Fix errno thread-safety under AIX

Unlike Linux or Solaris, errno under AIX is not thread-safe by
default.

This patch sets _THREAD_SAFE_ERRNO when AIX is detected in order to
force the thread-safe implementation of errno. Without this, calls
like stat() in the rrdtool plugin fail with errno incorrectly set,
leading to the inability to create previously absent rrd files.

Maybe _THREAD_SAFE should be set instead, to prevent other possible
threads-related problems, but this is enough to scratch my current
itch...

Here is the relevant part of /usr/include/errno.h on AIX:

 #if defined(_THREAD_SAFE) || defined(_THREAD_SAFE_ERRNO)
 /*
  * Per thread errno is provided by the threads provider. Both the extern
  * int
  * and the per thread value must be maintained by the threads library.
  */
 extern  int     *_Errno( void );
 #define errno   (*_Errno())

 #else

 extern int errno;

 #endif  /* _THREAD_SAFE || _THREAD_SAFE_ERRNO */

lpar plugin update

Hello,

here is a new patch against ar/lpar with the following features :

- get back to the original implementation with gauges only. A new type
"vcpu" is created (it was "lpar_pcpu" in the original)

- I tried to keep as much as possible of your changes, but some have
been reverted (the init function is back) because it was simpler for me
to port my previous code rather than adapt it to the current form. Feel
free to change them again

- the "consumed" metric might seem superfluous at first sight as it
could be calculated in the frontend in the general case. But I thought
it might come in handy when dealing with dedicated partitions, where
donated and stolen values are no easy concepts. Not everyone wants to
dig into the code and the APIs to find out what they mean and whether
they should be added to or substracted from other values...

As a side note, one  of the changes you introduced was better checking
of the return status from perfstat_partition_total() using errno. This
reminded me that under AIX errno is by default unsafe to use in a
multithreaded environment (which collectd is). I posted a fix ("Fix
errno thread-safety under AIX") on Sat, 19 Jun 2010, which if I am not
mistaken has not been merged yet.

Best regards,

Aurélien Reynaud

collection3: fix multiple hosts selection issue

When selecting multiple hosts in collection3's hosts list, and with some
plugins only (the ones that use a specific resource name such as memory
or tcpconns), the resulting graph list will be limited to one single
graph (instead of one per host).

This patch addresses this issue by modifying the name of the hash key
in the group_files_by_plugin_instance function, making it less prone
to name collisions by prefixing it by the host name.
