[Owncloud] testers needed.

[Robin Appelman]

Hi,

the last couple of weeks I've been working on a series of larger
changes that will enable transparent server-side encryption.

Due to the nature of the changes, merging these changes into master
without a lot of testing could end up in data-loss
for unsuspecting users, that's why I would like some help to test these changes.

The changes are on two branches in git:
 - filesystem:
       Provides the improvements to the filesystem layers that were
needed to correctly integrate encryption into it,
       and holds the automatic database upgrading system to make those
improvements work on existing installations.

       For this branch it's important that it is tested as upgrade on
top of an existing installation, just checkout the remote branch,
       navigate your browser to ownCloud and the automated database
updates should do the rest.
       While testing branch may result into database corruption,
possibly loosing user accounts, calendars and contacts. Stored files
       will remain safe.

       After the update is successful the filesytem will be indexed
and no changes should be visible besides incorrect sorting of
files/folders
       and faster loading of folders with a lot of files/sub folders.

 - encryption
       Provides transparent server-side encryption for files.

       This branch should be tested as a clean installation in order
to prevent possible any migration errors here.
       Upgrading to this branch from an existing installation will not
work, rerunning the setup is necessarily.

       No visible changes should exist for this branch except the one
listed for the filesystem branch, any file uploaded through the web
interface
       or webdav should get encrypted automatically (you can test this
by trying to open the file directly from the servers filesystem)
except
       some blacklisted file types (audio, video, images).

If you encounter any problems, please list the used sql server, php
version and whether or not it was upgraded from an existing
installation.

Any help testing is greatly appreciated.
