Requests for $GIT_URL/git-receive-pack and $GIT_URL/git-upload-pack
are forwarded to the corresponding backend process by directly
executing it and leaving stdin and stdout connected to the invoking
web server. Prior to starting the backend process the HTTP response
headers are sent, thereby freeing the backend from needing to know
about the HTTP protocol.
Requests that are encoded with Content-Encoding: gzip are
automatically inflated before being streamed into the backend.
This is primarily useful for the git-upload-pack backend, which
receives highly repetitive text data from clients that easily
compresses to 50% of its original size.

When --stateless-rpc is passed as a command line parameter to
upload-pack or receive-pack the programs now assume they may
perform only a single read-write cycle with stdin and stdout.
This fits with the HTTP POST request processing model where a
program may read the request, write a response, and must exit.
When --advertise-refs is passed as a command line parameter only
the initial ref advertisement is output, and the program exits
immediately. This fits with the HTTP GET request model, where
no request content is received but a response must be produced.
HTTP headers and/or environment are not processed here, but
instead are assumed to be handled by the program invoking
either service backend.

The git-http-backend CGI can be configured into any Apache server
using ScriptAlias, such as with the following configuration:
LoadModule cgi_module /usr/libexec/apache2/mod_cgi.so
LoadModule alias_module /usr/libexec/apache2/mod_alias.so
ScriptAlias /git/ /usr/libexec/git-core/git-http-backend/
Repositories are accessed via the translated PATH_INFO.
The CGI is backwards compatible with the dumb client, allowing all
older HTTP clients to continue to download repositories which are
managed by the CGI.

When we use -c, -C, or --amend, we are trying one of two things: using the
source as a template or modifying a commit with corrections.
When these options are used, the authorship and timestamp recorded in the
newly created commit are always taken from the original commit. This is
inconvenient when we just want to borrow the commit log message or when
our change to the code is so significant that we should take over the
authorship (with the blame for bugs we introduce, of course).
The new --reset-author option is meant to solve this need by regenerating
the timestamp and setting the committer as the new author.

cmd_ls_remote() was calling transport_get() with a NULL remote and a
non-NULL url in the case where it was run outside a git
repository. This involved a bunch of ill-tested special
cases. Instead, simply get the struct remote for the URL with
remote_get(), which works fine outside a git repository, and can also
take global options into account.
This fixes a tiny and obscure bug where "git ls-remote" without a repo
didn't support global url.*.insteadOf, even though "git clone" and
"git ls-remote" in any repo did.
Also, enforce that all callers provide a struct remote to transport_get().

When displaying diffs in a submodule, this makes gitk display the
headlines of the commits being diffed, instead of just showing
not-quite-helpful SHA-1 pairs, if the underlying git installation
supports this. That makes it much easier to evaluate the changes, as
it eliminates the need to start a gitk inside the submodule and use
the superprojects hashes there to find out what the commits are about.
Since the --submodule option of git diff is new in git version 1.6.6,
this only uses the --submodule option when a git version of 1.6.6 or
higher is detected.

When we introduced the "word diff" mode, we could have done one of three
things:
* change fn_out_consume() to "this is called every time a line worth of
diff becomes ready from the lower-level diff routine. This function
knows two sets of helpers (one for line-oriented diff, another for word
diff), and each set has various functions to be called at certain
places (e.g. hunk header, context, ...). The function's role is to
inspect the incoming line, and dispatch appropriate helpers to produce
either line- or word- oriented diff output."
* introduce fn_out_consume_word_diff() that is "this is called every time
a line worth of diff becomes ready from the lower-level diff routine,
and here is what we do to prepare word oriented diff using that line."
without touching fn_out_consume() at all.
* Do neither of the above, and keep fn_out_consume() to "this is called
every time a line worth of diff becomes ready from the lower-level diff
routine, and here is what we do to output line oriented diff using that
line." but sprinkle a handful of 'are we in word-diff mode? if so do
this totally different thing' at random places.
This patch is to at least abstract the details of "this totally different
thing" out from the main codepath, in order to improve readability.
We can later refactor it by introducing fn_out_consume_word_diff(), taking
the second route above, but that is a separate topic.

The remote helper interface now supports the push capability,
which can be used to ask the implementation to push one or more
specs to the remote repository. For remote-curl we implement this
by calling the existing WebDAV based git-http-push executable.
Internally the helper interface uses the push_refs transport hook
so that the complexity of the refspec parsing and matching can be
reused between remote implementations. When possible however the
helper protocol uses source ref name rather than the source SHA-1,
thereby allowing the helper to access this name if it is useful.
>From Clemens Buchacher <drizzd@aon.at>:
update http tests according to remote-curl capabilities
o Pushing packed refs is now fixed.
o The transport helper fails if refs are already up-to-date. Add
a test for that.
o The transport helper will notice if refs are already
up-to-date. We therefore need to update server info in the
unpacked-refs test.
o The transport helper will purge deleted branches automatically.
o Use a variable ($ORIG_HEAD) instead of full SHA-1 name.

Some network protocols (e.g. native git://) are able to fetch more
than one ref at a time and reduce the overall transfer cost by
combining the requests into a single exchange. Instead of feeding

at once so the helper can decide whether or not it should batch them.

When multi_ack_detailed is enabled the ACK continue messages returned
by the remote upload-pack are broken out to describe the different
states within the peer. This permits the client to better understand
the server's in-memory state.
The fetch-pack/upload-pack protocol now looks like:
NAK
---------------------------------
Always sent in response to "done" if there was no common base
selected from the "have" lines (or no have lines were sent).
* no multi_ack or multi_ack_detailed:
Sent when the client has sent a pkt-line flush ("0000") and
the server has not yet found a common base object.
* either multi_ack or multi_ack_detailed:
Always sent in response to a pkt-line flush.
ACK %s
-----------------------------------
* no multi_ack or multi_ack_detailed:
Sent in response to "have" when the object exists on the remote
side and is therefore an object in common between the peers.
The argument is the SHA-1 of the common object.
* either multi_ack or multi_ack_detailed:
Sent in response to "done" if there are common objects.
The argument is the last SHA-1 determined to be common.
ACK %s continue
-----------------------------------
* multi_ack only:
Sent in response to "have".
The remote side wants the client to consider this object as
common, and immediately stop transmitting additional "have"
lines for objects that are reachable from it. The reason
the client should stop is not given, but is one of the two
cases below available under multi_ack_detailed.
ACK %s common
-----------------------------------
* multi_ack_detailed only:
Sent in response to "have". Both sides have this object.
Like with "ACK %s continue" above the client should stop
sending have lines reachable for objects from the argument.
ACK %s ready
-----------------------------------
* multi_ack_detailed only:
Sent in response to "have".
The client should stop transmitting objects which are reachable
from the argument, and send "done" soon to get the objects.
If the remote side has the specified object, it should
first send an "ACK %s common" message prior to sending
"ACK %s ready".
Clients may still submit additional "have" lines if there are
more side branches for the client to explore that might be added
to the common set and reduce the number of objects to transfer.

By changing the enabled capabilities to be formatted in a strbuf
it is easier to add a new capability to the set of supported

strategy results in up-to-date or fast-forward, the
