PATCH COMMITTED: C++ changes for include directory

- Subject: PATCH COMMITTED: C++ changes for include directory
This patch changes three header files in the include directory to be C++
ready. I added extern "C". I changed ansidecl.h to handle C++ like ISO
C with regard to whether prototypes are supported and the like, and to
not define "inline" as a macro when compiling with C++. I added a
header guard macro to dyn-string.h. While I was looking at the files, I
updated the copyright notice to include the years when they were
changed.
Bootstrapped on x86_64-unknown-linux-gnu. Committed to mainline.

* ansidecl.h: Add extern "C" when compiling with C++. Treat C++
the way we treat an ISO C compiler. Don't define inline as a
macdro when compiling with C++.
* dyn-string.h: Add header guard DYN_STRING_H. Add extern "C"
when compiling with C++.
* fibheap.h: Add extern "C" when compiling with C++.
