Draw w/auto drc during DRC causes crash

Bug Description

DRC uses InitConnectionLookup() to allocate some (global) memory. When it pauses to show you a DRC error it is possible to cause a InitConnectionLookup/FreeConnectionLookupMemory pair which will cause the DRC to crash when it resumes. The easiest way to do this is to be in line drawing mode when you start the DRC and then inadvertently click when the cursor is warped to the problem location. If AutoDRC is on, a LookupConnection will be initiated to find what net you are drawing on. That will trigger the init/free. When you click 'next' in the DRC dialog PCB will crash.

It looks like the only safe way to handle this is to free before the DRC dialog and init again after. There could be more objects after the dialog, after all.
