From: Florian Forster <octo@leeloo.lan.home.verplant.org>

This patch introduces per-socket, per-command permissions to the RRD
caching daemon, RRDCacheD. This allows administrators to limit access to
the daemon in a fine-grained manner.

The patch removes the command line option `-L' and introduces `-P'
instead. The option must appear *before* the `-l' option and the given
permissions are set for all following sockets or another `-P' option.

For example:

  rrdcached -P FLUSH,PENDING -l 10.2.3.4 -P UPDATE -l unix:/some/path

Allow `FLUSH' and `PENDING' commands to clients connected via IPv4
networking and `UPDATE' to clients connected via a UNIX domain socket
only.

There are a couple of exceptions:

  - The commands `HELP' and `QUIT' are always allowed.
  - If the command `BATCH' is allowed, the command `.' is automatically
    allowed, too.

By default, i. e. if no `-P' option is specified, all commands will be
allowed. As a shortcut to reset the behavior to the default behavior,
you can use the slightly hackish `-P ""' syntax.

rrd_tune HW Update

Allow to set the smoothing window (alpha, beta, gamma) to zero.

I'm using rrdtool 1.3.8 with abberant behavior detection from the Brutlag
method. I need to use a week seasonality and no smoothing for the SEASONAL
and DEVSEASONAL. So I use rrdtune in order to set the smoothing window to
0.0. This calls the set_hwarg(). But this method is also used to tune the
alpha, beta and gamma that can't be set to 0.0 So when I tune my smoothing
window size to 0.0, it returns -1 due to the if(window<=0.0) then do
nothing. I join here a small correction with a differnent method used to set
only the smoothing window size and allowing it to be zero.

While restoring, rrd_restore uses between 30 and 40 times as much memory as
the size of the rrd file to be restored. This is due to the use of libxml2
for parsing the the whole file prior to turning it into rrd structs.

This patch switches rrd_restore to using the xmlTextReader interface for
incremental consumtion of xml files. This reduces the memory requirements to
about twice the size of the rrd file which should be quite manageable for
most cases.

The parsing is about 25% less efficient than with the original libxml2
version of rrd_restore. This could be in part due to the more liberal use of
malloced memory. Optimizing this is for another day though.
