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.

perl plugin: Removed logging calls from call_by_name().
The function might be called from a logging callback resulting in an infinite
loop. Instead the error message is now saved in $@.

perl plugin: Added Collectd::call_by_name().
This XSUB passes on a function call to a subroutine identified by its name
passed through $Collectd::cb_name. Collectd::call_by_name does not touch the
stack (unless in case of an error), thus any arguments and return values are
kept in place.
This function is meant to be used inside Collectd.pm only.

perl plugin: Added basic multi-threading support.
This patch maps each C thread, which accesses the perl plugin, to an
interpreter based Perl thread. The implementation has been inspired by Perl's
ithreads introduced in version 5.6.0 and should be compatible (as in: can be
used side-by-side) with it. You can use threads::shared to share data
structures between threads of either implementation.

perl plugin: Use PERL_NO_GET_CONTEXT.
All Perl_* API functions have been replaced with their unprefixed
counterparts. The currently used Perl interpreter is passed along to each
function requiring access to it. This removes the need to access the global
variable keeping the pointer to the Perl interpreter in most cases but the
entry points into the plugin (i.e. the callbacks registered with collectd).
This prepares the plugin to efficiently support multiple interpreters.
