Move from CyaSSL to wolfSSL

This patch lets libwebsockets use the lastest version of wolfSSL (the new name for CyaSSL).
The reason for the patch is that allthough wolfSSL provides compatibility headers for (old) projects using CyaSSL,
these are incomplete and do not work for libwebsockets.

The patch also fixes a typo in CMakeLists.txt where CYASSL_LIBRARIES was added to include_directories() instead of CYASSL_INCLUDE_DIRS.
