Opening a file version-controlled under mercurial causes the following
error:

vc-hg--requirements-understood-p: Symbol’s function definition is void:
cl-set-difference

And the file is not opened.

Reproduction steps:

$ emacs -Q -file <a-hg-controlled-file>

In `vc-hg.el' `cl-lib' is required in compile time.  Requiring it in
evaluation seems to fix the problem.  Below is the patch that fixes the
problem.
