c5b423860d Support a fine-grained diff-tree
This is based on a patch by David Woodhouse, but with the selection
tests much simplified and streamlined.

It makes diff-tree take extra arguments, specifying the files or         
directories which should be considered "interesting". Changes in
uninteresting directories are not reported.

e2b6a9d0bf [PATCH] make file merging respect permissions
1) permissions aren't respected in the merge script (primarily because
they're never passed in to it in the first place).  Fix that and also
check for permission conflicts in the merge

2) the delete of a file in both branches may indeed be just that, but it
could also be the indicator of a rename conflict (file moved to
different locations in both branches), so error out and ask the
committer for guidance.

6eb7ed5403 [PATCH] Various transport programs
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.

b6b15db3f4 [PATCH] Replace merge-base implementation
The old implementation was a nice algorithm, but, unfortunately, it could
be confused in some cases and would not necessarily do the obvious thing
if one argument was decended from the other. This version fixes that by
changing the criterion to the most recent common ancestor.

144bde78e9 Use O_NOATIME when opening the sha1 files.
We really don't care about atime, and it sucks to dirty the
inode cache just for it.

This is more than a one-liner only because we need to be able to
clear the O_NOATIME flag in case some of the objects are owned
by others (in which case open will return EPERM), and because not
everybody has the O_NOATIME flag.

b5af910727 New "diff-cache" implementation.
This one is about a million times simpler, and much more likely to be
correct too.

Instead of trying to match up a tree object against the index, we just
read in the tree object side-by-side into the index, and just walk the
resulting index file. This was what all the read-tree cleanups were
all getting to.

This one includes the Mozilla SHA1 implementation sent in by Edgar Toernig.
It's dual-licenced under MPL-1.1 or GPL, so in the context of git, we
obviously use the GPL version. 

Side note: the Mozilla SHA1 implementation is about twice as fast as the
default openssl one on my G5, but the default openssl one has optimized
x86 assembly language on x86. So choose wisely.

65bb49144d Add the ability to prefix something to the pathname to "checkout-cache.c"
This basically makes it trivial to use checkout-cache as a "export as
tree" function. Just read the desired tree into the index, and do a

	checkout-cache --prefix=export-dir/ -a

and checkout-cache will "export" the cache into the specified directory.

NOTE! The final "/" is important. The exported name is literally just
prefixed with the specified string, so you can also do something like

	checkout-cache --prefix=.merged- Makefile

to check out the currently cached copy of "Makefile" into the file
".merged-Makefile".

form of diff-cache nor "-m single-merge" form of read-tree were
described.

b12ec373b8 [PATCH] Teach read-tree about commit objects
Updates read-tree to use read_tree_with_tree_or_commit_sha1()
function.  The command can take either tree or commit IDs with
this patch.

The change involves a slight modification of how it recurses down
the tree.  Earlier the caller only supplied SHA1 and the recurser
read the object using it, but now it is the caller's responsibility
to read the object and give it to the recurser.  This matches the
way recursive behaviour is done in other tree- related commands.

f4913f91a9 [PATCH] Accept commit in some places when tree is needed.
This patch implements read_tree_with_tree_or_commit_sha1(),
which can be used when you are interested in reading an unpacked
raw tree data but you do not know nor care if the SHA1 you
obtained your user is a tree ID or a commit ID.  Before this
function's introduction, you would have called read_sha1_file(),
examined its type, parsed it to call read_sha1_file() again if
it is a commit, and verified that the resulting object is a
tree.  Instead, this function does that for you.  It returns
NULL if the given SHA1 is not either a tree or a commit.

ad4e9ce4f9 [PATCH] make dotest more amenable to commit message editing
This makes "dotest" a lot nicer to sue, especially for people who were
used to editing the commit comments after-the-fact in BK, which git
doesn't apply. 

he syntax is

	dotest [-q] mailbox [signoff]

so the command line operates exactly as you're used to.  If you supply
the -q it will query before applying (I also added the [a]pply all the
rest option).  If the signoff file is absent, no signoff line gets
added. 

There's also one addition in this:  a checkout-cache line.  I added that
for poor saps like me whose laptop takes minutes to checkout a full
build tree, so I can run dotest in a directory with no checked out
files.
