Replace SEVERITY_ERROR by RPT_SEVERITY_ERROR to avoid collision with a system definition.
Replace other SEVERITY_XXX by RPT_SEVERITY_XX for consistency.
Fix compil warnings and some other compil issues.
The pin name defined in Eeschema is now available as pad info.
Useful for the board designer (the pin function is displayed in the message panel).
Needed for the Gerber P&P files.
- Previously a warning was generated even for not connectable pads
(pads not on copper layers or without pad name).
- The test is now optional and is disabled by default.
(pads without corresponding pin is schematics are a frequent case)
