zonestat implemented

We are not left out in the dark yet, the gates are still open and we can see changes made to the OpenSolaris source, the source that is going to be used for Solaris 11.

Today PSARC/2010/29 zonestat was implemented, it provides enhanced observability for Solaris zones. prstat -Z can provide a nice overview of all zones on a system but it does not tell you anything about any resource capping of memory or CPU resources. There have been a perl-script with the same name available for some time which is able to extract and present a nice summary of zones and their capping and usage. This is not only a reimplementation in C, it is also architectures the new observability feature into three layers, a collection daemon, an API and a command line utility. This case has requested patch binding and it should not be hard or include any significant risk to backport it to a Solaris 10 update.

Examples from the PSARC:

Example 1: Summary of cpu and memory usage over a 5 second interval:
    # zonestat 5 1
