Fixed some compiler warnings identified by gcc's -Wextra option.
The following issues have been addressed:
* comparison between signed and unsigned - this was found in several places
throughout the code and has been fixed in various ways
* missing initializer - an incomplete initializer has been used for two
struct instances in perl.c
* unused parameter - when applicable, the parameter has been removed; in
thirteen cases the parameter is required by different library API's and in
two cases the parameter was left in place to retain a consistent interface
within the affected modules; as __attribute__((unused)) is a GNU extension,
it has not been used to document those exceptions

It's only what I had in mind right now and not a complete list.
collectd-exec(5): Documented the changes due to notifications and the Nagios plugin support.
Added support for more than one TypesDB file.
The "TypesDB" config option now accepts more than one filename. Each file will
be read in the specified order. If no filename has been given, the default
file will _not_ be read (I doubt this is a useful feature but it's imho the
most reasonable behavior).
This may, for example, be used to specify an additional file containing custom
data-set definitions. See the thread "Thought about exec and types.db" on the
mailing-list ([1]).

src/configfile.c: Updated the copyright notice for 2008.
libvirt plugin: Updated the copyright notice for 2008.
libvirt plugin: Fix the HostnameFormat option.
The attached patch fixes HostnameFormat in libvirt driver.
The intended use for this was:
HostnameFormat "name"
generating hostnames like "<guestname>" (the default case), and:
HostnameFormat "hostname name"
generating hostnames like "<hostname>:<guestname>".
Somewhere along the way, however, that code got broken so it always adds a ":"
before the name, and doesn't concatenate any more, so you'd get weird hostnames
appearing like ":guest" which was supposed to be "hostname:guest".
The patch just reverts back to my original code.

sensors plugin: While I was at it I reorganized the code a little so it's easier to read.
For instance I moved the name to type conversion out of the main loop and into

`submit' function is now very careful that all strings are null terminated and
that no buffer overflow may occur.

will be sent upon a state change.
This, however, is not implemented yet.

is removed.

Whilst looking at my implementation of the plugins we've discussed which are

efficient substitute for the second avl tree. However, it would need to know
its size and would preferably not duplicate and own the key for each item.
Here's a patch which does this. These changes might make it easier for future
plugins to use the linked list for similar purposes, similar to the way the avl
tree does not impose any lifetime on its keys.
