Infrastructure changes:

 o More prep work to support Intel PT: (Adrian Hunter)
   - Polishing 'script' BTS output
   - 'inject' can specify --kallsym
   - VDSO is per machine, not a global var
   - Expose data addr lookup functions previously private to 'script'
   - Large mmap fixes in events processing

 o Fix build on gcc 4.4.7 (Arnaldo Carvalho de Melo)

 o Event ordering fixes (Jiri Olsa)

 o Include standard stringify macros in power pc code (Sukadev Bhattiprolu)
