Down-integrate from internal code base.

Check HAVE_CONFIG_H before including "config.h"

Now the Build tool needs to define -DHAVE_ZLIB and -DHAVE-PTHREAD rather
than providing a config.h

- Make pbconfig.h a manually written file to handle hash conditions
  according to platform related macros.
- Remove #include "config.h" from source code.
- Changed the configure.ac and Makefile.am to pass down the macros.
- Change cmake to pass down the the macros.
