Porting pylint to golang.

Initial strategy is to call python code to build ast and provide details then use checkers written in go to run over them and produce reports

Notes

• We build ast in python, and we tokenize the code in python
• Remember, tokenize uses ast node from built by astroid, which underneath is just bufferedstream: this is what utils.tokenize_module does with ast_node in PyLint

ipdb> ast_node.stream                                                                                                                                                           
<bound method Module.stream of <Module.foo l.0 at 0x7f70b9493080>>
ipdb> ast_node.stream()                                                                                                                                                         
<_io.BufferedReader name='/home/melvault/Documents/programs/read_pylint/foo.py'>
ipdb> ast_node.stream().readline                                                                                                                                                
<built-in method readline of _io.BufferedReader object at 0x7f70b9e32728>
ipdb> tokens   

• we also need tokenize to detect encoding of the file we are trying to read for some reason

astroid.builder.py
def open_source_file(filename):
    with open(filename, "rb") as byte_stream:
        encoding = detect_encoding(byte_stream.readline)[0]
    stream = open(filename, "r", newline=None, encoding=encoding)
    data = stream.read()
    return stream, encoding, data
