[PATCH] Process new C++17 and C++20 headers with Doxygen

[-- Attachment #1: Type: text/plain, Size: 242 bytes --]

This won't do anything by default, because __cplusplus is set to 201402L
when Doxygen runs. If/when that changes, these headers should be
processed.

	* doc/doxygen/user.cfg.in (INPUT): Add new C++17 and C++20 headers.

Committed to trunk.
