Trend computing function

      Description

      In the attachment is a dirty hack that adds support for trend computation based on function evaluate_SUM. The function does linear regression on the data an returns the trend of the fitted function.

      Right now I'm using it to predict when the space on disk will fill:

      1) zabbix agent item: vfs.fs.size[/,pfree]
      2) calculated item that computes time to live in hours named "vfs.fs.size[/,ttl]":
      -last("vfs.fs.size[/,pfree]")/(trend("vfs.fs.size[/,pfree]",21600)*3600-0.000001)
      3) trigger
      {vfs.fs.size[/,ttl].last(#1)}>0&{vfs.fs.size[/,ttl].last(#1)}<48
