modified:   ac_rm_algo.c
        Added copying of ramp and signal data into db variables,
        and writing them to the database
        Added initialization of new_max_green into psignal_data
modified:   ac_rm_table.c
        Added db_signal_data and db_ramp_data fields
modified:   clt_vars.h
        Added db_signal_data and db_ramp_data variables
modified:   control_compute.c
modified:   control_compute.h
        Removed bool typedef and changed all to unsigned int
modified:   init.c
        Commented out get_current_max_green (it's in meter_lib.c)
modified:   interface.c
modified:   interface.h
        Commented out a bunch of functions (they're in meter_lib.c)
modified:   meter_lib.c
modified:   meter_lib.h
        Added a bunch of functions that access the database
modified:   read_data.c
        Removed bool typedef and changed all to unsigned int
        Changed check of mainline_trail_status from !=MAINLINE_DETECTOR_DISABLE
        to !=MAINLINE_DETECTOR_WORKING (logic was wrong)
modified:   read_data.h
        Removed bool typedef and changed all to unsigned int
modified:   variables2.h
        Removed bool typedef and changed all to unsigned int
        Added defines of DB_SIGNAL_DATA_VAR and DB_RAMP_DATA_VAR
        Added definitions of db_ramp_data_t and db_signal_data_t structs
        (their corresponding global variables are far too large for the
        128 byte database transfer limit, so I'm copying some of the latter
        to the former for writing to data file)
