Use of Log4cpp for the lob server process needs rework

[Sandhya Sundaresan]

The lobserver process is aseparate sql process that should log it's events to a seaprate log file. Need to add support for this as well as intitializing log4cpp when the lob server process receives it's first request from the master.
Some current symptoms include a core when the lob server gets it's first request. This occurs rarely .

[Sandhya Sundaresan (sandhya-sundaresan)]

Fixed and merged into mainline :I8d06716a1cac464454e01e5267460efa1859747f

lobserver process now has it's own config file and log file for logging events.
