This processes objects in two simultaneous passes. Each object will
first be given to prefetch(), as soon as it is possible to tell that
it will be needed, and then will be given to fetch(), when it is the
next object that needs to be parsed. Unless an implementation does
something with prefetch(), this should have no effect.

This adds support to http-pull for finding the list of pack files
available on the server, downloading the index files for those pack
files, and downloading pack files when they contain needed objects not
available individually. It retains the index files even if the pack
files were not needed, but downloads the list of pack files once per
run if an object is not found separately.

Old libcurl has curl_easy_setopt(), and http-pull requires it; it just
doesn't have one of the options.

Some newer features of libcurl are used which are not strictly necessary
for http-pull. Use them only if libcurl is new enough to know about them.
[jc: I just reworked #ifdef sprinkled all over the code into a
single section that defines a set of macros.]

Cause setting environment variable GIT_SSL_NO_VERIFY to turn off
curl's ssl peer verification.
Only use curl for http transfers, instead of curl and wget.
Make curl check ~/.netrc for credentials.

Packed delta files created by git-pack-objects seems to be the
way to go, and existing "delta" object handling code has exposed
the object representation details to too many places. Remove it
while we refactor code to come up with a proper interface in
sha1_file.c.

This adds support to pull.c for requesting a reference and writing it to a
file. All of the git-*-pull programs get stubs for now.

This addresses a concern raised by Jason McMullan in the mailing
list discussion. After retrieving and storing a potentially
deltified object, pull logic tries to check and fulfil its delta
dependency. When the pull procedure is killed at this point,
however, there was no easy way to recover by re-running pull,
since next run would have found that we already have that
deltified object and happily reported success, without really
checking its delta dependency is satisfied.
This patch introduces --recover option to git-*-pull family
which causes them to re-validate dependency of deltified objects
we are fetching. A new test t5100-delta-pull.sh covers such a
failure mode.

When a remote repository is deltified, we need to get the
objects that a deltified object we want to obtain is based upon.
The initial parts of each retrieved SHA1 file is inflated and
inspected to see if it is deltified, and its base object is
asked from the remote side when it is. Since this partial
inflation and inspection has a small performance hit, it can
optionally be skipped by giving -d flag to git-*-pull commands.
This flag should be used only when the remote repository is
known to have no deltified objects.
Rsync transport does not have this problem since it fetches
everything the remote side has.

Add <limits.h> to the include files handled by "cache.h", and remove
extraneous #include directives from various .c files. The rule is that
"cache.h" gets all the basic stuff, so that we'll have as few system
dependencies as possible.

- Raw hashes should be unsigned char.
- String functions want signed char.
- Hash and compress functions want unsigned char.

This moves the private "say()" function to pull.c, renames it to
"pull_say()", and introduces a global variable "get_verbosely" that
makes the pull backends report what they fetch. The -v option is
added to git-rpull and git-http-pull to match git-local-pull.
The documentation is updated to describe these pull commands.

Currently pull() calls fetch() without checking whether we have
the wanted object but all of the existing fetch()
implementations perform this check and return success
themselves. This patch moves the check to the caller.
I will be sending a trivial git-local-pull which depends on
this in the next message.

The method for deciding what to pull is useful separately from any of the
ways of actually fetching the objects.

This patch adds three similar and related programs. http-pull downloads
objects from an HTTP server; rpull downloads objects by using ssh and
rpush on the other side; and rpush uploads objects by using ssh and rpull
on the other side.
The algorithm should be sufficient to make the network throughput required
depend only on how much content is new, not at all on how much content the
repository contains.
The combination should enable people to have remote repositories by way of
ssh login for authenticated users and HTTP for anonymous access.
