src/utils_db_query.[ch]: Add the possibility to `pick' queries by name.
src/utils_db_query.c: Add support for the `Column' configuration option.
The support has been implemented as unobtrusively as possible:
- The `udb_result_t' type now has two new members:
`legacy_mode' and `legacy_position'. The `legacy_mode' member is used
to switch to a new set of functions for handling these special
results.
- Those ``legacy results'' use only a small subset of the members in
`udb_result_t'. The different behavior has been put in the following
functions:
udb_legacy_result_finish_result
udb_legacy_result_handle_result
udb_legacy_result_prepare_result
udb_legacy_result_create
- The non-legacy counterparts to finish, handle, and prepare
automatically call the legacy version if the `legacy_mode' member is
set to `1'.
WARNING: Untested code, the PostgreSQL plugin still needs to be ported.

When passing `1' as `legacy mode' to `udb_query_create', compatibility
with the postgresql plugin in version 4.5 is enabled. This means that
the options `Query', `MinPGVersion' and `MaxPGVersion' are understood in
the <Query> blocks.
Yet to do is support for the `Column' options. The `Param' option should
probably be implemented using the already existing callback function.

Fixed various signedness issues identified by -Wextra.
The following two issues have been addressed:
* comparison between signed and unsigned - this was found in several places
throughout the code and has been fixed by switching to more appropriate
types or adding appropriate explicit casts.
* comparison of unsigned expression < 0 is always false - this was found in
the processes and vserver plugins where a size_t had wrongly been used
instead of a ssize_t and an int respectively.

Document unused parameters.
In all cases where unused parameters have to exist either because some API
requires it or for more consistency, they now have been documented using
__attribute__((unused)) (which is automatically disabled in case GCC is not
used to prevent problems with compilers not supporting attributes). In a few
other cases, the parameters have been removed.
This allows the use of -Wunused-parameter (which is enabled by -Wextra as
well, when using -Wall).

Let plugin_dispatch_values() set value_list.time in case of 'now'.
Basically any (read) plugin was calling time(NULL) to set the time of a values
list. This is now done by plugin_dispatch_values() in case the time is zero
(which is the case when using VALUE_LIST_INIT or VALUE_LIST_STATIC).
This change slightly simplifies the code and makes future changes to the time
management (like the possibly upcoming subsecond resolution support) less
intrusive in respect to the amount of required code changes.

Converted timeval_sub_timespec() to timeval_cmp().
The third (return) argument is now of type 'struct timeval' (instead of
'struct timespec') as well. Also, it may now be NULL, in which case the
difference is not returned. This is a more general and thus more flexible
approach that permitted to remove the custom timeval_sub*() implementations in
the multimeter and ntpd plugins.
The return value has been changed to reflect the return value used by
functions like strcmp(), i.e. it is less than, equal to, or greater than zero
if the first argument is less than, equal to, or greater than the second
argument respectively.
In the cases where a 'struct timespec' is required, the return value is now
converted by multiplying the tv_usec member with 1000.

The macro BAIL_OUT_CONTINUE() is used inside the loop iterating over the
result sets to clean up and continue with the next loop iteration. In two
cases this was used in a loop iterating over the instances and values lists
contained within that loop as well though. This would cause the memory that
was currently written to (the two target lists) to be freed and thus cause a
possible segfault. In any case it would leave behind inconsistent and most
probably uninitialized data. The usage of that macro has now been pulled out
of the inner loops.

This patch changes the `mutex_lock' to a `mutex_trylock' and data is only
appended to the global receive-queue if the lock can be obtained without
blocking.
If the lock cannot be obtained without blocking, the data is instead appended
to a private queue and that queue is appended to the global queue when the lock
can next be taken.
On very busy systems, the thread apparently may not be scheduled often enough.
So the receive buffer fills up quickly and data may be lost.

Merge branch 'dm/t_option'
collectd: Don't *abort* on the first read-error with the `-T' option.
The `-T' option used to basically quit the daemon right away when the
first read function of a plugin failed. This patch changes the behavior,
so that:
- All read-functions are tried. If one or more fail, the daemon will
exit with a non-zero exit status, but all read-functions will be
tried.
- Don't quit if one read-function failed without calling all the
shutdown-functions first. This will clean up the UNIX socket of the
unixsock plugin and stuff like that.

collectd: Add the -T option.
The -T switch:
- implies -f
- does not start any read threads
- invokes callback() foreach list_read and will exit 1 on failure, 0
otherwise
Makes for a nicer dryrun than -f + ^C, also makes it possible to wrap
with a test harness such as Test.pm

openvpn plugin: Added support for LZO compression.
There are four counters for pre/post (de)compression. The code compares
the pre/post counters and submits the current compression ratio based on
the counter change rate.
The type `compression_ratio' (gauge) is used to store the data.

src/common.[ch]: Add `counter_diff', a function to calculate the difference of two counters.
It's not just a simple (old - new), because wrap-around is handled, too.
