This is a merge from the Widevine repo of http://go/wvgerrit/117311 Update backwards compatibility builds http://go/wvgerrit/117423 Restrict maximum size of key id To protect from out-of-memory found by fuzz testing. http://go/wvgerrit/117683 Generation number should wrap The master generation number should wrap around on overflow. This means that we cannot use less than to check for a skew of 1. http://go/wvgerrit/119232 Replace 0 with nullptr Bug: 176234903 Bug: 184866351 Bug: 161243686 Test: ran unit tests (CL affects test code only) Merged-In: Ie787bcf9c66a7605700c3dc29a8aa16406926ce3 Change-Id: I2b02a36a70a0920f31ffc00de102a23516d4b20e
