Having this enabled makes collectd's stdout and stderr very noisy. From
now on, only activate this flag when collectd is built with
--enable-debug.
Thanks to Eric Sandeen for mentioning this problem on IRC.

Fix the addres of the Free Software Foundation
Provide a unified signature for ps_get_cmdline.
Prior to this change, ps_get_cmdline had different signatures for
KERNEL_LINUX vs. KERNEL_SOLARIS. This means that callers who want to
call this function would have to have an #if..#else that controlled which
variant of the function to call.
By giving them the same signature, callers don't have to worry about
that.

The field 're' only exists if HAVE_REGEX_H is defined (see definition at
line 194). So, consistent with all other usages, this should be protected
with an #if guard.

df: remove legacy code skipping "rootfs" monitoring
3512bb1 added code to skip duplicate reporting of `rootfs` mounted on `/`.
f9c1c5b and f0398d0 added generic code to skip any volume mounted twice.
Depending on the order of the entries in `/etc/mtab`, reporting for `/` was
entirely skipped.
This patch basically reverts the first, non-generic patch, as it's
superseded by the 2 others.
Fixes #1402

docs: Add info about mode7 requirement for ntpd
Since ntpd-4.2.7p230 "mode 7" requests are ignored by default, and
that's what ntpd plugin uses currently. The ntp daemon must be
explicitly configured to enable mode7 requests.
This patch adds short information about that to collectd.conf manpage.

docs: mention regexps for the interface plugin
It is very useful to collect data (or ignore) from a group of interfaces
that are similarly named - especially if the list is dynamic and it's
not feasible to update configuration each time an interface shows up or
disappears. It's possible to use regexps to specify interfaces to
collect data from (or ignore), but it's not clearly stated anywhere in
the documentation.
This is an attempt to improve documentation in this area.

This solves the integer overflow when passing huge latency values to
latency_counter_add(). In addition to fixing the overflow the function
will now ignore values that are larger than LLONG_MAX, i.e. the longest
possible latency is 272 years. As a nice side-effect, the precission of
latency_counter_get_percentile() is improved.
