* upgrade to rand 0.7.0 (MSRV 1.32) * upgrade to parking_lot 0.9.0 * Remove last non-dev dependency on rand crate (#1324) Use std RandomState for XorShift seeding. This allows dropping _rand_ crate dep here, accept as a dev dependency for tests or benchmarks. * increase CI MSRV to 1.31.0 * increase nightly for CI TSAN tests * add TSAN suppressions for recent rand related updates * make latest TSAN suppression patterns more general * upgrade tempfile dev dep for common rand version But avoid tempfile 3.2 for now, since history demonstrates it bumps rand versions and MSRV in MINOR updates. * update (dev dep) env_logger to latest 0.6 * reactor, threadpool: bump PATCH versions, doc links, change logs [ci-release]

|
# point it has not gained ownership of the node and another thread might beat
|
|
# it and take ownership of the node first (touching the next pointer). The
|
|
# original pop operation will fail due to the ABA guard, but tsan still picks
|
|
# up the access on the next pointer.
