fixes a segfault when walking memiftable.

instead of letting hardware rings grow on every interrupt, restrict
it so it can only grow once per softclock tick. we can only punish
the rings on softclock ticks, so it make sense to only grow on
softclock tick boundaries too.
the rings are now punished after >1 lost softclock tick rather than
>2. mclgeti is now more aggressive at detecting livelock.
the rings get punished by an 8th, rather than by half.
we now allow the rings to be punished again even if the system is
already considered in livelock.
without this diff a livelocked system will have its rx ring sizes
scale up and down very rapidly, while holding the rings low for too
long. this affected throughput significantly.
discussed and tested heavily at j2k10. there are still some games
with softnet we can play, but this is a good first step.

tables and scalar values.
Fixes system/6468 by not calling table get functions with an unexpectedly
short OID.
Also fixes system/6071. Scalar variables without an instance specified now
returns a noSuchInstance error. GetNext requests correctly returns the .0
instance.
This means you can no longer rely on
$ snmpget -v2c -c public localhost SNMPv2-MIB::sysDescr
returning the .0 instance. You need to specify it explicitly:
$ snmpget -v2c -c public localhost SNMPv2-MIB::sysDescr.0
Also return proper SNMPv2 errors per varbind instead of a noSuchName error
status, unless SNMPv1 was specified in the request.
An earlier version of this diff tested by Remi Laurent, thanks.

If this happens the imsg may no longer be usable as there may be queued
messages, but this is a) already the case with the code now, and b)
would be the case if recvmsg() fails anyway, so we can document that -1
from imsg_read() invalidates the struct imsgbuf.

Make the imsg protocol network-safe.
it might be network safe, but half the imsg based daemons on my firewalls
dont run anymore.

Currently the receiver fetches an imsg via imsg_get() and if he expects
an fd, he then calls imsg_get_fd() to fetch the next fd queued on the
imsgbuf from which the imsg came.
This changes hides the fd queueing mechanism to the API user. When closing
an imsg with an fd, the message is flagged so that the receiving end knows
it must dequeue the fd in imsg_get() and return it with the imsg structure.
This way there is no (less) possible screw up from imsg_get_fd() not being
called directly after imsg_get() by the user. The retreived imsg is
self-contained.
