OpenXR 1.0.6 release (24-January-2020)

Patch release for the 1.0 series.

This release contains, among other things, a substantial simplification and
cleanup of the loader, which should fix a number of issues and also make it
forward compatible with extensions newer than the loader itself. As a part of
this change, the loader itself now only supports a single `XrInstance` active at
a time per process. If you attempt to create a new instance while an existing
one remains (such as in the case of application code leaking an `XrInstance`
handle), the loader will now return `XR_ERROR_LIMIT_REACHED`.
