value match: Add a match to check the actual value(s) of data-sources.
src/filter_chain.[ch]: Implement the built-in `return' target.
The `stop' target now aborts all processing of the value completely, `return'
only stops the current chain and continues processing the parent chain.

collectd.conf(5): Document the regex match and the set target.
regex match: Require *all* regular expressions to match.
Before, when there were multiple regular expressions for the same field,
for example the host, only of of those regular expressions needed to
match for a successful overall match.
The new behavior is not that *all* regular expressions need to match for
a successful overall match. This makes the behavior much easier to
understand.

It's currently possible to re-set the `type'. This is most likely not
good and will result in unpredictable behavior. I'll remove that,
probably.

src/meta_data.[ch]: Added a framework for meta data.
This framework is planned to be used in at least three places:
- Extend the global cache to allow attaching a meta-data object to each
entry. The meta-data can then be used by other plugins to attach
miscellaneous information to an entry. Possibly uses include
calculation of floating averages or storing the state for a hysteresis
threshold.
- Add a meta-data object to every `value_list_t' in
`plugin_dispatch_values'. The meta-data object can then be used by
matches and targets to pass information about a value-list to one
another.
- Replace the notification meta-data stuff in src/plugin.[ch] with such
an object.

The match_regex now registeres a match with the new infrastructure and uses
regular expressions to match certain values based on their identifier.

src/plugin.[ch]: Added support for "filter" callbacks.
This type of callback is very similar to write callbacks:
int (*) (const data_set_t *, value_list_t *)
The return value of that callback indicates what further actions are to be
taken. It may be a bitwise OR of any of the following new flags:
FILTER_NOWRITE or FILTER_NOTHRESHOLD_CHECK. If both flags are used (which
equals the flag FILTER_IGNORE), the value list is ignored completely.
If more than one such callback is available, the respective return values are
bitwise OR'ed. If they "sum" up to FILTER_IGNORE, no further callbacks are
executed (lazy evaluation).
This type of callback may be used for the following purposes:
* rewrite information included in the value list (e.g. the instance
name)
* discard certain information on a fine-grained level based on the
information provided by the data set and value list
