2407ac9a4b follow-up of #3997: since 0xFFFF numbers are not enough to indicate a zip64 format, 
always try to read the "zip64 end of directory structure".

Also fixes
- Issue #1526: Allow more than 64k files to be added to Zip64 file.

- Issue #1746: Correct handling of zipfile archive comments (previously
  archives with comments over 4k were flagged as invalid). Allow writing
  Zip files with archives by setting the 'comment' attribute of a ZipFile.

b89a096d6d Use zlib's crc32 routine instead of binascii when available. zlib's is faster 
when compiled properly optimized and about the same speed otherwise.

da407232e0 Document that zipfile decryption is insanely slow and fix a typo and 
blatant lie in a docstring (it is not useful for security regardless of
how you spell it).

0c63fc23c4 Fix zipfile decryption. The check for validity only worked on one 
type of encrypted zip files.  Files using extended local headers
needed to compare the check byte against different values.  (according
to reading the infozip unzip crypt.c source code)

Fixes issue1003.

f79c32dbfb ZipFile.close(): Kill the other struct.pack deprecation 
warning on Windows.

Afraid I can't detect a pattern to when the pack formats decide
to use a signed or unsigned format code -- appears nearly
arbitrary to my eyes.  So I left all the pack formats alone and
changed the special-case data values instead.

352bf0d7ee ZipFile.close(): Killed one of the struct.pack deprecation 
warnings on Win32.

Also added an XXX about the line:

                pos3 = self.fp.tell()

`pos3` is never referenced, and I have no idea what the code
intended to do instead.
