#68 Configuration parameters to be moved into shared memory

[Kishor Amballi]

At present implementation any change in csql.conf file parameter needs the csqlserver to be restarted otherwise the behavior is undefined.

When server boots up it reads csql.conf file and stores each parameter in its address space. When clients connect they also read from csql.conf and
store those parameters in their respective address spaces. Instead the server should store all the server related parameters in shared memory
(system database) and the clients should read these parameters from the shared memory. Clients should read only client related parameters from
the csql.conf file that is specific to each client.

At present the parameters are static and they are not dynamically changeable. This feature should make sure that the parameters are changeable
dynamically.
