Pcbnew: fix a very old bug in DRC, pad to pad drc tests: sometimes a test...

Pcbnew: fix a very old bug in DRC, pad to pad drc tests: sometimes a test between a rectangular pad and an oval pad was skipped.
Segment Hit Test: enhanced detection near segment ends (noticeable for instance when clicking on short tracks in Pcbnew.
Remove duplicate code about segment hit test.
remove unused file.
