threads: introduce util/threadnames, refactor thread naming
This work is prerequisite to attaching thread names to log lines and deadlock debug utilities. This code allows setting of an "internal" threadname per thread on platforms where thread_local is available. This commit also moves RenameThread() out of a more general module and adds a numeric suffix to disambiguate between threads with the same name. It explicitly names a few main threads using the new util::ThreadRename().
