Ah, I found yet one bug.

>>> zlib.decompress(zlib.compress(b'abcd'), 0, sys.maxsize+1)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
SystemError: Negative size passed to PyBytes_FromStringAndSize

There are similar bugs in decompressor's methods decompress() and flush() but it is hard to reproduce them.

The maximal length value should be bounded not only with UINT_MAX, but with PY_SSIZE_T_MAX too.

I would merge sval and uval into one variable of type Py_ssize_t.
