These two memory classes have been here for a while now in FreeBSD,
adding them allows having information for all memory classes.

Log a single error message when the udev data directory (`/run/udev/data` by
default) is unreadable, and then don't try to get device properties out of it.
Also lower the log level from error to debug when we can't parse the udev files
properly, since these messages would be sent every time the node exporter gets
scraped.

When parsing udev data, skip lines that don't start with `E:`.
Lines prefixed with `E:` represent device properties, as documented in
udevadm(8).

Set the `--path.udev.data` flag to point to the udev fixture, and update the
output fixture with
```console
$ ./end-to-end-test.sh -u
```

Now that we read some data from `/run/udev/data`, add the corresponding
fixtures and update the expected test results accordingly.

Instead of hard-coding the path to `/run/udev/data`, intoduce a
`--path.udev.data` flag that defaults to that value.

Add labels to the `node_disk_info` metric extracted from udev, such as `model`,
`path`, `revision`, `serial` and `wwn`.
Also add a few metrics related to filesystem and device mapper, which are also
extracted from udev information.

Fix up handling of CPU info collector on non-x86_64 systems due to
fixtures containing `/proc/cpuinfo` from x86_64.
* Update e2e 64k page test fixture from an arm64 system.
* Enable ARM testing in CircleCI.
Fixes: https://github.com/prometheus/node_exporter/issues/1959

* Correctly name collector file.
* Fix cgroup summary type as gauge.
* Use a boolean metric rather than a label for enabled.

Use unix.ByteSliceToString to convert Utsname []byte fields to strings.
This also allows to drop the bytesToString helper which serves the same
purpose and matches ByteSliceToString's implementation.

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.
