[x264-devel] Simplify inclusion of x264.h in C++ projects

[Mark Webster]

x264 | branch: master | Mark Webster <mark.webster at gmail.com> | Wed Aug  5 04:28:17 2015 +0100| [e86f3a1993234e8f26050c243aa253651200fa6b] | committer: Anton Mitrofanov

Simplify inclusion of x264.h in C++ projects

Name all structs to support forward declarations.
Add a conditional extern "C" wrapper in x264.h itself instead of having to
specify it in every location where it's included.
