pg_ls_dir_* will now skip (no longer show) symbolic links, same as other
non-regular file types, as we advertize we do since 8b6d94cf6.  That seems to
be the intented behavior, since irregular file types are 1) less portable; and,
2) we don't currently show a file's type except for "bool is_dir".

pg_stat_file will now 1) show metadata of links themselves, rather than their
target; and, 2) specifically, show links to directories with "is_dir=false";
and, 3) not error on broken symlinks.

Commits look fine to me, but I hate the new target names... Luckily, 
I just use plain ninja, so I don't interact with that.

My only comment is that you could reverse the logic and save yourself an 
indentation.

- if len(targets_info_byname[name]) > 1:
+ if len(targets_info_byname[name]) <= 1:
+     continue

But whatever you want.
