When we run the VTS of GraphicsComposerAidlCommandTest, we always meet
segmentation fault issue in some test items. VTS test items crashed
when it deleted the layer or display from resource manager and try to
go next loop.
The problem is the test item try to delete the layer iterator or
display iterator in the loop, so the iterator become an invalid
iterator. Then it try to use the invalid iterator for going to next
iterator. This behavior caused segmentation fault. We use different
way to fix deleting layer and deleting display.
Delete layer: Test item always delete all layer for each display, so
we always delete layer via get the first iterator until
the resource manager is empty.
Delete display: Test item only delete virtual display, so we move the
physical display to a temporary map. After delete all
virtual display, we swap the temporary map and
original map.
Bug: 243781450
Test: 1. test GraphicsComposerAidlCommandTest.SetLayerColorTransform
for deleting layer
2. test GraphicsComposerAidlCommandTest.SetOutputBuffer
for deleting disply
