- Change formatting standard to Cpp11. Main difference is not having the space between two closing >> for nested templates. We don't choose c++14, because older versions of clang-format (version 9 and earlier) don't know this value yet, and it doesn't make a difference in the formatting. - Apply clang-format to all (non generated) internal source files. - Manually fix some code sections (clang-format on/off) and c-strings - Exclude some embedded external files with very different formatting (gtest/gmock) - Add script to format all source files Change-Id: Ic6cea41575ad6e37c9e136dbce176b0d505dc44d
