shallowutil: introduce a helper function isenabled()
This patch introduces a inenabled() function which will check whether
remotefilelog is enabled or not. The function is then also used at all the
places where check whether remotefilelog is enabled or not. The new function
makes code easy to read without need to understand what is the constant involved
and why we are checking repo.requirements.
