Use atomic exchange to mark completion in absl::once_flag
This prevents a potential for a missed wakeup if one thread marks
itself as a waiter while another thread is completing the invocation.

fix: work around gcc-4.8 bug in disjunction
See https://godbolt.org/z/i7-AmM for a repro of the bug.
I realize that Abseil no longer supports gcc 4.8 officially
(https://abseil.io/docs/cpp/platforms/platforms), but Cloud C++ still supports
gcc 4.8 officially, and so it would be nice to get this simple fix in.
fixes https://github.com/abseil/abseil-cpp/issues/718

Change spelling of internal detail from `Invoke`/`InvokeT` to `invoke`/`invoke_result_t`.
This matches the spelling of the C++17 standard library names that perform the same operations.

Slight restructuring of absl/random/internal randen implementation.
Convert round-keys.inc into randen_round_keys.cc file.
Consistently use a 128-bit pointer type for internal method parameters. This allows simpler pointer arithmetic in C++ & permits removal of some constants and casts.
Remove some redundancy in comments & constexpr variables. Specifically, all references to Randen algorithm parameters use RandenTraits; duplication in RandenSlow removed.

Change many distribution tests to use pcg_engine as a deterministic source of entropy.
It's reasonable to test that the BitGen itself has good entropy, however when testing the cross product of all random distributions x all the architecture variations x all submitted changes results in a large number of tests. In order to account for these failures while still using good entropy requires that our allowed sigma need to account for all of these independent tests.
Our current sigma values are too restrictive, and we see a lot of failures, so we have to either relax the sigma values or convert some of the statistical tests to use deterministic values.
This changelist does the latter.
