[2/2] tools/lib/traceevent: make few libtraceevent internal variables to be per thread

Commit Message

Tzvetomir Stoyanov Nov. 30, 2018, 1:13 p.m. UTC

This patch continues the effort to transform libtraceevent
into a thread safe library. It converts input_buf, input_buf_ptr
and input_buf_siz internal variables to be thread specific. This
buffer is not related to a specific tep context. It is used
internally by the library during the parsing of various strings.
