- Added __set_h_errno() and __get_h_errno() functions.

- The thread-safe library now tries to enable bsdsocket.library base
  sharing and attempts to make the TCP/IP stack call the local
  __set_errno() and __set_h_errno(), so that any Process calling
  the library functions will get a chance to see proper error
  codes. Whether any of these features could be enabled can be tested
  through two global variables __can_share_socket_library_base and
  __thread_safe_errno_h_errno which are defined in <dos.h>. Note that
  for both features to work you will need the Roadshow bsdsocket.library
  version 4.275 or higher.
