Update to the internal master as of 2018-11-15.
This has a lot of gratuitous whitespace change, but on the plus
side it's built using the same tooling that's used for AMDVLK,
which should help going forward.
This uses C++11 initializer lists.
I just overwrote all Mesa files with internal addrlib and discarded
hunks that we should probably keep, but I might have missed something.
The code depending on ADDR_AM_BUILD is removed. We can add it back next
time if needed.
