restore h_errno ABI compatibility with ancient binaries
prior to commit e68c51ac46a9f273927aef8dcebc89912ab19ece, h_errno was
actually an external data object not a macro. bring back the symbol,
and use it as the storage for the main thread's h_errno.
technically this still doesn't provide full compatibility if the
application was multithreaded, but at the time there were no res_*
functions (and they did not set h_errno anyway), so any use of h_errno
would have been via thread-unsafe functions. thus a solution that just
fixes single-threaded applications seems acceptable.
