[RFCv2,libdrm 2/2] tests: tegra: Add stream library test

Fri Apr 12 03:42:00 PDT 2013
This patch adds a minimal test set for the stream library and host1x
kernel interface.
The test verifies that the driver (or library) is able to:
- Increment, read and wait for syncpoint values
- Use a host1x channel to do host1x operations
- Handle submit timeout correctly
- Do relocations to buffer
- Allocate and release memory
- Use stream pools correctly
