As a general principle, we should not use "git diff" to validate the
results of what git command that is being tested has done. We would not
know if we are testing the command in question, or locating a bug in the
cute hack of "git diff --no-index".
Rather use test_cmp for that purpose.

Instead of forking update-index, call refresh_cache() directly.

Since reset is a builtin now, it can use the full power of libgit.a
and check for unmerged entries itself.

The purpose of the function update_index_from_diff() (which is the
callback function we give do_diff_cache()) is to update those index
entries which differ from the given commit.
Since do_diff_cache() plays games with the in-memory index, this function
discarded the cache and reread it.
Then, back in the function read_from_tree() we wrote the index.
Of course, this broke down when there were no changes and
update_index_from_diff() was not called, and therefore the mangled index
was not discarded.
The solution is to move the index writing into the function
update_index_from_diff().

This adds the new file t/t7102-reset.sh following the text
and examples in "Documentation/git-reset.txt" in order to
check the behaviour of the upcoming "builtin-reset.c",
and be able to compare it with the original "git-reset.sh".
