* [absl] Rename `absl::internal::identity` to `absl::internal::type_identity`Gravatar Lawrence Wolf-Sonkin2023-12-28
| | | | | | | | * Also does this for `absl::internal::identity_t` which is now `absl::internal::type_identity_t` * This is clearer naming as this is a backfill of `std::type_identity` (the identity type), and not `std::identity` (the identity function) PiperOrigin-RevId: 594316002 Change-Id: I5fb8cf7e3d07c1bc736cbecd202e7d556b6ea33e

The best we get is "byte representation". * Removes a circular defition of "bitcast" as itself, and instead explains what it does. * Removes the mathism "for some values of", which is probably not totally accessible to a general audience, and in any case needless verbiage. * Fixes comments in the example. * Replaces some colloquialisms with simpler, more direct language.

PiperOrigin-RevId: 284780736 -- 28e76c08ea7185a7ff9f4e0e02ae565fbbf7980f by Greg Falcon <gfalcon@google.com>: Implementation detail change. Introduce ABSL_NAMESPACE_BEGIN and _END annotation macros which indicate the beginning and end of a `namespace absl` scope. Currently these do nothing, but they will be used to inject an inline namespace for LTS builds (to avoid symbol collisions against other Abseil versions). These macros should not be used by end users, because end users should never write `namespace absl {` in their own code. This CL applies these annotations to all code under //absl/base/. The rest of Abseil will be annotated in this way in follow-up CLs.

Ideally, the constraints should depend on std::is_trivally_copyable, but a combination of supported configurations and lack of intrinsic support for bit_cast makes this not currently feasible. In a future change we should introduce more proper preprocessor branching and workarounds to better emulate the trait.
