/*
* Functions to read a netlist. They are:
* - Load new footprints and initialize net info
* - Test for missing or extra footprints
* - Recalculate full connectivity info
*
* Important remark:
* When reading a netlist Pcbnew must identify existing footprints (link
* between existing footprints an components in netlist)
* This identification can be from 2 fields:
* - The reference (U2, R5 ..): this is the normal mode
* - The Time Stamp (Signature Temporarily), useful after a full schematic
* reannotation because references can be changed for the same schematic.
* So when reading a netlist ReadPcbNetlist() can use references or time stamps
* to identify footprints on board and the corresponding component in schematic.
* If we want to fully reannotate a schematic this sequence must be used
* 1 - SAVE your board !!!
* 2 - Create and read the netlist (to ensure all info is correct, mainly
* references and time stamp)
* 3 - Reannotate the schematic (references will be changed, but not time stamps )
* 4 - Recreate and read the new netlist using the Time Stamp identification
* (that reinit the new references)
