Reminder to myself.

[wilmer]

I'm rejecting the systemd one because Daemon mode is *NOT* the recommended way to use BitlBee (and I'd like packagers to not enable it by default either, although automatic restarting does make it a little more acceptable).

The others seem fine though. Have enough people used the NSS-DES change with success? If so, I can drop the des.c file completely.

[wilmer]

I've applied the syslib + installP patch. The NSS patch adds code to a file ignoring its own coding style entirely (spaces instead of tabs, different use of spaces, etc) and I'm tired of cleaning up patches like that.
