tail plugin: Rename DSType from Latency to Distribution.
This is a more flexible naming owing to the fact that percentiles and other
distribution parameters are interesting for a variety of metrics, not just
latencies.
The config handling is now completely in src/utils_latency_config.c so
that other plugins, such as the cURL plugin, can easily reuse the module
with consistent config handling.

src/utils_latency.[ch]: get_rate(): Make lower bound exclusive.
This has a bunch of benefits:
* You can easily iterate over a range of latencies without counting
latencies twice. This was previously tricky because both borders were
considered to be inclusive.
* When lower equals upper, the returned value is now zero.
Previously, it was a value very close to zero, but not zero. The exact
value depended on the bucket width, an information not easily
available to the caller.

Rewrite the check for libdpdk
This fixes various issues, like us not picking up the right include path
and testing for the library in the wrong location.
We now allow you to override the CPPFLAGS and LDFLAGS by doing
./configure LIBDPDK_CPPFLAGS="-I/path/to/your/libdpdk_headers" LIBDPDK_LDFLAGS="-L/path/to/your/libdpdk.so -Wl,--no-as-needed"
The nice thing is that these settings are now logged and remembered
between configure runs.

write_prometheus plugin: Improve performance of metric_cmp().
This function is a hotspot because it is used by bsearch() to look up
metrics in a metric family. This simple (though non-obvious) change
brings prom_write() complexity down from 3000 instructions/call to 2640
instructions/call, i.e. a 12% improvement.
Profiling showed that prom_write() spent 73% of its time in this
function. 36% of time was spent in metric_create() and 19% was spent in
metric_destroy().
This patch replaces these two calls by a stack allocation, reducing the
time prom_write() spends in metric_family_get_metric() to 42%.

collectd-tg: Fix sleep interval.
nanosleep() was called with the current time, meaning that it would

configure.ac: make finding java deterministic
The sort order of the `find` command proves to be dependent on external
factors, which makes `./configure` pick different java versions on
different systems, making the whole build non-reproducible (see
https://reproducible-builds.org/ for more details).
Adding a call to `sort`, with the locale forced, fixes this issue.
