[OE-core] [PATCH 0/5] shlibs providers improvements

[Martin Jansa]

Fixes for [YOCTO #4628]

Richard had few more ideas to improve it even more, but this is good start.

Most important changes:
* PRIVATE_LIBS aren't duplicitly added to RDEPENDS (when recipe provides
  own libfoo it shouldn't get runtime dependency on global libfoo shlib provider)
* warning is shown for undeterministic providers (multiple packages
  recorded to provide the same library) - recipe maintainers can decide
  if such library should be considered private or make sure that only one
  package is built (most common case are gst plugins where 0.10 and 1.* provide
  the same gst modules, but as long as nobody tries to linke directly to some
  gst plugin we shouldn't list them as shlib providers).
* list files which require given shlib, often I was surprised to see that
  something got runtime dependency on libfoo, showing which binary is linked to
  it makes it easier to debug when you have only log.do_package and package
  directory is already gone (e.g. analyzing test-dependencies.sh script outputs)

The following changes since commit 8163854adf87ac42a8f08ee25685d0ce1efb4724:
