[ Merge of http://go/wvgerrit/84647 ] [ Merge of http://go/wvgerrit/84648 ] Replacing most instances of C's NULL with C++'s nullptr. Also changed how a NULL check is performed on smart pointers. They provided an implicit boolean operator for null checks, meaning the underlying pointer does not need to be compared directly (as it was in some places before). Note that clang-format has performed additional changes to some of the test files that have not yet been formatted. Bug: 120602075 Test: Linux and Android unittests Change-Id: I06ddebe34b0ea6dfecedb5527e7e808e32f5269a
