Add user ID to VmInfo and display in clients This commit adds user ID information to the VmInfo Pojo, which is gathered by SystemBackend. The UID for a VM is collected by parsing /proc/${pid}/status, and we then get the username for the UID from the native function getpwuid_r. Both the vm-info command and the VM Overview tab of the Swing GUI now show the user under Process Information. I took inspiration from the id Unix program for the formatting, which is "uid(username)". The native component of this commit is added to agent-core for use by system-backend, this was done on request by Mario since agent-core already has a native component for getting the hostname. I made this component an OSGi service primarily to hide its implementation details. Reviewed-by: omajid, jerboaa Review-thread: http://icedtea.classpath.org/pipermail/thermostat/2013-May/006674.html
