riemann plugin: Fix a double-free issue with the shared structure.
The reference to the riemann_host structure is shared between the write
and the notification callback. Upon exit, riemann_free() is called twice,
via the user_data_t structure passed to the register functions. Previously
this would have caused a double-free, which is unacceptable.
This patch introduces a reference counter and will only free the structure
(and close the socket) when the last reference is freed.
The locking has been moved out of the riemann_connect() function and into
the riemann_send() function. It is unlikely, but not impossible that two
threads interfere with each other when writing to the socket.

riemann plugin: Add support for service names.
I.e. you can not define a "riemann" service in /etc/services and then use
«Port "riemann"» in the configuration. Also add support for arbitrarily
long host names.
First implementation of a riemann plugin.
This is basic for now and only support
sending to a UDP target, later work will
include notification support and service
rewriting.

config: Implemented include filter pattern as sub-option in a <Include> block.
This has the advantage of being more easy to read/understand and also being
more flexible. E.g. multiple filters and other options may be specified in the
future.

config: Added support for specifying include filter patterns.
An optional second argument may now be passed to the "Include" configuration
option. If specified (and if the fnmatch() function was available at build
time), only files matching this pattern will be included. For example, the
following will include all files matching "*.conf" in any subdirectory of
/etc/collectd.d/:
Include "/etc/collectd.d" "*.conf"
This is useful, e.g. for distributions in order to include a possibly empty
directory in the default configuration including all subdirectories but also
making it possible to ship further documents like README files.

The name generated by the Aggregation plugin currently includes the

clever there I guess.

postgresql plugin: Simplified transaction handling a bit.
Don't set any next commit time after committing a transaction but only when
starting a new transaction. This way, db->next_commit == 0 always means that
we're outside of a transaction. Also, this removes the need to restart a
transaction right away. Rather, the write callback will take care of that the
next time it gets any data.

postgresql plugin: Unregister all writers on shutdown.
This will make sure that all pending transactions will be committed. Else, the
open transactions would be rolled back by the PostgreSQL backend when closing
the connection.
In order to do so, all database connections are now stored in a plugin-global
array (this will also make further changes possible). Also, a ref-count has
been added to the database object in order to support "deleting" an object
twice when having it in use by a connection doing queries and writes.
If specified, this option causes a writer to put several updates into a single
transaction. This transaction will last for the specified amount of time (in
seconds). By default, each update would be executed in a separate transaction
causing quite some overhead.

They made sense when all data was collected at the same interval. This

We could transform them into a per-VL check and use complaints to notify

ping plugin: Don't abort the "ping_thread" when ping_send() fails.
This may happen when the network is down. If the thread fails, the read
callback will indicate an error and the exponential back-off will start.
This is not optimal for this scenario, since you usually want to have
ping stats from right when the network is back up.

aggregation plugin: Implement the "GroupBy" option.
This new configuration format has two benefits:
1) It is easier to understand by users, because they don't have to know
about two types of wildcards.
2) In the future matching of Host, Plugin, Type, ... may support regular
expressions. In that case, this configuration syntax doesn't need to
be adapted.
