Merge from Widevine repo of http://go/wvgerrit/169050
- Update changelog
- Update copy parter files script to include linux port
- Update opk_partner_test script (used to make sure everything works out
of the box) with third party dependencies, refactored downloads into
a public setup.sh script
- Remove WTPI_BUILD_INFO from OPK makefiles and gyp files, since it is
no longer needed
- Remove FILES.md since it is out of date and ree-sources.mk and
tee-sources.mk satisfy the same purpose
- Add debug flag in comments for OP-TEE and Linux ports. As a hint for
how to enable debug in OPK
- Remove oemcrypto_build_info.h since it is no longer needed. Move the
XSTR macro it contained to oemcrypto_api_macros.h
- Add provisioning method macro to OPTEE and Linux build files to hint
at how to build Prov 2 and Prov 4 using the same build files but
different build-time values.
