cmdutil: add a hook for making custom non-follow log file matchers

This will be used by largefiles (and basically only by largefiles) in an
upcoming patch.

largefiles: drop setting lfstatus in overridelog (issue4334)

lfstatus should only be True for operations where we want standins to be
printed out. We explicitly do not want that for historical operations like log.
Other historical operations like hg diff -r A -r B don't print out standins
either.

This is required to fix issue4334, but doesn't fix anything by itself. That's
why there aren't any tests accompanying this patch.

largefiles: in overridelog, use non-lf matcher for patch generation (issue4334)

This has actually been broken since at least Mercurial 2.8 -- hg log --patch
with largefiles only used to work when no largefiles existed. Rev 5809d62e7106
exposed this bug for all cases.

largefiles: don't override matchandpats for always matchers (issue4334)

This makes hg log --follow --patch work, since in cmdutil._makelogrevset we
use the non-follow matcher for hg log --follow --patch with no file arguments.

test-largefiles: add test for hg log --follow --patch with path

This was the one case for test-largefiles that was not broken.
