configure.ac: fix path when testing for liboconfig/parser.c presence
processes: use long for pids on linux and solaris
Up to now, we had a mix of `int`, `long` and `pid_t` to represent the
variable part of `/proc/<PID>/status` and friends. This patch
standardizes on `long` on the Linux and Solaris platforms.
The max size of `int` is smaller than the maximum number of processes
current kernels support. `pid_t` is used to ensure portability of
functions such as `getpid()`, which aren't used in this plugin, and
apparently resolves to an `int` on Solaris.
This is a follow up to bb978c1, which triggered a format string issue on
solaris 64 bit.

We use some bison-specific extensions so we really need bison, not yacc.
This has bitten a few people before, so make it easier for them.
Bison is only needed when compiling from git, since we ship the generated file
in the tarball. We take this into account by checking for the generated file first.

turbostat: fix whitespaces in log messages
Don't divide by 0 when doing percentages (e.g. with the swap plugin).
Prior to this change, if all the values being sent sum to zero, then the
calculated percentage is a division by 0 which is either Inf or NaN
depending on the numerator.
This is not a theoretical concern: it can easily happen if all the input
gauges are 0.
This change forces the output to be zero if the denominator is zero.

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.

df: remove legacy code skipping "rootfs" monitoring

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

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 solves the integer overflow when passing huge latency values to
