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.
