Bug#950902: projectile: please import upstream v2.1.0

[Nicholas D Steeves <nsteeves@gmail.com>]

Source: projectile
Severity: normal

Hi Sean,

Would you please import upstream v2.1.0 and rebase the patches?  I
don't use git-debrebase and I don't know if a 'gbp pq rebase' will
disrupt your workflow, which is why I'm asking.  See changelog TODO at
commit:601ecc824071ba1d815623b67e27c325c7527683 for the change I'd
like to make after v2.1.0 is imported.

If the patches can be treated as a standard quilt series please let me
know and I'd be happy to merge the tag and rebase the patches myself
:-)


Thanks,
Nicholas

P.S. my motivation for this work is enabling the projectile-based
alternative back-end for Elpy, to allow users who eschew Ivy to have a
fully-functional IDE with comparable performance to the
find-file-in-project methods.
