Slapos.toolbox has a new dependency to pycurl, which fails to compile if libcurl cannot be found. This commit adds the component/pycurl dependency to most of the Software Releases which have a dependency to slapos.toolbox.

I tried to do it globally, so I couldn't check the compilation of all the modified SRs. Is it a way to test that all SRs still compiled ?

Also, did I forget some important SR ?

This is backported to ZODB-3.10 https://github.com/zopefoundation/persistent/pull/44

The patch is needed for wendelin.core to being able to relase not needed
memory.

- logrotate: make stack with cfg.in containing sections for logrotating with dcron and gzip
- neoppod: use this logrotate stack

because the recent version of paramiko (>= 2.0.0), that is a part of
slapos.toolbox's dependencies, depends on cryptography insead of
pycrypto.

NEO is still in heavy development and it must be easy to update code on
existing deployment.

This fixes the following random failures:
