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.

write_prometheus plugin: Optimize metric_family_get_metric().
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%.

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

Adding a call to `sort`, with the locale forced, fixes this issue.

common.c: Use _LINUX_CAPABILITY_VERSION_3 in cap_header
While check_capability() function already requires
_LINUX_CAPABILITY_VERSION_3 via "#ifdef" since commit 448627953c we still
set the cap_header's version to deprecated _LINUX_CAPABILITY_VERSION. This
results in a warning like
> capability: warning: `collectd' uses 32-bit capabilities (legacy support in use)
from the kernel when a plugin (like iptables) calls our check_capability()
function.
With this commit we will set cap_header to kernel's current capability
version (_LINUX_CAPABILITY_VERSION_3), which is default since
kernel 2.6.26.

processes plugin: Fix counters initialization / spikes
processes plugin generates spikes on (re)start. That is caused by
wrong counter logic: When collectd (re)started, monitored processes,
which was started before collectd, have non-zero values in
cpu_user/cpu_system/vmem_minflt/vmem_majflt, so `want_init` is false.
What produces spike.
At other hand, processes which are started between read cycles, should
be fully accounted without initialization. So, we must skip only first
cycle for these counters.

Fields cpu_user, cpu_system, vmem_minflt, vmem_majflt are always equal to zero for new entries (which are passed to ps_list_add()).
Values of these fields are not used in `procstat_t` entries too. So, that can be safely removed.
