Symbols in a loaded overlay are not currently available to subsequently
loaded overlays because the properties in the overlay's __symbols__
node are not loaded into the live device tree.

Patch 1 is unittests to test patches 2 and 3.

Patch 2 fixes a problem discovered while developing patch 3.  If
a node name in an overlay has a unit-address then the overlay
code does not correctly match the node name against an existing
node in the live tree.

Patch 3 adds the properties in an overlay's __symbol__ node to
the overlay changeset.

This patch set was created on top of v4.12, with Rob's pull request
for 4.13 added (https://lkml.org/lkml/2017/7/6/691).  Thus this
series should apply on 4.13-rc1 when that becomes available.  I will
re-test on 4.13-rc1.
