f29f3873ea Add a collector for ZFS, currently focussed on ARC stats. 
It is tested on FreeBSD 10.2-RELEASE and Linux (ZFS on Linux 0.6.5.4).

On FreeBSD, Solaris, etc. ZFS metrics are exposed through sysctls.
ZFS on Linux exposes the same metrics through procfs `/proc/spl/...`.

In addition to sysctl metrics, 'computed metrics' are exposed by
the collector, which are based on several sysctl values.
There is some conditional logic involved in computing these metrics
which cannot be easily mapped to PromQL.

Not all 92 ARC sysctls are exposed right now but this can be changed
with one additional LOC each.

ad2eb4a788 Use Gauge for megacli counters 
Without refactoring this to use const metrics, we need to make this a
gauge to we can keep using Set() which was deprecated for counters.

38c5890428 Reuse devinfo struct 
The devstat API expects us to reuse one devinfo for many invocations of
devstat_getstats. In particular, it allocates and resizes memory
referenced by devinfo.

ea55d0f5cb Don't race in FreeBSD devstat collector 
Querying the number of devices separately from the device list itself is
racy. Devices may be added or removed between the two calls; and removed
devices would lead to a segfault.

20ca0f1376 Eliminate memory leak in FreeBSD devstat collector 
The memory allocated by calloc was never freed. Since the devinfo struct
never leaves the function, anyway, we might as well just allocate it on
the stack.

d2fbeeb3c3 Added loadavg collector for solaris 
It seems solaris prefers "sys/loadavg.h" over "stdlib.h" when
fetching the load average.

For Illumos based OSes it was required to include "sys/time.h" to
ensure that "hrtime_t" was defined.

https://www.illumos.org/issues/6002

It also required setting the ldflags "-fno-stack-protector -lssp" to
avoid undefined symbols when linking with gcc.

/opt/local/go/pkg/tool/solaris_amd64/link: running gcc failed: exit status 1
Undefined                       first referenced
 symbol                             in file

2983c4a31d Refactor meminfo collector similar to filesystem 
Instead of doing the whole metric exposition in a platform specific collector
implementation, this creates and updates the metrics in meminfo.go and
expected a platform specific implementation of getMemInfo on
*meminfoCollector.

d2a43f7d05 Implement meminfo on BSD without cgo 
This removes some error handling, which should be fine. If the calls
fail, we will get the zeroes, which is a safe enough fallback.
Additionally, if the first sysctl (page_size) succeeded it is unlikely
that other ones will fail.
