add-interactive: fix bogus diff header line ordering

When we look at a patch for adding hunks interactively, we
first split it into a header and a list of hunks. Some of
the header lines, such as mode changes and deletion, however,
become their own selectable hunks. Later when we reassemble
the patch, we simply concatenate the header and the selected
hunks. This leads to patches like this:

  diff --git a/file b/file
  index d95f3ad..0000000
  --- a/file
  +++ /dev/null
  deleted file mode 100644
  @@ -1 +0,0 @@
  -content

Notice how the deletion comes _after_ the ---/+++ lines,
when it should come before.

In many cases, we can get away with this as git-apply
accepts the slightly bogus input. However, in the specific
case of a deletion line that is being applied via "apply
-R", this malformed patch triggers an assert in git-apply.
This comes up when discarding a deletion via "git checkout
-p".

Rather than try to make git-apply accept our odd input,
let's just reassemble the patch in the correct order.

Implement 'git checkout --patch'

This introduces a --patch mode for git-checkout.  In the index usage

  git checkout --patch -- [files...]

it lets the user discard edits from the <files> at the granularity of
hunks (by selecting hunks from 'git diff' and then reverse applying
them to the worktree).

We also accept a revision argument.  In the case

  git checkout --patch HEAD -- [files...]

we offer hunks from the difference between HEAD and the worktree, and
reverse applies them to both index and worktree, allowing you to
discard staged changes completely.  In the non-HEAD usage

  git checkout --patch <revision> -- [files...]

it offers hunks from the difference between the worktree and
<revision>.  The chosen hunks are then applied to both index and
worktree.

The application to worktree and index is done "atomically" in the
sense that we first check if the patch applies to the index (it should
always apply to the worktree).  If it does not, we give the user a
choice to either abort or apply to the worktree anyway.
