This has no effect on user code or backward compatibility. It moves the in-tree public api header libwebsockets.h from ./lib to ./include, and introduces a dir ./include/libwebsockets/ The single public api header is split out into 31 sub-headers in ./include/libwebsockets. ./include/libwebsockets.h contains some core types and platform adaptation code, but the rest of it is now 31 #include <libwebsockets/...> At install time, /usr/[local/]include/libwebsockets.h is installed as before, along now with the 31 sub-headers in ...include/libwebsockets/ There's no net effect on user code. But the api header is now much easier to maintain and study, with 31 topic-based sub headers.
