Mark Cord::Clear() with the ABSL_ATTRIBUTE_REINITIALIZES attribute.
This prevents false positives in the clang-tidy check bugprone-use-after-move; it allows Clear() to be called on a moved-from Cord without any warnings, and the Cord will thereafter be regarded as initialized again.

Implement FuzzingBitGen, an adapter which allows existing randomized tests which use absl::BitGenRef to easily integrate with fuzz testing.
I found myself implementing a similar option in our tensorstore project to fuzz test a storage layer and figured that it would be more useful as a common tool with defaults that take the non-random path.
This is similar to the FuzzedDataProvider mechanism which generates random values from a fuzz string, and is used to generate fuzz test inputs, and internally it uses FuzzedDataProvider.
The basic technique used here is to construct mocking lambdas for all of the absl mock distribution configurations, and forwarding the parameters to fuzzing-specific implementations that call into FuzzedDataProvider. The default paths for the distributions are either the bounds or a median value.

Add an attribute to HashtablezInfo which performs a bitwise XOR on all hashes. The purposes of this attribute is to identify if identical hash tables are being created. If we see a large number of identical tables, it's likely the code can be improved by using a common table as opposed to keep rebuilding the same one.

These lines could theoretically have overflowed in cases of very large stack

Don't call win32 APIs for UWP builds
symbolize.cc is including symbolize_win32.inc for all Windows builds,
including UWP builds. However, UWP doesn't have access to win32 APIs, so
it should instead include symbolize_unimplemented.inc.
This allows the necessary functions to still exist and be called, but
the win32 calls are not made.

Remove incorrect claims of HASH_NAMESPACE support in Abseil hash.
The documentation presently claims that absl::Hash will look for legacy hashers (e.g, in the __gnu_cxx namespace) as controlled by the HASH_NAMESPACE preprocessor define, but this has never been true.
(Vestigial support for this appears in the form `ABSL_INTERNAL_LEGACY_HASH_NAMESPACE`, but this is not a supported extension point, as indicated by the use of `INTERNAL` in the name.)

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.
