Subject: scripts/getver.sh: try to get branch/upstream automatically
X-Git-Tag: v17.01.0-rc1~2082
X-Git-Url: http://git.openwrt.org/?p=openwrt%2Fopenwrt.git;a=commitdiff_plain;h=4eb5aad667bc838b8ebb80c9b970d6bb2f6c013d;hp=efa1960abb390d696704d029507dff671cc271fd

scripts/getver.sh: try to get branch/upstream automatically

Instead of assuming master is the current branch and origin the right
upstream, try to get both dynamically. If the current branch is not
tracking any upstream, use the origin of the master branch.
