Debian patches to forward upstream?

[Quanah Gibson-Mount]

Hi folks,

The cyrus-sasl project is re-awakening after many years of relative 
dormancy.  I noticed that Debian has some fixes for cyrus-sasl that have 
not been contributed upstream (that I could find at least).  For example:

0005-Fixes-in-library-mutexes.patch

It would be great if this could be filed as an issue with the Debian 
history as to why it was created (if possible) and a relevant pull request 
done as well at <https://github.com/cyrusimap/cyrus-sasl/>

Thanks!
