Bug#903475: sipsak: MD5 auth broken

[Bastian Triller]

Package: sipsak
Version: 0.9.6+git20160713-2
Severity: important
Tags: patch

Dear Maintainer,


using sipsak with a proxy, that challenges the UA for credentials, does not
(always?) work e.g. to REGISTER:

sipsak -U --password secret -s sip:myuser at domain

This bug was fixed upstream [1].

Please integrate attached patch.

Thank you.

Subject: [PATCH] Fix MD5 auth calculation on many 64-bit systems.

Unsigned long is very often 8 bytes, not 4. Use stdint.h if available.
