment constraints on some

- Use strcmp instead of strncmp so that "foo11" != "foo1".
* other functions:
- Allocate n times of the struct we need instead of arbitrary len,
cast to the type we want it to be and pass around struct *s instead
of char *s. This gets us around alignment restrictions on some
platforms and in addition it is more clear what data is passed around.
- Name variables for same types consistently.
