Answer 1

As this is a completly different answer. Your problem is not stof/doctrine-extensions-bundle, it's white-october/pagerfanta-bundle. Kids, read the error messages!

How i knew this? Simply copied your composer.json, executed update and got a meaning error message:

 white-october/pagerfanta-bundle dev-master requires symfony/framework-bundle >=2.2,<3.0 -> satisfiable by symfony/symfony[v2.2.0, v2.2.1], symfony/framework-bundle[v2.2.0, v2.2.1].

which means, actual versions of pagerfanta-bundle requires symfony 2.2, so you have to upgrade, if you want to use it.
