[RFC][PATCH 4/8] events: Update tools/lib/events to work with perf

[Steven Rostedt]

From: Steven Rostedt <srostedt@xxxxxxxxxx>

Some of the util functions of libparsevent.a conflict with perf,
such as die(), warning() and others. Move them into event-util.h
that is not included by the perf tools.

Also, as perf compiles with 'bool' the filter_arg->bool needs to
be renamed to filter_arg->boolean.
