powerdns plugin: Added a plugin to read statistics from PowerDNS' control socket.
disk plugin: Implement an ignorelist.
Not all disks collected by the disk plugin may be of interest. This commit
implements an ignorelist as provided by src/utils_ignorelist.c to make it
possible to select exactly which instances are interesting and which are not.

src/utils_ignorelist.c: ignorelist_match: Allow the `ignorelist' to be NULL.
This makes calling the function easier, because initialization of the
ignorelist in the plugin usually depends on configuration parameters..

unixsock plugin: Open two different IO stream handles for reading and writing.
Full-duplex standard IO streams are not really supported on sockets.
Mixing input and output functions involves calls to lseek(2) which is
not supported on sockets and thus causes the IO operations to fail.
Opening two IO streams solves the problem.

Disambiguated the protocol used by the unixsock (and other) plugins.
As discussed with Florian on IRC, the interpretation of the status line
returned by the unixsock plugin (et.al.) is now strictly specified. A status
greater than or equal to zero indicates success and the number of subsequent
lines of output. A negative status still indicates failure.
This way, frontends can manage the output without having to know any
command-specific interpretation rules.
The GETVAL command has been updated to implement this specification. It now
returns each value on a separate line. collectd-unixsock(5) has been updated
to reflect the changes.

unixsock plugin: Use `src/utils_cmd_listval.[ch]' and remove the local cache.
Since no command uses the cache in the unixsock plugin anymore, it can be
removed. The implementation in `src/utils_cache.[ch]' is now used for all
commands, and all commands are in separate modules. This should be a
performance gain, since the implementation of unixsock used a linked list,
which is much slower than the AVL tree used in the global cache.
Also this resolves a nasty bug: The unixsock plugin used to use the _local_
interval setting when removing values from the cache. The global cache uses the
interval setting of the values themselves, to that mixing different intervals
in a big setup is now compatible with the `listval' and other commands.

network plugin: Align write access to the send buffer.
SPARC and possibly other architectures cannot access arbitrary memory
locations. This caused a `bus error' on SPARC when the network plugin was
loaded. This change hopefully fixes this problem.

src/Makefile.am: Added dependencies on `utils_cmd_putnotif.[ch]' to the exec plugin.
src/utils_cmd_{putnotif,putval}.h: Don't include `plugin.h' without a reason.
src/utils_cmd_getval.[ch]: Moved the `getval' command out of the unixsock plugin.

unixsock plugin: us_handle_getval: Changed the function to use the global cache rather than the local one.
src/utils_cache.[ch]: Implemented `uc_get_rate_by_name'.
This functions allows to get values from the cache without creating a
`value_list_t' and `data_set_t' first. The existing function `uc_get_rate' has
been changed to use this function, too.

collectd, plugin: Added support for "flush" callbacks.
A flush callback may be provided to make it possible to flush internal caches
(e.g. the rrdtool plugin's data cache) from outside the plugin. On SIGUSR1,
flush callback is invoked for all plugins. As flushing large amounts of data
might take some time a new thread is started to handle the request
asynchronously.
Thanks to Stefan Völkel for proposing this.
