[OE-core] connman dependency of readline

[claus.stovgaard at gmail.com]

Hi

I am starting to use Yocto / OpenEmbedded, where I was looking into
using ConnMan as network manager.

Though I was wondering about the readline dependency.
Looking at the recipe 
https://github.com/openembedded/openembedded-core/blob/master/meta/recipes-connectivity/connman/connman.inc
it is set to always depend on readline in the DEPENDS variable, even
though as far as I know it is only the connmanctl which depend on
readline.
In EXTRA_OECONF the --enable-client is hardcoded.

The client is though not included in the image unless you also add
connman-client.

So I am thinking on creating a patch where I create a
PACKAGECONFIG[readline] like bluez5, as I would not need the client and
will need not to include readline because of GPLv3.

I guess email is the prefered way for patches compared to github pull
requests?

Instead of my idea of creating as PACKAGECONFIG[readline], is there a
better way so it is only included if connman-client is used, instead of
just connman?

Have a nice weekend.
