- Completely removed config.h generation file, as it was not used
anywere in the code
- Removed all the old build files and switched to CMake (3.0+)
- As tl-parser only uses zlib for crc32, removing the dependency makes
the CMake file easier to maintain and makes the code building
without third party code. The crc32 implementation was taken from
abb3e47a98.
