[OE-core] [PATCH v2 00/25] Fix for #7040 - Support for /usr merge

[Amarnath Valluri]

This set of patches implements the long-standing feature - merging of /bin,
/sbin, /libs to their /usr counterparts.

It introduces a 'usrmerge' DISTRO_FEATURE, when it's enabled:
     - other than native all base paths(base_{bin,sbin,lib}dir) points to
       ${exec_prefix}/{bin,sbin,lib}
     - base-files package adds the needed root links(/bin, /sbin, /lib{32,64})
       points to /usr counterparts
     - As most of shell scripts refer "#!/bin/{sh,bash}" inside script, so makes
       sure that get added to RPROVIDES_ list by those packages to satisfy the
       build dependencies.

The assumption is that no recipe uses hard coded paths in recipes where
pre-defined bitbake configuration variables are available. I have fixed quite
many recipes that i found which violates this assumption.

I have tested this change on core-minimal, sato, windriver cube-desktop and
intel-iot-refkit image builds. And i would prefer to run autobuilder tests prior
to merging.

Changes in v2:
 - Moved root links creation out from 'base-files' to pre-rootfs.
 - Fixes to lsb, lttng-modules recipes., that are failed in autobuilder tests.
 - Added insane check to usrmerge feature.
 - Fixed typos in commit messages.
