Detailed Description

"mci_item_t" represents values we read from a table row, and enough

to assemble to an memcached response. As described in above mci_col, we must have "MCI_COL_TO_GET" (5) column values to read. In addition, the user table could have multiple "value" columns, and it is possible to map such multiple "value" columns to a single memcached key, such value is separated by "separator" as defined in the "config_option" table. And we will assemble and disassemble the memcached value from these column values. And "extra_col_value" and "n_extra_col" is used to support multiple value columns
