Without -f flag, 'git-checkout-index foo.c' issued an error message
when foo.c already existed in the working tree and did not match index.
However it did not return an error from the underlying checkout_entry()
function and resulted in a successful exit(0).

As promised, this is the "big tool rename" patch. The primary differences
since 0.99.6 are:
(1) git-*-script are no more. The commands installed do not
have any such suffix so users do not have to remember if
something is implemented as a shell script or not.
(2) Many command names with 'cache' in them are renamed with
'index' if that is what they mean.
There are backward compatibility symblic links so that you and
Porcelains can keep using the old names, but the backward
compatibility support is expected to be removed in the near
future.

The symlink case had never worked, and the file case was broken by the
O_EXCL change because the error return changed from EISDIR to EEXIST.
Fix both problems by just moving the test for an existing directory to a
more logical place.
We should always have unlinked any old ones before, but this just makes
sure that we never over-write any old file.
A quick "grep" now shows that all the core tools that open files for
writing use O_EXCL, ie we never overwrite an existing file in place.
IIRC our strategy was to let the users' umask take care of the
final mode bits. This patch fixes places that deviate from it.
