1676797 - Replace MOZ_MUST_USE with [[nodiscard]] in docshell

Status: RESOLVED FIXED

(Core :: DOM: Navigation, task, P3)

Description

[Chris Peterson [:cpeterson]]

The MOZ_MUST_USE macro is defined as clang's and gcc's nonstandard __attribute((warn_unused_result))__. Now that we compile as C++17 by default (bug 1560664), we can replace MOZ_MUST_USE with C++17's standard [[nodiscard]] attribute.
