If strlist_config.dirname is present, the strlist__new() tries to load
stirngs from dirname/list file first but if it failes it falls back to
add 'list' as string. But sometimes it's not desired so adds new
file_only field to prevent it.

So, if we have an strlist equal to:
"file,close"
And we call it as:
struct strlist_config *config = { .dirname = "~/strace/groups", };
struct strlist *slist = strlist__new("file, close", &config);
And we have:
$ cat ~/strace/groups/file
access
open
openat
statfs
Then the resulting strlist will have these contents:
[ "access", "open", "openat", "statfs", "close" ]
This will be used to implement strace syscall groups in 'perf trace',
but can be used in some other tool, thus being implemented in 'strlist'.

So that we can pass more info to strlist__new() without having to change
its function signature, just adding entries to the strlist_config struct
with sensible defaults for when those fields are not specified.

As suggested by tglx, 'self' should be replaced by something that is

Replaces the direct use of rbtree code with the rblist API. In the end
the patch is a no-op on strlist functionality; the API for strlist is
not changed, only its implementaton.

Add for_each iteration macros for strlist. This patch
introduces strlist__for_each() and strlist__for_each_safe(),
both are similar to list_for_each() and list_for_each_safe().

The strlist__entry method allows accessing strlists like an
array, will be used in the 'perf report' to access the first
entry.
We now keep the nr_entries so that we can check if we have just
one entry, will be used in 'perf report' to improve the output
by showing just at the top when we have just, say, one DSO.
While at it use nr_entries to optimize strlist__is_empty by not
using the far more costly rb_first based implementation.

The tools/perf/util/rbtree.c copy already drifted by three
csets:
4b324126e04c6011781116c047add3
So remove the copy and use the lib/rbtree.c directly, sharing
the source code while still generating a separate object file,
since tools/perf uses a far more agressive -O6 switch.
