Add missing File APIs

Volume.fopen() method mimics Python's built-in File object
Example:
    with v.fopen("/path/to/file", "w") as f:
        f.write("hello world")
fopen() returns a File object.

Volume.open() method mimics os.open() Python API.
Example:
    with File(v.open("/path/to/file", os.O_WRONLY | os.O_CREAT)) as f:
        f.write("hello world")

open() returns the raw glfd that (as of today) needs to be passed to File class.
In future, more APIs will be provided to directly use the glfd returned.

Unlike their C versions, these methods do not return
anything on success. If methods fail, exceptions are raised.

Added docstrings to methods in File class.
