Ensure that PySet_Add() operates on a newly created frozenset, like PyTuple_SetItem does.
Add PyFrozenSet_Check(), which was not needed before; The list of Py*Set_Check* macros seems to be complete now.
Add missing NEWS entries about all this.

Correct test_mailbox on win32: since the test sets a custom 'colon' attribute
to the main mailbox, copy it to secondary mailbox instances.

Patch #1953
I implemented the function sys._compact_freelists() and C API functions PyInt_/PyFloat_CompactFreeList() to compact the pre-allocated blocks of ints and floats. They allow the user to reduce the memory usage of a Python process that deals with lots of numbers.
The patch also renames sys._cleartypecache to sys._clear_type_cache

-.. function:: _cleartypecache()
+.. function:: _compact_freelists()
- Clear the internal type lookup cache.
+ Compact the free list of floats by deallocating unused blocks.
+ It can reduce the memory usage of the Python process several tenth of
+ thousands of integers or floats have been allocated at once.
+
+ The return value is a tuple of tuples each containing three elements,
+ amount of used objects, total block count before the blocks are deallocated
+ and amount of freed blocks.

+.. function:: _clear_type_cache()
+
+ Clear the internal type cache. The type cache is used to speed up attribute
+ and method lookups. Use the function *only* to drop unnecessary references
+ during reference leak debugging.
+
+ This function should be used for internal and specialized purposes only.
