 slapos.core version up to 1.4.4

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 updates links to slapos.git in the tree to point to new location.

We do so whole-tree except one place in stack/monitor/ :

    [download-monitor-static]
    recipe = hexagonit.recipe.download
    url = http://git.erp5.org/gitweb/slapos.git/snapshot/930be99041ea26b7b1186830e5eb56ef0acc1bdf.tar.gz
    ...

(see d8800c0b "monitor: Download statics files from snapshot")

The reason we do not update that link yet, is that 930be99041ea26b7b1186830e5eb56ef0acc1bdf
is a tree object and gitlab does not allow to dowload tree object as archives (yet ?)

So for now that link stays unconverted - and we'll think how to do with it.

no need to specify 'python = ${buildout:python}' because it is the default behaviour.

Fixes "key ipv4_set slap-configuration:ipv4" referencing a non-existing
section (woops, copy/paste...).

Also, update documentation to state that web-checker can be disabled
altogether and that frontend-url is optional (it has a working default
value).
Also, provide replacements in frontend-url for easier configuration.
Also, stop depending on slap-network-information magical section.

Develop is bad anyway, but at least this fixes varnish software release in
master branch.

that is required to compile varnish VCL in runtime.
