Subject: sanity.bbclass: bblayers.conf should be updated automatically
X-Git-Tag: rev_ivi_2015_02_04~15351
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4d583c956b3699c97ea4747b1cab87b7fc94532a;p=scm%2Fbb%2Ftizen-distro.git

sanity.bbclass: bblayers.conf should be updated automatically

- add check_bblayers_conf bitbake function which does the bblayers.conf
v4 -> v5 update if necessary (every layer should make its specific
bblayers.conf upgrades appending to the check_bblayers_conf function)
- we ask the user to re-run bitbake because we can't trigger reparsing
without being invasive

[YOCTO #3082]
