New minor version.

[Xi Ruoyao]

Version 1.3 has these key updates from 1.2.13:

• Building using K&R (pre-ANSI) function definitions is no longer supported.
• Fixed a bug in deflateBound() for level 0 and memLevel 9.
• Fixed a bug when gzungetc() is used immediately after gzopen().
• Fixed a bug when using gzflush() with a very small buffer.
• Fixed a crash when gzsetparams() is attempted for a transparent write.
• Fixed test/example.c to work with FORCE_STORED.
• Fixed minizip to allow it to open an empty zip file.
• Fixed reading disk number start on zip64 files in minizip.
• Fixed a logic error in minizip argument processing.

There's a report on IRC

<r1c0n3r0> meh... OpenSSH fails with zlib1.3 installed, https://bugzilla.mindrot.org/show_bug.cgi?id=3604 , fix: https://github.com/openssh/openssh-portable/commit/cb4ed12ffc332d1f72d054ed92655b5f1c38f621

(i've neither checked the fail nor the patch)

We can just pass --without-zlib-version-check instead of patching it. Anyway we know we don't have zlib < 1.2.3 (zlib-1.2.2.4 was released in 2004 :).

If needed, openssh can be fixed with a sed.

configure.ac in openssh:

   n = sscanf(ZLIB_VERSION, "%d.%d.%d.%d", &a, &b, &c, &d);
-  if (n != 3 && n != 4)
+  if (n < 1)
	exit(1);
