[WIP] Custom wrapper to handle commands in oC

[sharidas]

A custom wrapper to handle command transfer-ownership.
In this wrapper we can make changes for functions like
fopen or any other routines.

Signed-off-by: Sujith H sharidasan@owncloud.com

Description

A custom wrapper created along with a custom view so that changes required for common functions like fopen arguments or so can be handled here. Primarily the focus is for command transfer-ownership and later we would use for other command like recreate master key.

Motivation and Context

This change would prevent the modification to common routines which were made to arguments of functions like fopen or copy etc. And use this wrapper for custom changes.

How Has This Been Tested?

• Scratch installation of oC and create 2 users
• Verified transfer ownership command works with and without encryption between two users.
• Verified Recreate command for master key works on the same setup.
