Fixing [pgpool-general: 3325] Master/Slave (stream) mode - Memory depletion

This memory leak is fixed by adding a new MemoryContext (ProcessQueryContext)
in pool_process_query function that gets reset at every query processing
loop iteration, Some required adjustments are made as part of this new
MemoryContext arrangement and now POOL_QUERY_CONTEXT has its own MemoryContext
which holds the QueryContext and its associated data.
