postgresql_default.conf: Make sure the "disk_io" query does not return NULLs.
Starting with some version between 8.3.3 and 8.3.6, pg_statio_*_tables returns
NULL instead of 0 for statistics if no instance of the appropriate relation
exists. PQgetvalue() returns an empty string in that case which would then
result in error messages when udb_result_submit() tries to convert that to a
number.
Now, the "disk_io" query uses PostgreSQL's coalesce() function to make sure 0

behavior, too.

resulted in a different behavior, but still crashing the daemon. We'll

src/common.c: Fixed a race condition in check_create_dir().
Between checking for the existence of a directory using stat() and creating
the directory using mkdir(), another thread might have already created the
directory thus causing mkdir() to fail with errno == EEXIST. This case is now
handled sanely, no longer causing the function (and thus some write callback)
to fail in this case.
Most likely, this only happens during startup when creating the data
directories - later, no two threads should try to create the same directory.
Interestingly enough, I frequently encountered this issue on a single core
machine.

src/plugin.c: Assure that targets get dynamically allocated memory.
If targets want to replace the values, they will have to use dynamically
allocated memory. If they can't free the values, because the pointer
might point to statically allocated memory, memory will be lost.
Unfortunately stack allocation will not do, since we will then not be able
to detect multiple replacements.
To impose as little a performance issue as possible, the dynamic allo-
cation is only done when either chain is present. If the filter mecha-
nism is not used, the values will not be copied.

java plugin: Add support for `match' callbacks.
Holy crap, that one needed some serious magic.. The problem is, that the
filter chains are created before the initialization functions are run.
Since the Java plugin used to initialize the JVM and load the classes in
the init function, the match callbacks were not available in time.
The behavior is now: Create the JVM as soon as the the first `LoadPlugin'
option is found and load and configure all Java plugins while in the
configuration phase. (I. e. exactly like C plugins.)
Phew, I've earned that beer now.

src/plugin.[ch]: Implement `plugin_dispatch_values_async'.
This function differs from `plugin_dispatch_values' in that it will add
the value_list_t to a queue rather than calling the write functions
right away. This as at least two advantages:
- The _async function will often return faster, since no file
operation is done.
- The ``read thread'' and the ``write thread'' are not the same
thread. This makes it much easier for plugins that provide both,
`read' and `write' callbacks.
