2017-09-08lib: clean up header includesDaniel Vetter
Just a bit of OCD, I like it when connections within library modules are a bit more obvious. igt.h is ok for tests, but let's use individual include lines for libraries consistently. Also order standard includes before igt ones. v2: Rebase.

2017-08-21lib: Add ALSA library with dedicated helpersPaul Kocialkowski
This introduces an ALSA library, with dedicated helpers for handling playback and capture. It handles ALSA device identification and configuration as well as a run loop with callback mechanisms for feeding output data and handling input data. This library paves the way for testing audio going through display connectors, such as HDMI.
