perf tools: Add data object to handle perf data file This patch is adding 'struct perf_data_file' object as a placeholder for all attributes regarding perf.data file handling. Changing perf_session__new to take it as an argument. The rest of the functionality will be added later to keep this change simple enough, because all the places using perf_session are changed now.

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.
