-- 8becce38c862a044db194a9aea1b505796a46d6f by Abseil Team <absl-team@google.com>: Updates the FixedArray's constructors to be exception safe by preventing double deletions. Also adds exception safety tests for FixedArray to document/enforce the expected behavior. PiperOrigin-RevId: 201964431 -- 794188b401a602b4be97190fb8738066fe1f9ca5 by Derek Mauro <dmauro@google.com>: Fixes for str_format.h documentation. PiperOrigin-RevId: 201951760 -- beae3bdd6eee2cf61101102fddc35ada188f330b by Alex Strelnikov <strel@google.com>: Add numeric_limits specialization for uint128. Turns out numeric_limits is a case where the consensus is that it is okay to specialize for a user defined type. PiperOrigin-RevId: 201944736 -- b2b3444a52b36878ade1ae8801e69932b05fc4f9 by Shaindel Schwartz <shaindel@google.com>: Internal change. PiperOrigin-RevId: 201718662 -- aa924c459922f39caabfc193998c58d0f4981ac0 by Abseil Team <absl-team@google.com>: Typo fix. PiperOrigin-RevId: 201692176 -- bbfcaa7b1af331d9b97c92470608240c5c864fbc by Xiaoyi Zhang <zhangxy@google.com>: Use ABSL_HAVE_ANY/OPTIONAL/VARIANT to conditionally compile out the definition of absl::bad_any_cast, absl::bad_optional_access, absl::bad_variant_access. This would fix the issues where users #include those header directly in C++17 modes. PiperOrigin-RevId: 201683792 GitOrigin-RevId: 8becce38c862a044db194a9aea1b505796a46d6f Change-Id: I60a7ad043136a439d82c374d225a1804016b0509
