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.
