General

Top level lib directory tidy up
- build scripts and header file left at the top level
- lib/x86_64 directory created
- files requiring compilation moved from lib/include
Symbols not stripped from static library at installation
API name changes and unification
- mapping provided for backwards compatibility
NASM version check in the build script
CET enabling in the build scripts
