This is necessary to build on darwin using nix, as nix-darwin uses an
older macOS SDK, built from Apple's open source releases.

In certain instances on heavily loaded nodes with many network
devices, there may be concurrent access to the netdev collector's
`metricDescs` map, resulting in a panic. This adds a mutex to prevent
concurrent reads and writes to the map.

Move the systemd version function to an exporter method. This way we can
update the Verison information at every scrape, in case the underlying
version changes.

systemd patch versions are as important as the major version number;
they indicate security or bug fixes or other behavioural changes between
versions.
Use float64 over float32 as the rounding error with float32 rendered
250.3 as 250.3000030517578 in my testing.

analogous to the /var/lib/docker exclude added in
https://github.com/prometheus/node_exporter/pull/814
podman rootful containers mount eg. shm filesystems at
/var/lib/containers/storage/*-containers/*/userdata/shm. these should be
treated like things under /var/lib/docker by default.

This adds a new Linux metric, node_softirqs_total, which corresponds
to the 'softirq' line in /proc/stat. This metric is disabled by
default and it can be enabled with '--collector.stat.softirq'.

TCP timeouts count is a useful signal to show
abnormal network performance and is another
signal to aid debugging. This metric can be
used to generate proactive alerts for host
network namespace workloads.

The new `lnstat` collector produces a high number of metrics, per-cpu,
and results in approximately double the number of metrics previously
scraped. For example, a typical server with 64 cores produces 3832
lnstat metrics compared to 4147 metrics for the remaining collectors.
Therefore disable the `lnstat` collector by default.

Sanitizing the metric names can lead to duplicate metric names:
```
caller=level.go:63 level=error caller="error gathering metrics: [from Gatherer #2] collected metric \"node_ethtool_giant_hdr\" { label:<name:\"device\" value:\"ens192\" > untyped:<value:0" msg=" > } was collected before with the same name and label values"
```
Generate a map from the sanitized metric names to the metric names from
ethtool. In case of duplicate sanitized metric names drop both metrics,
because it is unknown which one to take.
