desktop_notification: Added a plugin to send desktop notifications.
This plugin sends desktop notifications to a notification daemon, as
defined in the Desktop Notification Specification (see
http://www.galago-project.org/specs/notification/).
The timeout after which to expire the displayed notification may be
configured in collectd.conf.

Using something like

This is meant to be used in frontends which want to display up-to-date graphs
but there are too many hosts/rrd files to update them ``live'', i. e. without
caching.

The flush callbacks have been changed to expect an (optional)

daemon: Ignore SIGPIPE.
The default action for the PIPE signal is to terminate the process. This
is not really what we want for collectd, as e.g. a client of the unixsock
plugin (which might even be running without root privileges) could kill
the daemon by closing the socket right after sending a request.
The signal now gets ignored and each I/O function is checked for success.
To simply that, the unixsock's output stream is now configured to be line
buffered, removing the need to call fflush() (which could fail as well and
would have to be checked for success).
While I was at it, I renamed the sigaction struct for SIGCHLD to fit the
coding style used elsewhere in collectd.

removed it from all packages. To be able to use it, we need to take care

On FreeBSD, PERL_SYS_INIT3 expands to some expression which triggers a "value

Added "type" to the value_list_t struct.
This way, the complete tuple (host, plugin, plugin instance, type, type
instance) is stored in a single data-type which is more straight forward
and allows a more flexible use of that data-type. As a consequence, there
is no longer a need to explicitly pass the type to some functions, most
notably plugin_dispatch_values(), which have been updated in that respect.
The "perl" plugin has also been updated to reflect this change. For
backwards compatibility, plugin_dispatch_values() still accepts a second
argument - however, a warning will be submitted to the daemon in that
case.
