Readded the tsan suppressions file
forgot the export
Try again for tsan supp file
First round of tsan suppressions.
tsan currently fatal exits, so try some options from chromium.
Travis now uses llvm symboliser.
Finally got around to enabling a ThreadSanitize pass per commit for Travis.
Added running-in-ci to travis
Fixed bug where --lto wasn't turning on the optimiser for LTO output. Sorry.

Added a benchmark testing for latency under concurrency loads.
Fixed previous build break with thread sanitiser detection.

benchmark_latency now gates the threads to improve concurrency, and calculates
OS sleep overhead.
Added a new FAQ entry on AFIO execution latencies.
Tried fixing up path to image.
Out by a dir level.
Updated build status image urls to reflect new CI config.
Added gate before benchmark threads run.
First attempt at a reorg for modular boost. There is going to be a ton of breakage.
Reorganised source code structure to fit modular Boost. AFIO is now a Boost v1.56
module just like any other. Obviously this will break source code compatibility
with all preceding Boosts.
Added note about how to compile the PDF.
Removed more pre-modularisation cruft.
Repaired the docs breakages from modular Boost conversion.
