This is particularly useful on operating systems that don't ship
Perl as part of the base system (eg. FreeBSD) while still working
just as well as it did before on Linux.
In one case (src/rpc/genprotocol.pl) the interpreter path was
missing altogether.

The generated output is dependent on perl hashtable ordering, which
gives different results for i686 and x86_64. Fix this by sorting
the hash keys before iterating over them

The naming used in the RPC protocols for the LXC monitor and
lock daemon confused the script used to generate systemtap
helper functions. Rename the LXC monitor protocol symbols to
reduce confusion. Adapt the gensystemtap.pl script to cope
with the LXC monitor / lock daemon naming conversions.
This has no functional impact on RPC wire protocol, since
names are only used in the C layer

The cfg.mk file rule to check for tab characters was not
applied to perl files. Much of our Perl code is full of
tabs as a result. Kill them, kill them all !
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/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
