amend: fix copy records handling (issue3410)

Messing with the dirstate before the intermediate commit seems error prone.
Instead, commit and recompute the copies with copies.pathcopies(), then use
that with commitctx().

Since copies.pathcopies() does not support file replacement very well, the
whole .renamed() condition in samefile() is removed and the "file replacement
caused by differing copy source" effect is discarded.

  $ "$TESTDIR/hghave" unix-permissions || exit 80

No local source

  $ hg clone a b
  abort: repository a not found!
  [255]

No remote source

  $ hg clone http://127.0.0.1:3121/a b
  abort: error: Connection refused
  [255]
  $ rm -rf b # work around bug with http clone

Inaccessible source

  $ mkdir a
  $ chmod 000 a
  $ hg clone a b
  abort: repository a not found!
  [255]

Inaccessible destination

  $ hg init b
  $ cd b
  $ hg clone . ../a
  abort: Permission denied: ../a
  [255]
  $ cd ..
  $ chmod 700 a
  $ rm -r a b

Source of wrong type

  $ if "$TESTDIR/hghave" -q fifo; then
  >     mkfifo a
  >     hg clone a b
  >     rm a
  > else
  >     echo "abort: repository a not found!"
  > fi
  abort: repository a not found!

Default destination, same directory

  $ hg init q
  $ hg clone q
  destination directory: q
  abort: destination 'q' is not empty
  [255]

destination directory not empty

  $ mkdir a 
  $ echo stuff > a/a
  $ hg clone q a
  abort: destination 'a' is not empty
  [255]

leave existing directory in place after clone failure

  $ hg init c
  $ cd c
  $ echo c > c
  $ hg commit -A -m test
  adding c
  $ chmod -rx .hg/store/data
  $ cd ..
  $ mkdir d
  $ hg clone c d 2> err
  [255]
  $ test -d d
  $ test -d d/.hg

reenable perm to allow deletion

  $ chmod +rx c/.hg/store/data
