over with the same event for packages in image.

package.bbclass: add SHLIBSSEARCHDIRS to define where to search for shlib providers

* when package contains some files matching "^.*\.so", but in directory
  not default linker search paths (e.g. /opt/package/bundled-lib/libfoo.so)
  don't register it as libfoo provider, because it's possible that there
  is different package providing libfoo.so in ${libdir} and that would
  be better shlib provider for other packages to depend on
* recipes providing libs intentionally in some other directory can
  define own SHLIBSSEARCHDIRS value

WIP: Add KERNEL_EXTRA_ARGS?
gtk+: Add PACKAGECONFIG for directfb

* building without x11 doesn't work, because it sets default
  gdkbackend to x11 and then requires cairo-xlib to be available
* checking for CAIRO_BACKEND... no
  configure: error: Package requirements (cairo-xlib >= 1.6) were not met:

  No package 'cairo-xlib' found

icecc: don't create unnecessary 'ice' dirs in sysroots when disabled

* parsing ICE_PATH="${@icc_path(bb, d)}" causes "ice" directories
  to be created in every sysroot, that could be a bit confusing for
  people who inherit icecc.bbclass, but disabled it
* shorten ICECC_VERSION="${@icc_version(bb, d)}" path a bit
  by returning sooner when disabled
* remove ICECC_PATH and ICECC_ENV_EXEC from signatures, we assume that
  using icecc doesn't influence the output, so it shouldn't matter when
  user supplies own version of icecc or env script
* always compare ICECC_DISABLED with "1", boolean typed_value isn't used
  because documentation already mentions using empty value to keep icecc
  enabled and that's not valid boolean value when oe.data.typed_value is
  used:
  ERROR: ICECC_DISABLED: Invalid boolean value ''
