CHANGED footprint positions files -> component placement files.
Not all footprints get placed, so component is a more neutral word.
Use of "placement" instead of "positions" removes the double-plural
that makes footprint positions files such a mouth-full.
Fixes https://gitlab.com/kicad/code/kicad/issues/7097
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.

Make the data generation code separate from the dialog code.
The dialog itself does not include anymore the data generation code.

Added checks to StrCmpNum() function in common/sting.cpp to prevent
iterating past the end of the sting. Also removed length of string
parameter since it did not seem to be used anywhere.
