[OE-core] [PATCH] scripts/oe-init-bashrc: add more user-friendly oe-setup utility
Jens Rehsack

Mon May 21 15:55:11 UTC 2018
Move scripts/bashrc from meta-jens/scripts to oe-core to share user-friendly
oe builddir management with community. Using this script will help manage
multiple BSPs and targets like perl developers using perlbrew.
Add few missed features as list contained repositories, used layers or other
builddir (in this BSP).
