Revert removal of some structured bindings and selection statements with initializers.

Revert part of cl/387364180.  At that time these C++17 features were banned in
Chromium and did not compile.  They have been allowed since then, see:

* structured bindings

* selection statements with initializers:

Note that the initializer cannot be moved back into the if statement in
OgHttp2Session::ResumeStream() because a line accessing `it` has been added
afterwards since.

QUICHE stands for QUIC, Http/2, Etc. It is Google‘s production-ready implementation of QUIC, HTTP/2, HTTP/3, and related protocols and tools. It powers Google’s servers, Chromium, Envoy, and other projects. It is actively developed and maintained.

There are two public QUICHE repositories. Either one may be used by embedders, as they are automatically kept in sync:

To embed QUICHE in your project, platform APIs need to be implemented and build files need to be created. Note that it is on the QUICHE team's roadmap to include default implementation for all platform APIs and to open-source build files. In the meanwhile, take a look at open source embedders like Chromium and Envoy to get started:

QUICHE is only supported on little-endian platforms.
