Previously we save the current commit hash before running lintstack.
This is no problem for Jenkins but not very friendly if we run
lintstack locally. Every time after it's done, git is in detached
HEAD mode. This patch remembers the current branch name and
automatically go back to the branch if available. Otherwise we fall
back to the commit hash.

Some patches in gerrit depend on other patches that are not yet
approved, i.e. not yet landed on master. In this patch lintstack
deals with these cases by currectly generating the right commit
to compare against to further reduce pylint errors.

Add a new silent test target lintstack based on pylint in Jenkins.
lintstack will compare the pylint errors between HEAD and HEAD~1,
filter out known false positives and report violations in pylint
original parseable format for Jenkins to consume.
