tools lib traceevent, perf tools: Move struct tep_handler definition in a local header file

2018-10-08T18:05:37Z

As traceevent is going to be transferred into a proper library, its local data should be protected from the library users. This patch encapsulates struct tep_handler into a local header, not visible outside of the library. It implements also a bunch of new APIs, which library users can use to access tep_handler members.

tools lib traceevent: Separate out tep_strerror() for strerror_r() issues

2018-10-08T17:30:45Z

While working on having PowerTop use libtracevent as a shared object library, Tzvetomir hit "str_error_r not defined". This was added by commit c3cec9e68f12d ("tools lib traceevent: Use str_error_r()") because strerror_r() has two definitions, where one is GNU specific, and the other is XSI complient. The strerror_r() is in a wrapper str_error_r() to keep the code from having to worry about which compiler is being used. The problem is that str_error_r() is external to libtraceevent, and not part of the library. If it is used as a shared object then the tools using it will need to define that function. I do not want that function defined in libtraceevent itself, as it is out of scope for that library. As there's only a single instance of this call, and its in the traceevent library's own tep_strerror() function, we can copy what was done in perf, and create yet another external file that undefs _GNU_SOURCE to use the more portable version of the function. We don't need to worry about the errors that strerror_r() returns. If the buffer isn't big enough, we simply truncate it.

tools lib traceevent: Add prefix tep_ to enum filter_trivial_type

2018-09-19T20:30:46Z

In order to make libtraceevent into a proper library, variables, data structures and functions require a unique prefix to prevent name space conflicts. That prefix will be "tep_". This adds prefix tep_ to enum filter_trivial_type and all its members.
