69b5d0b2a5adb49a53e51f9da6848eaa484242fe by Derek Mauro <dmauro@google.com>:

Changes the absl::Duration factory functions to disallow types that
are convertible to int or double, instead requiring that the argument
itself is indeed an integer or a floating-point number. This will
prevent callers from passing arguments, such as std::atomic<T>.

This change is an API break. Information and a tool to fix issues
can be found at
https://abseil.io/docs/cpp/tools/upgrades/duration-conversions

Make ctrl_t be an enum class.

This adds type safety, and also when strict aliasing is enabled, the compiler will know that control bytes can't alias non-control bytes.

Also make H2() return h2_t.

7e537aabec1c255d6e7c9d21232c597c1c2077bf by Evan Brown <ezb@google.com>:

Add some missing `const` keywords to ctrl_t* function parameters.

da53ac6d91cabd951e81dd0a145e1e52b918955f by Martijn Vels <mvels@google.com>:

Change Seek and InitOffset to return nullptr instead of assert / fail.

This makes it consistent with the rest of the API (Next, Previous, Skip) and hardens it against invariants that are harder (or less likey) to be upheld correctly by the caller.

90ce5872406df2b7f4c428683741dc13a572267e by Abseil Team <absl-team@google.com>:

b30a2fd777f12a04a4d512f37a34614b0d05ce99 by Derek Mauro <dmauro@google.com>:

Skip length checking when constructing absl::string_view from std::string.
The length check causes unnecessary code bloat.
