* Determine the epoc root for the currently active SDK.
*
* The algorithm used is as follows:
* 1. If environment variable EPOCROOT is set and points to an existent
* directory, this is returned.
* 2. The location of devices.xml is specified by a registry key. If this
* file exists, it is parsed.
* 3. If the EPOCDEVICE environment variable is set and a corresponding
* entry is found in devices.xml, and its epocroot value points to an
* existent directory, it is returned.
* 4. If a device element marked as default is found in devices.xml and its
* epocroot value points to an existent directory, this is returned.
* 5. An empty string is returned.
*
* Any return value other than the empty string therefore is guaranteed to
* point to an existent directory.
