LTTng-UST, the Linux Trace Toolkit Next Generation Userspace Tracer, is
port of the low-overhead tracing capabilities of the LTTng kernel
tracer to user-space. The library "libust" enables tracing of
applications and libraries.

        * Rename trace_mark() API to ust_marker(). Old macros kept for
          slow deprecation.
        * Tracepoint API is now private to UST.
        * Introduction of the TRACEPOINT_EVENT API (work in progress).
          Please use ust_marker() API while we complete TRACEPOINT_EVENT.
        * Privatize many headers which should have always been internal
          to UST. At the moment, only marker.h should be included by
          applications. When the TRACEPOINT_EVENT API will be completed,
          then other headers will be useful for the application
          (tracepoint_event.h, tracepoint.h and, indirectly, probe.h).
        * Markers: merge fixes from LTTng 0.249 into marker.[ch].
        * Add ust/version.h header file, which exports the UST version
        * Move to liburcu 0.6. Update dependencies.
