use wrapper headers to hide most namespaced/internally-public symbols

not all prefixed symbols can be made hidden. some are part of ABI-compat (e.g. __nl_langinfo_l) and others are ABI as a consequence of the way copy relocations for weak aliases work in ELF shared libraries. most, however, can be made hidden. with this commit, there should be no remaining unintentionally visible symbols exported from libc.so.
