Use PerlMemShared for CopSTASHPV and CopFILE. MUCH harder than it sounds!

Need to use CopXXXXX macros everywhere and add CopSTASH_free
Add new scope type and add support for it to scope.c and scope stack
dup-er in sv.c. Add savesharedpv().
Also zealous version of Win32's vmem.h to catch all the abuses.
With this t/op/fork.t passes even with zealous checking and 
checker is point a finger at various threads/shared issues.

PL_curcop->cop_io is still an issue.
