libbinder: Support unaligned reads/writes in Parcel.cpp Parcel words have a 4 byte alignment. Calls to readAligned and writeAligned with larger types, e.g., binder_uintptr_t from readPointer, would crash with an UBSan violation. This fixes those crashes by using memcpy() to copy unaligned values and require that all such values are trivially copyable. Bug: 2002930 Test: atest binderRpcTest Change-Id: Id9430ca85a7d9ae8e9df7328ef7f64fa432233a6
