Message:

Make some libc and libposix headers usable in C++

These headers either get included from standard C++ headers,
or are standard themselves, which means any unnamespaced nonstandard
identifiers are a problem. This commit attempts to fix those
issues, and removes hacks previously used in libcpp to work around it.
