This change adds #include <string> to files currently including "base/strings/string16.h". This prepares these files for the planned removal of the base::string16 alias. In order to adhere to the style guide [1] the following logic was performed: * Insert into an existing block of C++ STL includes, if possible * Else insert `#include <string>` followed by a newline before the first #include "some_header.h" line that is not referring to a matching header (only relevant for implementation and test files) [1] https://google.github.io/styleguide/cppguide.html#Names_and_Order_of_Includes Bug: 1184339 Change-Id: I96660fec3fff0192d53e9728bbbae86228a52c58 Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/2749296 Commit-Queue: Jan Wilken Dörrie <jdoerrie@chromium.org> Owners-Override: Jan Wilken Dörrie <jdoerrie@chromium.org> Reviewed-by: Peter Kasting <pkasting@chromium.org> Cr-Commit-Position: refs/heads/master@{#861966}
