Bug#709003: lintian: Evaluation of current experimental tags

[Niels Thykier <niels@thykier.net>]

Package: lintian
Version: 2.5.12
Severity: normal
Control: block -1 by 699059

Started at [1], but seeing as I haven't had time to deal with it yet I
fear it might "disappear" in the depths of my mailbox.

I have tried to summarize the current state from the debate on the
list, which I believe to be:

 P python(3)-depends-but-no-python(3)-helper
 u package-contains-no-arch-dependent-files
   - has false-positives on "pkg [linux-any]" dependencies.
 d package-contains-broken-symlink
   - Suggested that we keep it until #699059 is fixed.
 u duplicate-files
   - suggested pedantic/wild-guess (NB: partly done, I think)
   - avoid triggering on doxygen stuff (or small files in usr/share/doc)
 u embedded-pear-module
   - need talk with php/pear maintainers to confirm/improve accuracy
     and expanding the detection list.
 ? shlib-calls-exit
   - There was some disagreement here, but it seems to have ended in favor
     of keeping the tag.  Possibly with whitelisting some known cases, e.g.
     Apache modules?

Legend:
  p, P -> "Promote(d) to non-experimental as-is"
  d, D -> "Drop(ped) the tag"
  u, U -> "Update(d) the tag and then promote/re-evaluate"
  ?    -> "Needs more info"

(Upper case means it has already been done. i.e. P is "already
promoted", where as p is "intend to promote as-is").
