Instead of passing the address of a KernelArgumentBlock to libc.so for initialization, use __loader_shared_globals() to initialize globals. Most of the work happened in the previous CLs. This CL switches a few KernelArgumentBlock::getauxval calls to [__bionic_]getauxval and stops routing the KernelArgumentBlock address through the libc init functions. Bug: none Test: bionic unit tests Change-Id: I96c7b02c21d55c454558b7a5a9243c682782f2dd
