In sanitizer mode, add generation integers to b-tree nodes and iterators and validate that iterators have not been invalidated already when they're used.
Even though generation integers are stored in all nodes, we only use the one stored in the root node for validation. The reason we keep one in all the nodes is that nodes can become a root node after they are allocated.
Also change the order of args in init_leaf to not violate the style guide.

Fix CordRepRing diabolical growth
The 'Mutable' function in CordRepRing was over-eager in doubling capacity, which lead to 'ludicrous' growth in the diabolical test case as added to cord_test. This CL fixes the doubling for growing shared reps, and tempers CordRepRing growth for non shared capacity to 1.5 instead of 2, which is more inline with a conservative growth we also have in tree cord.
After this change, CordRepRing no longer swamps the heap into the shadow realm, and is in effect reducing the memory used compared to the tree implementation. With a diabolical 5000 bytes growth pattern:
Tree cord: 1523520 bytes
Ring cord: 274232 bytes

Place STL exception functions underneath the ABSL_HAVE_EXCEPTIONS #ifdef.
The STL exception functions are not present in the Android NDK, so Abseil fails to build as part of ANGLE in AOSP. This CL places the various STL exception throwing functions inside #ifdef ABSL_HAVE_EXCEPTIONS blocks so they are removed during Android builds since neither ANGLE nor the NDK support exceptions by default.

Simplify CordRepExternal allocation/deallocation.
I think this can save some memory when `Releaser` is empty and when on platforms where alignof(CordRepExternal) < (default `::operator new` alignment).
We no longer need the API requirement that alignof(Releaser) <= (default `::operator new` alignment).
Also remove another static_assert from a TODO in cord_internal.h and fix some warnings about calling std::move on a forwarding reference.

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.
