PiperOrigin-RevId: 237088193 -- d271ffdd3f450f817f6d30e98ff39d439aaf3a98 by Abseil Team <absl-team@google.com>: Make symbolizer examine any mapping with read+exec permission regardless of 'w' bit. PiperOrigin-RevId: 237056461 -- af315f8306d36a7367a452fd0b58cafdbf20719d by Abseil Team <absl-team@google.com>: Switch comments referencing base:: CondVar and Mutex to absl::. PiperOrigin-RevId: 236917884 -- c624d5d1c0bdb917bff5e651ba40599472f84e0e by Gennadiy Rozental <rogeeff@google.com>: Internal change PiperOrigin-RevId: 236898300 -- 3cdc82429af964846d1152f49148abc61d196a4b by Samuel Benzaquen <sbenza@google.com>: Make the `long double` overload if AbslHashValue a template to avoid invalid conversions with implicit operators. This overload was never meant to capture anything other than `long double` and any current caller to it that wasn't a `long double` is potentially a bug. In particular, any type with an implicit `bool` conversion is calling this overload instead of trying to find a hash<> specialization, thus causing pretty bad hash behavior.
