[PATCHv2 0/7] perf tools: Add data file write interface

[Jiri Olsa <jolsa@redhat.com>]

hi,
adding perf_data_file__write function to centralize
output file writes. Using it in record and inject
commands.

v2 changes:
  - changes for readn function, suggested by Ingo
  - added writen function, suggested by Arnaldo
  - spliting record change into 2 separated patches
  - omiting some unnecessary changes in the inject change
 
thanks,
jirka
