Final GSoC revision of SIGAR I_S plugin

The GSoC is about to end up and it is time to sum up what has been done within the last weeks.

News

*Error handling added. Plugin uses the following mechanism to gather and report errors. When we can't load/open SIGAR library or get any information from it we pass the error to user informing about that. On the other hand when only some information is not available we rather print warning about that to MySQL .err file.
Also we check for return value for each schema_store_record function.

*Plugin has been merged into the MySQL 6 server code. Now you can download and compile the MySQL server with SIGAR plugin already being there.

Downloads

SIGAR plugin merged into the MySQL server is available at lp:~m.ch/mysql-server/mysql-6.0-sigar-plugin.
