Subject: [PATCH 3/3] doc: Sphinxify the tracepoint docbook

Convert the tracepoint docbook template to RST and add it to the core-api
manual.  No changes to the actual text beyond the mechanical formatting
conversion.

+Introduction
+============
+
+Tracepoints are static probe points that are located in strategic points
+throughout the kernel. 'Probes' register/unregister with tracepoints via
+a callback mechanism. The 'probes' are strictly typed functions that are
+passed a unique set of parameters defined by each tracepoint.
+
+From this simple callback mechanism, 'probes' can be used to profile,
+debug, and understand kernel behavior. There are a number of tools that
+provide a framework for using 'probes'. These tools include Systemtap,
+ftrace, and LTTng.
+
+Tracepoints are defined in a number of header files via various macros.
+Thus, the purpose of this document is to provide a clear accounting of
+the available tracepoints. The intention is to understand not only what
+tracepoints are available but also to understand where future
+tracepoints might be added.
+
+The API presented has functions of the form:
+``trace_tracepointname(function parameters)``. These are the tracepoints
+callbacks that are found throughout the code. Registering and
+unregistering probes with these callback sites is covered in the
+``Documentation/trace/*`` directory.
