Subject: [PATCH 1/5] perf tools: Remove repipe argument from perf_session__new()
The repipe argument is only used by perf inject and the all others
passes 'false'. Let's remove it from the function signature and add
__perf_session__new() to be called from perf inject directly.
This is a preparation of the change the pipe input/output.
