Add libavb lib (3rd party library from AOSP), that implements support of AVB 2.0. This library is used for integrity checking of Android partitions on eMMC. libavb was added as it is and minimal changes were introduced to reduce maintenance cost, because it will be deviated from AOSP upstream in the future. Changes: - license headers changed to conform SPDX-style - avb_crc32.c dropped - updates in avb_sysdeps_posix.c/avb_sysdeps.h For additional details check [1] AVB 2.0 README.
