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.
