sidedatacopies: directly fetch copies information from sidedata
When using the sidedata mode, we don't need a complicated and expensive
`context` object. Instead we directly fetch copies information from the
sidedata (through a changelogrevision object). More optimisations coming.

Test in repo using eol extension, while keeping an eye on how filters are
applied:
$ cd repo
$ hg up -q -c -r null
$ cat > .hg/hgrc <<EOF
> [extensions]
> eol =
> EOF
Update to revision 0 which has no .hgeol, shouldn't use any filters, and
obviously should leave things as tidy as they were before the clean update.

Abort the merge with up -C to revision 0.
Note that files are filtered correctly for revision 0: f is not filtered, a.txt
is filtered with tolf, and everything is left tidy.
