Johannes Schindelin 2235a37cb7 built-in add -p: prepare for patch modes other than "stage" ...

The Perl script backing `git add -p` is used not only for that command,
but also for `git stash -p`, `git reset -p` and `git checkout -p`.

In preparation for teaching the C version of `git add -p` to support
also the latter commands, let's abstract away what is "stage" specific
into a dedicated data structure describing the differences between the
patch modes.

As we prepare for calling the built-in `git add -p` in
`run_add_interactive()` via code paths that have not let `add_config()`
do its work, we have to make sure to re-parse the config using that
function in those cases.

Finally, please note that the Perl version tries to make sure that the
diffs are only generated for the modified files. This is not actually
necessary, as the calls to Git's diff machinery already perform that
work, and perform it well. This makes it unnecessary to port the
`FILTER` field of the `%patch_modes` struct, as well as the
`get_diff_reference()` function.
