    perl plugin: Execute END blocks in main thread only.
    
    Each END block is executed during perl_destruct() which happens once for each
    ithread. As the number of ithreads are in no way related to any Perl plugins
    this is not what we want. Now, each END block is only executed when the main
    threads terminates (which happens after any other Perl thread has been shut
    down).

    src/Makefile.am: Add installation directory defines to AM_CPPFLAGS.
    
    Those definitions used to be available when compiling collectd itself only.
    However, they should be available to the plugins as well - else, different
    paths would be used within different parts of collectd.

    Collectd.pm: Improved error handling of failed callbacks.
    
    If call_by_name() failed, it will be handled the same way as if the callback
    returned "false". The $@ variable may now be used by plugins as well to
    describe errors in greater detail.

    collectd-perl(5): Updated documenation of plugin_register().
    
    Document the usage of names instead of references to identify callbacks.

    Collectd.pm: Use threads::shared to share @plugins between threads.
    
    The list of plugins has to be common to all threads to be able to (un)register
    callbacks after initialization. As threads::shared is not able to share
    references to subroutines the callbacks now have to be identified by their
    name. Collectd::call_by_name() is used to execute the callbacks.

    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 $@.

commit e08d6907db8ad7d9b411e35b499ff82ce3cd9e01
Author: Sebastian Harl <sh at tokkee.org>
Date:   Sat Nov 17 18:38:45 2007 +0100

    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.
