[PATCH v7 2/8] dyndbg: remove spaces in pr_debug "gvt: core:" etc prefixes

Taking embedded spaces out of existing prefixes makes them better
class-prefixes; simplifying the extra quoting needed otherwise:
$> echo format "^gvt: core:" +p >control
Dropping the internal spaces means any trailing space in a query will
more clearly terminate the prefix being searched for.
Consider a generic drm-debug example:
# turn off ATOMIC reports
echo format "^drm:atomic: " -p > control
# turn off all ATOMIC:* reports, including any sub-categories
echo format "^drm:atomic:" -p > control
# turn on ATOMIC:FAIL: reports
echo format "^drm:atomic:fail: " +p > control
Removing embedded spaces in the class-prefixes simplifies the
corresponding match-prefix. This means that "quoted" match-prefixes
are only needed when the trailing space is desired, in order to
exclude explicitly sub-categorized pr-debugs; in this example,
"drm:atomic:fail:".
RFC: maybe the prefix catenation should paste in the " " class-prefix
terminator explicitly. A pr_debug_() flavor could exclude the " ",
allowing ad-hoc sub-categorization by appending for example, "fail:"
to "drm:atomic:" without the default " " insertion.
