Fix object re-hashing

The hashed object lookup had a subtle bug in re-hashing: it did

for (i = 0; i < count; i++)
if (objs[i]) {
.. rehash ..

where "count" was the old hash couny. Oon the face of it is obvious, since
it clearly re-hashes all the old objects.

However, it's wrong.

If the last old hash entry before re-hashing was in use (or became in use
by the re-hashing), then when re-hashing could have inserted an object
into the hash entries with idx >= count due to overflow. When we then
rehash the last old entry, that old entry might become empty, which means
that the overflow entries should be re-hashed again.

In other words, the loop has to be fixed to either traverse the whole
array, rather than just the old count.

(There's room for a slight optimization: instead of counting all the way
up, we can break when we see the first empty slot that is above the old
"count". At that point we know we don't have any collissions that we might
have to fix up any more. This patch only does the trivial fix)

Make "git clone" less of a deathly quiet experience

now that we don't unpack the initial clone pack any more, it doesn't. And
I'd love to do that nice percentage view in the pack objects downloader
too, but the thing doesn't even read the pack header, much less know how
much it's going to get, so I was lazy and didn't.

Instead, it at least prints out how much data it's gotten, and what the
packing speed is. Which makes the user realize that it's actually doing
something useful instead of sitting there silently (and if the recipient
knows how large the final result is, he can at least make a guess about
when it migt be done).

So with this patch, I get something like this on my DSL line:

where even the speed approximation seems to be roughtly correct (even
though my algorithm is a truly stupid one, and only really gives "speed in
the last half second or so").

Anyway, _something_ like this is definitely needed. It could certainly be
better (if it showed the same kind of thing that git-unpack-objects did,
that would be much nicer, but would require parsing the object stream as
it comes in). But this is  big step forward, I think.

I would also like to make "--cc" the default if you do patches, but didn't
actually do that.

The raw output format is not wonderfully pretty, but it's distinguishable

one colon at the beginning, while a multi-parent raw diff has <n> colons
for <n> parents.

So now, in the kernel, when you do

(to see the manual ARM merge that had a conflict in arch/arm/Kconfig), you

ie you see two colons (two parents), then three modes (parent modes
followed by result mode), then three sha1s (parent sha1s followed by
result sha1).

Which is pretty close to the normal raw diff output.

Cool/stupid exercise:

$ git-whatchanged | grep '^::' | cut -f2- | sort |
  uniq -c | sort -n | less -S

 - "git commit --include paths..." (or "git commit -i paths...")

   have complained that it is confusing to them.  It

   1. refuses to run if $GIT_DIR/MERGE_HEAD exists, and reminds
      trained git users that the traditional semantics now needs
      -i flag.

   2. refuses to run if named paths... are different in HEAD and
      the index (ditto about reminding).  Added paths are OK.

   3. reads HEAD commit into a temporary index file.

   4. updates named paths... from the working tree in this
      temporary index.

   5. does the same updates of the paths... from the working
      tree to the real index.

   6. makes a commit using the temporary index that has the
      current HEAD as the parent, and updates the HEAD with this
      new commit.

 - "git commit --all" can run from a subdirectory, but it updates
   the index with all the modified files and does a whole tree
   commit.

 - In all cases, when the command decides not to create a new
   commit, the index is left as it was before the command is
