Every dtrace/systemd probe also include a libvirt log message.
These are logged at level DEBUG currently, which means if you
want to see all probes they are drowned by the rest of the
DEBUG messages. Since we don't really use the INFO log level
for much, it seems reasonable to suggest we log all probes at
level INFO.
As part of the goal to get away from doing string matching on
filenames when deciding whether to emit a log message, turn
the virLogSource enum into a struct which contains a log
"name". There will eventually be one virLogSource instance
statically declared per source file. To minimise churn in this
commit though, a single global instance is used.

The dtrace probe macros rely on the logging API. We can't make
the internal.h header include the virlog.h header though since
that'd be a circular include. Instead simply split the dtrace
probes into their own header file, since there's no compelling
reason for them to be in the main internal.h header.
