Leave two older ones behind as compile options for education. * tapsets.cxx (*): Reworked all probe registration code, moving it from derived_probes into derived_probe_groups. Shrunk output code. Temporarily disabled probe timing and perfmon/mark probes. (dwflpp): Use offline reporting, so that module matching and relocation is performed at run time. (dwarf_query): Remove flavour logic, now supplanted by other duplicate elimination code. (dwarf_derived_probe): Reworked construction, centralized module/section/offset computations. * tapsets.h (all_session_groups): New little helper. * main.cxx (main): For pass-2 message, print number of embeds too. * systemtap.spec.in: Add a "BuildRequires: dejagnu" for make check. * configure.ac: Bump version to 0.5.11. * configure: Regenerated.
