bpo-38858: Small integer per interpreter (GH-17315)

Browse source 
Each Python subinterpreter now has its own "small integer
singletons": numbers in [-5; 257] range.

It is no longer possible to change the number of small integers at
build time by overriding NSMALLNEGINTS and NSMALLPOSINTS macros:
macros should now be modified manually in pycore_pystate.h header
file.

For now, continue to share _PyLong_Zero and _PyLong_One singletons
between all subinterpreters.
