252f4dc6c9 Issue #16350, part 2: Set unused_data (and unconsumed_tail) correctly in decompressobj().flush(). 
Additionally, fix a bug where a MemoryError in allocating a bytes object could
leave the decompressor object in an invalid state (with its unconsumed_tail
member being NULL).

3db8a3432b Change more tests to use import_module for the modules that 
should cause tests to be skipped.  Also rename import_function
to the more descriptive get_attribute and add a docstring.

c856fa811d Add a test to make sure zlib.crc32 and binascii.crc32 return the same thing. 
Fix a buglet in binascii.crc32, the second optional argument could previously
have a signedness mismatch with the C variable its going into.
