import: add --partial flag to create a changeset despite failed hunks

The `hg import` command gains a `--partial` flag. When specified, a commit will
always be created from a patch import. Any hunk that fails to apply will
create .rej file, same as what `hg qimport` would do. This change is mainly
aimed at preserving changeset metadata when applying a patch, something very
important for reviewers.

In case of failure with `--partial`, `hg import` returns 1 and the following
message is displayed:

    patch applied partially
    (fix the .rej files and run `hg commit --amend`)

When multiple patches are imported, we stop at the first one with failed hunks.

In the future, someone may feel brave enough to tackle a --continue flag to
import.

  $ hg init

  $ hg add sub/b
  $ hg commit -m "second" sub/b

  $ cat sub/b
  321

  $ hg co 0
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved

  $ cat sub/b 2>/dev/null || echo "sub/b not present"
  sub/b not present

  $ test -d sub || echo "sub not present"
