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.

postgresql plugin: Pass an array of data-source types to writers.
The array includes the stringified version of the data-source type, i.e.,
'gauge', 'counter', etc. This will enable the writer to treat different types
differently. However, when having 'StoreRates' enabled (the default) all types
will be 'gauge'. So, in most cases, this won't be used but it has been added
for completeness and to be safe for the future.

postgresql plugin: Added 'StoreRates' feature to writers.
Similar to other write plugins, this option causes counter values to be
converted to rates before submitting them to the database. The option defaults
to true.

postgresql plugin: Added generic support for writing values to a database.
This has been implemented by requiring the user to specify an SQL statement to
be used for storing a value-list in PostgreSQL. Usually, this should be done
by creating custom functions to take care of that.
The user specified statement will then be called by collectd with eight
arguments: time, host, plugin, plugin instance (or NULL), type, type instance
(or NULL), array of value names (data source names) and an array of the
values.
Two elements have been added to the config parser: A <Writer> block may be
used to name an SQL statement (specified using the 'Statement' option) to be
used for writing data. In a <Database> block, the new option 'Writer' may be
used to apply a writer to a database connection.
The current approach has two benefits: for one, a user may chose whatever
database layout best suits her needs. Also, it is very easy to experiment with
different approaches on how to structure the data in a database without the
need to modify the plugin. This can be done in SQL, which (hopefully) is the
language that people working with PostgreSQL databases like most ;-)
If it happens to turn out that some approach is rather superior, it may still
be re-implemented in a specific plugin in later versions.

network plugin: Do not forward received notifications.
The network plugin would send out all notifications it got through its
callback, even the ones it received itself and even when forwarding was
disabled.
With this patch the network plugin will only transmit notifications created
locally -- forwarding of notifications is not implemented due to missing
loop-detection. For loop-detection we would have to keep track of the last
timestamp of each notifications, and since each host/plugin/type/-instance
field may be empty, this is not as straight forward as with value lists. If
someone needs this, they will need to invest some work I'm afraid.

Proposal fix for large "MaxPacketSize" use.
When we use a "MaxPacketSize" over two thousand of octets (to pass huge
message in notification for example), buffer may not be flushed for a
while.
By flushing buffer when there is about 1400 octets, we're sure there is
no data too longer in.

nfs plugin: Remove duplicated code.
Changes include:
* Calculate nfs[234]_procedures_names_num at compile time.
* Made nfs_procedures_submit() more versatile, so it can be used from the Linux
and the Solaris code.
* Switched to plugin_dispatch_values_secure(), since the code is using the same
value_list_t for multiple values.
* Broke out nfs_submit_fields() from the Linux code. This removed quite a bit
of code duplication between the v2/v3 code.
* Broke out nfs_read_kstat() which does the get_kstat_value() call in a loop
rather than duplicating all the NFS procedure names.

collectd-5.0.1-mine.patch some processes.c fixes for FreeBSD

Our thoughts are now occupied by Putin and vodka, however...
I have paid attention to a little incorrect data which is given out by
a processes plugin on my beautifull FreeBSD system.
I have corrected them and in process have made absolutely slightly
have improved accuracy and productivity of a processes plugin for
FreeBSD systems.
- Fix strange plural call of getpagesize(). Has entered a global
variable and initialization procedure for FreeBSD
- Data was summarized on all processes including threads. It led to
absolutely uncertain result. Fix based on codebase of FreeBSD top
programm. KERN_PROC_ALL attribute keep for future purposes.
- Gets command argument failed for some processes as system and some
other. It led to error messages to console. Fix based on codebase of
FreeBSD top programm.
- System and user CPU times turned out from the sum of miliseconds
and... Oh! microseconds in one glass with overflow possibility. Fixed.
My girlfriend has left me for such Christmas vacation, but I am
assured that have made good business.
