Otherwise, git-clone silently failed to clone a remote
repository where redirections (ie. a response with a
"Location" header line) are used.
This includes the fixes from Nick Hengeveld.

After using cg-update to pull, empty files named *.temp are left in
the various subdirectories of .git/objects/. These are created by
git-http-fetch to hold data as it's being fetched from the remote
repository. They are left behind after a transfer error so that the
next time git-http-fetch runs it can pick up where it left off. If
they're empty though, it would make more sense to delete them rather
than leaving them behind for the next attempt.

git-http-fetch spits out curl 404 error message when unable to fetch an object,
but that's confusing since no error really happened and the object is usually
found in a pack it tries right after that. And if the object still cannot be
retrieved, it will say another error message anyway. OTOH other HTTP errors
(403 etc) are likely fatal and the user should be still informed about them.

This patch cleans out all sparse warnings from http-fetch.c
I'm a bit uncomfortable with adding extra #ifdefs to avoid either
'mixing declaration with code' or 'unused variable' warnings, but I
figured that since those functions are already littered with #ifdefs I
might just get away with it. Comments?
[jc: I adjusted Peter's patch to address uncomfortableness issues.]

No need to hate it. Here comes the rebased patch, and this time, I

git-http-fetch received objects/info/packs into a fixed-size buffer
and started to fail when this file became larger than the buffer.
Change it to grow the buffer dynamically, and do the same thing for
objects/info/alternates. Also add missing free() calls for these
buffers.

curl_escape ought to do this, but we should not let it quote
slashes (nobody said refs/tags cannot have subdirectories), so
we roll our own safer version. With this, the last part of
git-clone from Martin's moodle repository that used to fail now
works, which reads:
$ git-http-fetch -v -a -w 'tags/MOODLE_15_MERGED **INVALID**' \
'tags/MOODLE_15_MERGED **INVALID**' \

The http commit walker cannot use the same temporary file
creation code because it needs to use predictable temporary
filename for partial fetch continuation purposes, but the code
to move the temporary file to the final location should be
usable from the ordinary object creation codepath.
Export move_temp_to_file from sha1_file.c and use it, while
losing the custom relink_or_rename function from http-fetch.c.
Also the temporary object file creation part needs to make sure
the leading path exists, in preparation of the really lazy
fan-out directory creation.

The parallel request changes didn't properly implement the previous patch to
allow caching of retrieved objects by proxy servers. Restore the previous
functionality such that by default requests include the "Pragma: no-cache"
header, and this header is removed on requests for pack indexes, packs, and
objects.

Be sure not to fetch objects that already exist in the local repository.
The main process loop no longer performs this check, http-fetch now checks
prior to starting a new request queue entry and when fetch_object() is called,
and local-fetch now checks when fetch_object() is called.
As discussed in this thread: http://marc.theaimsgroup.com/?t=112854890500001

Add support for parallel HTTP transfers. Prefetch populates a queue of
objects to transfer and starts feeding requests to an active request
queue for processing; fetch_object keeps the active queue moving
while the specified object is being transferred. The size of the active
queue can be restricted using -r and defaults to 5 concurrent transfers.
Requests for objects that are not prefetched are also processed via the
active queue.

Add the sanity checks discussed on the list with Nick Hengeveld in
<20050927000931.GA15615@reactrix.com>.
* unlink of previous and rename from temp to previous can fail for
reasons other than benign ones (missing previous and missing temp).
Report these failures when we encounter them, to make diagnosing
problems easier.
* when rewinding the partially written result, make sure to
truncate the file.
Also verify the pack after downloading by calling
verify_packfile().

This allows the remote repository to refer to additional repositories
in a file objects/info/http-alternates or
objects/info/alternates. Each line may be:
a relative path, starting with ../, to get from the objects directory
of the starting repository to the objects directory of the added
repository.
an absolute path of the objects directory of the added repository (on
the same server).
(only in http-alternates) a full URL of the objects directory of the
added repository.

By default the curl library adds "Pragma: no-cache" header to all
requests, which disables caching by proxy servers. However, most
files in a GIT repository are immutable, and caching them is safe and
could be useful.
This patch removes the "Pragma: no-cache" header from requests for all
files except the pack list (objects/info/packs) and references
(refs/*), which are really mutable and should not be cached.

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.
