WritableFileWriter: default buffer size equal min(64k,options.writabl?

Browse Source 
Summary:
?e_file_max_buffer_size)

If we overwrite WritableFile and has a buffer which has the same
function of buf_. We hope remove the cache function of
WritableFileWriter. So using options.writable_file_max_buffer_size = 0
to disable cache function.
