src/common.c: Fixed a race condition in check_create_dir().

Between checking for the existence of a directory using stat() and creating
the directory using mkdir(), another thread might have already created the
directory thus causing mkdir() to fail with errno == EEXIST. This case is now
handled sanely, no longer causing the function (and thus some write callback)
to fail in this case.

Most likely, this only happens during startup when creating the data
directories - later, no two threads should try to create the same directory.

Interestingly enough, I frequently encountered this issue on a single core
machine.

current graph list to a cookie and appending graph list read from
cookie to the currently displayed list.

A future extension would be to allow saving/loading named graph lists

contrib/php-collection: Add a PHP frontend for graph generation.

Hi,

Attached is a patch with a set of PHP files for a complete graphing
environment for collectd-generated RRDs.
Before generating a graph with rrdtool it can tell collectd to flush
the RRDs that are about to be used.

The interface is built with dynamic HTML.
It provides following options:
 - host selection
 -> plugin selection
 --> plugin instance selection
 ---> type selection
 ----> type instance selection (or meta graph)
 - linear / logarithmic Y-scale
 - verbose / minimal legend
 - [Add Graph] [Remove all Graphs] [Refresh Graphs]
For each displayed graph:
 - Move above previous graph
 - Refresh graph
 - Remove graph
 - Move below following graph

I tested on following browsers:
- Firefox-3.0
- Safari-3.2 (Win32)
- Konqueror (KDE-4.1.3)
- Webkit (webkit-gtk-0_p40220)
- Internet Explorer (6, 7, 8rc - CSS layout issues with <8)

Dependencies:
- PHP-5 (might run with PHP-4)
  > GD suport for error images
  > Ability to execute rrdtool binary
  > Unix socket for FLUSH support
- RRDTool (rrdtool graph, rrdtool info)

TODO: complete/improve graph definitions in definitions.php
 though there is code to generate basic graph for any RRD of

network plugin: Fix an invalid size of buffer being used.

`buffer' is a pointer, giving 4 or 8 bytes, depending on the architecture (and
not depending on the actual buffer size). This results in the `type' being sent
much more often than necessary and sometimes not sending a new type when is was
actually necessary. The only prominent case in the default configuration(s) was
`cpufreq' being used instead of `cpu', though.

While in the process, the global `type' buffer was replaced, because an
appropriate buffer is in `value_list_t' now.
