The function fetch_alternates() is called only once from the
main now.

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

Use an environment variable rather than a command-line argument to set the
parallel HTTP request limit. This allows the setting to work whether
git-http-fetch is run directly or via git-fetch.

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.

Don't unlink the temp file when an object transfer fails, so next attempt

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().

Unlike write_sha1_file() that tries to create the object file in a
temporary location and then move it to the final location, fetch_object
could have been interrupted in the middle, leaving a corrupt file.

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.

This tries .../objects/info/http-alternates and then
.../objects/info/alternates, looking for a file which specifies where
else to download objects and packs from.
It currently only supports absolute paths, and doesn't support full URLs.

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.

SHA1_FILE_DIRECTORIES AUTHOR_DATE AUTHOR_EMAIL AUTHOR_NAME
COMMIT_AUTHOR_EMAIL COMMIT_AUTHOR_NAME SHA1_FILE_DIRECTORY

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.
