configure: add --enable-tsan flag + fiber annotations for coroutine-ucontext
We tried running QEMU under tsan in 2016, but tsan's lack of support for longjmp-based fibers was a blocker: https://groups.google.com/forum/#!topic/thread-sanitizer/se0YuzfWazw Fortunately, thread sanitizer gained fiber support in early 2019: https://reviews.llvm.org/D54889 This patch brings tsan support upstream by importing the patch that annotated QEMU's coroutines as tsan fibers in Android's QEMU fork: https://android-review.googlesource.com/c/platform/external/qemu/+/844675 Tested with '--enable-tsan --cc=clang-9 --cxx=clang++-9 --disable-werror' configure flags.
