akonadi-mysql subpkg

[Rex Dieter]

Here's an initial attempt at creating a akonadi-mysql subpkg.

It's purpose includes:
* provide a way for users/admin's to more-easily control which akonadi 
backend gets used by default.  when akonadi-mysql is present => mysql, 
if not => sqlite
* allows mysql (and friends) to drop out of fedora's critical path 
(which the mysql maintainer isn't fond of)

Once built, we can add akonadi-mysql to comps to get installed by 
default (1)

I've tested upgrading from pristine akonadi setup/config as well as one 
with an existing customized /etc/xdg/akonadi/akonadiserverrc file.


Any comments, thoughts, feedback?

with me last time the topic was debated.
