[PATCH 56/57] perf trace: Wire up strarray__strtoul_flags()

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>

Now anything that uses STRARRAY_FLAGS, like the 'fsmount' syscall will
support mapping or-ed strings back to a value that can be used in a
filter.

In some cases, where STRARRAY_FLAGS isn't used but instead the scnprintf
is a special one because of specific needs, like for mmap, then one has
to set the ->pars to the strarray. See the next cset.
