bug#62693: 28.2; VC: CVS: Fix lost file reporting and enable reverting it

[Olivier Certner]

Hi,

When using CVS 1.12.3+, VC dir doesn't list correctly some missing file, 
including quotes produced by CVS in the file name, then preventing to operate 
on it. The fix works on all "recent" versions of CVS (1.11 and 1.12).

Once this is fixed, it's still not possible to revert such a file yet since 
`vc-default-revert', called by `vc-cvs-revert', tries to backup the 
non-existing file (`copy-file' just fails).

While here, fixed `vc-cvs-parse-root', which is not correctly reporting whether 
some repository is local.

All three patches can be applied to 'master' directly (e579c9cc33d).

Regards.
