* Two new states will be added to the tcpstat collector called rx_queued_bytes and tx_queued_bytes.
For UDP datagrams an additional collector 'udp_queues' can be used to expose the total lengths of the tx_queue and rx_queue.
@SuperQ and @discordianfish this changes gives us the option to check for overloaded UDP + TCP processing.
The names of the new TCP states and the UDP metric can be discussed.
The current reasons are just:
I don't want to add another collector for the same exposed file, so I just added the new states to the tcpstat collector.
I chose the name 'udp_queue' instead of 'udpstat' as UDP has no state.

This change maintains the current behavior as default, but also allows
the user to specify a range of CPUids to use instead.
The CPU id is stored as the value of a map keyed on the profiler

Previously, the node_textfile_mtime_seconds metric was based on the
Fileinfo.ModTime() of the ioutil.ReadDir() return value. This is based
on lstat() and therefore has unintended consequences for symlinks
(modification time of the symlink instead of the symlink target is
returned). It is also racy as the lstat() is performed before reading
the file.
This commit changes the node_textfile_mtime_seconds metric to be based
on a fresh Stat() call on the open file. This eliminates the race and
works as expected for symlinks. Fixes#1324.

With a bond interface the state of the slave interface from the bond's
point of view is reflected in `mii_status` and is independent of the
link's `operstate`.
When a bond is monitored with `miimon`, `mii_status` will reflect the
state of the physical link as configured via the operator.
When a bond is monitored via `arp_interval` the `mii_status` will
reflect the results of the bond ARP checking. This means the link can
be down from the bond's point of view, but up from a physical
connection point of view.
If a bond is not monitored via miimon or arp, the `mii_status` should
likely be always `up`, however I have observed a case where this is not
true and the `operstate` is `up` while `mii_status` is `down`. Kernel
bond documentation stresses that a bond should not be configured without
one of `mii_mon` or `arp_interval` configured however.
This change results in the metric 'node_bonding_active' matching the
up/down state of the bond's point of view rather than operstate.

* netclass_linux: remove varying labels from the 'up' metric

Starting with (not yet released) OpenBSD 6.4, sysctl KERN_CPTIME2 will
return ENODEV for offline CPUs.
SMT siblings are reported as offline when hw.smt is disabled, which is
the default since one of the later Spectre variants. So this might
affect a few systems.

While the statfs(2) approach is reliable for normally mounted filesystems, the
flags returned can be inconsistent when filesystem has been remounted read-only
after encountering an error. The returned flags do accurately represent the
internal state of the filesystem, but they do not reflect whether the VFS layer
will accept writes. Instead, it makes sense to parse the current VFS mount
state from the options field in /proc/mounts since it takes precedence.

Added a type conversion to cpu temperature sysctl. Will still

not.
Some drivers will report -1 for cpu temperature. Other sensors will
report "an input into the fan control algorithm", i.e. not the actual
temperature, but how much fan it wants. Some people cool their machines
with liquid nitrogen.

* cpu: Add a 2nd label 'package' to metric node_cpu_core_throttles_total
This commit fixes the node_cpu_core_throttles_total metrics on
multi-socket systems as the core_ids are the same for each package.
I.e. we need to count them seperately.
Rename the node_package_throttles_total metric label `node` to `package`.
Reorganize the sys.ttar archive and use the same symlinks as the Linux
kernel. Also, the new fixtures now use a dual-socket dual-core cpu w/o
HT/SMT (node0: cpu0+1, node1: cpu2+3) as well as processor-less
(memory-only) NUMA node 'node2' (this is a very rare case).
