The libvirtd daemon had a few crude system tap probes. Some of these were broken during the RPC rewrite. The new modular RPC code is structured in a way that allows much more effective tracing. Instead of trying to hook up the original probes, define a new set of probes for the RPC and event code. The master probes file is now src/probes.d. This contains probes for virNetServerClientPtr, virNetClientPtr, virSocketPtr virNetTLSContextPtr and virNetTLSSessionPtr modules. Also add probes for the poll event loop. The src/dtrace2systemtap.pl script can convert the probes.d file into a libvirt_probes.stp file to make use from systemtap much simpler. The src/rpc/gensystemtap.pl script can generate a set of systemtap functions for translating RPC enum values into printable strings. This works for all RPC header enums (program, type, status, procedure) and also the authentication enum The PROBE macro will automatically generate a VIR_DEBUG statement, so any place with a PROBE can remove any existing manual DEBUG statements. * daemon/libvirtd.stp, daemon/probes.d: Remove obsolete probing * daemon/libvirtd.h: Remove probe macros * daemon/Makefile.am: Remove all probe buildings/install * daemon/remote.c: Update authentication probes * src/dtrace2systemtap.pl, src/rpc/gensystemtap.pl: Scripts to generate STP files * src/internal.h: Add probe macros * src/probes.d: Master list of probes * src/rpc/virnetclient.c, src/rpc/virnetserverclient.c, src/rpc/virnetsocket.c, src/rpc/virnettlscontext.c, src/util/event_poll.c: Insert probe points, removing any DEBUG statements that duplicate the info
