Disable app store for EE by default

This disables the app store for EE versions by default to address some problems caused by the wrong assumption that "Official" means supported by ownCloud Inc.

Administrators can still enable the app store by setting `appstoreenabled` to true in the config file.

Swift primary storage tests

Catch "missing table" exception when cleaning up locks

Fix search operations for the Node API

[webdav] Check if source can be deleted before move

Fix scrollbars in public template

Only use zip64 when we have 64 bit php

Move the setup of external share mounts to a mountprovider

If we perform a move we need to make sure first that the source can be
deleted. Else the dest might be cleared but the move will fail later.

* Added unit tests

Eventually we need more and better checking here.

Remove oc_storages entries after removing ext storages

Mark shares as dirty when changing permissions

When removing external storages, either system-wide or user-wide,
automatically remove the matching oc_storages and oc_filecache entries.

This can only work if the backend configuration doesn't contain any
substitution variable $user in which case the storage id cannot be
computed, so this case is ignored for now.

Propagate shares etag when group membership changed

use default config for swift primary storage test config

allow testsuite to complete

fix timeout, script cleanup, enable debug for now

use btrfs loopback device, requires privileged container and absolute path

throw exception when storage has problems

debug by echo ...

sleep more, more debug
