bind plugin: Actually handle RR cache numbers as `gauge'..
Hi Florian,
Well a working patch was even less trivial as the quick one from
yesterday evening.
Just using a gauge type is not sufficient (only 0 is written to RRD
files), it's also necessary to adjust the bind_xml_stats_handle_view()
as has been done for the memory statistics
Attached is a patch to bind.c (I skipped types.db) which fixes the
cache data collection.
In addition I attached a graph of the cache evolution and memory (for
memory it might be worth giving it an own type as it's not cumulative
at all)

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

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.

A few bugs are hidden there, attached is a patch that fixes most
of those I've discovered untils now.
- Url parameter never considered
- missing type definition for dns_reject
- MemoryStats is linked to the wrong variable
(TODO: memory stats seem not to work, probably dispatch_counter()
for gauge value ...)
- SOAOutv6 should be translated to SOA-IPv6 instead of SOA-IPv4
in order to be saved correctly and not cause timestamp collisions
