Fix git checkout for branches and commits
Replace 'git checkout -f -B $BRANCH origin/$BRANCH && \' in all
Dockerfiles that accept branch variables ($OSMO_TTCN3_BRANCH,
$OSMO_MGW_BRANCH, ...) with the following:
git checkout $BRANCH && \
(git symbolic-ref -q HEAD && git reset --hard origin/$BRANCH || exit 1); \
This allows using branch names and commit hashes in the $BRANCH
variables. Using commits is needed for the bisect script added in [1].
The second line ("(git symbolic...") checks if we are in detached HEAD
state after the checkout, and if we are not, pulls in all new commits
from origin/$BRANCH. Note that it ends in ';' instead of '&&', because
the command in the next line should be executed even if
"git symbolic-ref" does not exit with 0 (detached HEAD state).
Here is an example, to illustrate that the new command does the right
thing. Clone a repository and be 50 commits behind origin/master:
$ git clone "https://git.osmocom.org/osmo-mgw"
$ cd osmo-mgw
$ git reset --hard origin/master~50
With BRANCH="master":
$ git checkout master && \
(git symbolic-ref -q HEAD && git reset --hard origin/master || exit 1); \
echo "done"
Already on 'master'
...
done
$ git status
Your branch is up-to-date with 'origin/master'.
With BRANCH="85978d":
$ git checkout 85978d && \
(git symbolic-ref -q HEAD && git reset --hard origin/85978d || exit 1); \
echo "done"
Note: checking out '85978d'.
...
done
$ git status
HEAD detached at 85978dad

than master, and pulling in new commits from master

pulling in new commits from master
