Basic Build Improvements:

- Remove Usage of System OpenSSL
- Update OpenSSL from GitHub as Submodule
- Update LuaJit from GitHub as Submodule
- Fixes for gettimeofday()
- Fixes to use x86 intrinsics only on x86
- Rename to wrk2

Integrate Improvements from GitHub:

- Fixes to Script Copy Value Order - PR giltene#113
- Add Fixes for Mutual TLS Authentication - PR giltene#99
- Add Fixes for TLS Ciphers - PR giltene#107
- Add EOF Handling Error - PR giltene#33
- Add JSON Example - PR giltene#51
- Make Rate Optional (use UINT64_MAX) - PR giltene#130
