perf tools: Add perf_data_file__write interface
Adding perf_data_file__write interface to centralize output to files. The function prototype is: ssize_t perf_data_file__write(struct perf_data_file *file, void *buf, size_t size); Returns number of bytes written or -1 in case of error. NOTE: Also indenting 'struct perf_data_file' members, no functional change done.
