    ipmi: use SIGIO instead of SIGUSR2 to avoid conflict with JVM
    
    Java uses SIGUSR2 to suspend/resume threads. The OpenIPMI plugins also
    need a signal to resume its event loop when setting a timer. They can't
    both use the same signal. We ask OpenIPMI to use SIGIO instead.
    
    This should fix #114.

    write_http: make callback names context-dependent
    
    This allows multiple destinations to work again (fixes #821), using the
    same logic as other write plugins.
    
    The callback name would now be something like:
        `write_http/http://example.com/endpoint`
    which is not very nice.
    
    The next step would be to change this plugin to use `<Node>` blocks
    like many others, and pass the URL as a parameter inside each instance
    block. So I see this patch as the minimum required to let 5.3 and 5.4
    users use this plugin with multiple destinations.

    collectdctl command hangs on AIX and returns error 0 on Solaris.
    
    Summary:
    Problem: collectdctl command hangs on AIX and returns error 0 on Solaris.
    
    Root cause - client (collectdctl) and server (collectd daemon) are using fprintf to communicate using Unix domain socket, Since fprintf buffers, command sent by client did not reach server, since client does not get the response, it closes the socket which forces the client to flush the command, now server receives the command, when responding, it gets socket error because the client already closed the socket.
    
    Solution: Added flush after all fprintf calls.
    
    Test Plan: Tested collectdctl on AIX and SunOS for listval, getval commands

    Let snmp_synch_response deal with PDU freeing
    
    When reading from tables, upon errors the PDUs sent are already
    freed by snmp_synch_response since they are right after
    snmp_send is called.
    
    This commit syncs collectd's approach with other occurences of
    snmp_synch_response calls.
    
    There might be a few corner cases where we leak PDUs, but it
    is unclear how to check for those since we would need to
    have an indication that snmp_send was never called, which
    as far as I can tell is not possible.
    
    The potential for failure in snmp_send is rather low and will
    be easily spotted though, since when crafting invalid PDUs
    snmp send will constantly fail and since valid configurations
    can never leak memory.
    
    This fixes #804

    network: don't enable gcrypt thread callbacks when gcrypt recent enough
    
    From `gcrypt.h`:
    
    > NOTE: Since Libgcrypt 1.6 the thread callbacks are not anymore used.
    > However we keep it to allow for some source code compatibility if used
    > in the standard way.
    
    Otherwise, we get a deprecation warning which is turned into an error:
    
    ```

    write_redis: re-add colon dropped in b7984797
    
    When running f3706b0b87, the following command gets sent to redis:
      "ZADD" "collectd/hostname/entropy/entropy" "1415487432.000000" "1415487432:932"
    Meaning the value actually stored, and later returned by redis is:
    "<timstamp>:<value>".
    
    b7984797 accidentally dropped the comma separating the timestamp and the
    value, which leads the plugin to store a somewhat confusing value in
    redis:
      "ZADD" "collectd/hostname/entropy/entropy" "1415487432.000000" "1415487432932"

    redhat initscript: add timeout when stopping the daemon
    
    This mitigates the risk of having 2 daemons running simultaneously
    during a short period, on restart.
    
    The debian package's initscript does the same thing, using the same
    timeout value.

    curl_json: fix the array access implemented in f1e1e37e
    
    In the avl-tree we store two different structs, cj_key_t for the value
    we search, c_avl_tree_t for sub-nodes.
    The old version does assume when it will find a key, and when a tree,
    which doesn't have to be right in all cases.
    Therefore we utilize the magic to revalidate this cast.
    Being able to tell tree from key, we now can also implement array access
    on the right most node of the tree-path.

    Use the complain mechanism to report write failures.
    
    This ensures that we don't spam the log for each submitted value. Instead, an
    exponential backup is used to report permanent errors starting at one message
    per second.

    cpu plugin: Remove temperature code for Mac OS X.
    
    This code would throw an error for some systems, because the temperature
    couldn't be read. Since the plugin still works in general, this was very
    confusing to users. Becaus the temperature, even when read sucessfully, was
    never dispatched, remove the code entirely. We might want to add this back to
    the apple_sensors plugin eventually.
