largefiles: testcase to simulate inter-user clone on local machine

largefiles: make the store primary, and the user cache secondary This uses the now-properly-named functions and methods from the previous patch to actually deliver the desired behavior

largefiles: rename functions and methods to match desired behavior The original intent was that the largefiles would primarily be in the repository, with the global cache being only that--a cache. The naming conventions and actual intent have both strayed. In this first patch, the naming conventions are switched to match the actual intent, as are the configuration options.

largefiles: fix some badly named function parameters overrides.py contains several functions that temporarily override scmutil.match(), which always takes a changectx object as the first parameter. But these overrides name that parameter either 'repo' or 'ctxorrepo', which is misleading. So rename them to 'ctx' and remove the special type-sensitive handling of the one called 'ctxorrepo'.

largefiles: tidy imports - no need to defensively import scmutil - remove duplicate - unwrap non-long line
