Message : Make path utils return std::string. This avoids potential issues with returning local variables. It also solves potential threading conflicts by returning the string value instead of a pointer. The code should be optimized with RVO with a modern c++ compiler. Bug: angleproject:2601 Change-Id: I8a01702d2675a17dd060f27920105efab0c49454 Reviewed-on: https://chromium-review.googlesource.com/c/1415910 Reviewed-by: Kai Ninomiya <kainino@chromium.org> Reviewed-by: Geoff Lang <geofflang@chromium.org> Commit-Queue: Jamie Madill <jmadill@chromium.org>
