Remove unsupported C99 style struct initializers in git-archive.
At least one older version of the Solaris C compiler doesn't support
the newer C99 style struct initializers. To allow Git to compile
on those systems use an archive description struct which is easier
to initialize without the C99 struct initializer syntax.
Also since the archives array is not used by anyone other than
archive.c we can make it static.

Remove SIMPLE_PROGRAMS and make git-daemon a normal program.
Some platforms (Solaris in particular) appear to require -lz as
part of the link line for git-daemon, due to it linking against
sha1_file.o and that module requiring inflate/deflate support.
So its time to retire SIMPLE_PROGRAMS and move its last remaining
member into the standard PROGRAMS list, allowing it to link against
all libraries used by the rest of Git.

git-pickaxe: re-scan the blob after making progress with -C
The reason to do this is the same as in the previous change for
line copy detection within the same file (-M).
Also this fixes -C and -C -C (aka find-copies-harder) logic; in
this application we are not interested in the similarity
matching diffcore-rename makes, because we are only interested
in scanning files that were modified, or in the case of -C -C,
scanning all files in the parent and we want to do that
ourselves.
git-pickaxe: re-scan the blob after making progress with -M
Otherwise we would miss copied lines that are contained in the
parts before or after the part that we find after splitting the
blame_entry (i.e. split[0] and split[2]).
We deduced a GNU diff output that does not use /dev/null convention
as creation (deletion) diff correctly by looking at the lack of context
and deleted lines (added lines), but forgot to reset the new (old) name
field properly.
This was a regression when we added a workaround for --unified=0 insanity.

remove .keep pack lock files when done with refs update
This makes both git-fetch and git-push (fetch-pack and receive-pack)

file after refs have been updated.

Since functions in fetch-clone.c were only used from fetch-pack.c,
its content has been merged with fetch-pack.c. This allows for better
coupling of features with much simpler implementations.
One new thing is that the (abscence of) --thin also enforce it on
index-pack now, such that index-pack will abort if a thin pack was
_not_ asked for.
The -k or --keep, when provided twice, now causes the fetched pack
to be left as a kept pack just like receive-pack currently does.
Eventually this will be used to close a race against concurrent
repacking.

Teach receive-pack how to keep pack files based on object count.
Since keeping a pushed pack or exploding it into loose objects
should be a local repository decision this teaches receive-pack
to decide if it should call unpack-objects or index-pack --stdin
--fix-thin based on the setting of receive.unpackLimit and the
number of objects contained in the received pack.
If the number of objects (hdr_entries) in the received pack is
below the value of receive.unpackLimit (which is 5000 by default)
then we unpack-objects as we have in the past.
If the hdr_entries >= receive.unpackLimit then we call index-pack and
ask it to include our pid and hostname in the .keep file to make it
easier to identify why a given pack has been kept in the repository.
Currently this leaves every received pack as a kept pack. We really
don't want that as received packs will tend to be small. Instead we
want to delete the .keep file automatically after all refs have
been updated. That is being left as room for future improvement.

Allow pack header preprocessing before unpack-objects/index-pack.
Some applications which invoke unpack-objects or index-pack --stdin
may want to examine the pack header to determine the number of
objects contained in the pack and use that value to determine which
executable to invoke to handle the rest of the pack stream.
However if the caller consumes the pack header from the input stream
then its no longer available for unpack-objects or index-pack --stdin,
both of which need the version and object count to process the stream.
This change introduces --pack_header=ver,cnt as a command line option
that the caller can supply to indicate it has already consumed the
pack header and what version and object count were found in that
header. As this option is only meant for low level applications
such as receive-pack we are not documenting it at this time.

gitweb: Use git-for-each-ref to generate list of heads and/or tags
Add two subroutines: git_get_heads_list and git_get_refs_list, which
fill out needed parts of refs info (heads and tags respectively) info
using single call to git-for-each-ref, instead of using
git-peek-remote to get list of references and using parse_ref for each
ref to get ref info, which in turn uses at least one call of git
command.
Replace call to git_get_refs_list in git_summary by call to
git_get_references, git_get_heads_list and git_get_tags_list
(simplifying this subroutine a bit). Use git_get_heads_list in
git_heads and git_get_tags_list in git_tags. Modify git_tags_body
slightly to accept output from git_get_tags_list.
Remove no longer used, and a bit hackish, git_get_refs_list.
parse_ref is no longer used, but is left for now.
Generating "summary" and "tags" views should be much faster for
projects which have large number of tags.
CHANGES IN OUTPUT: Before, if ref in refs/tags was tag pointing to
commit we used committer epoch as epoch for ref, and used tagger epoch
as epoch only for tag pointing to object of other type. If ref in
refs/tags was commit, we used committer epoch as epoch for ref (see
parse_ref; we sorted in gitweb by 'epoch' field).
Currently we use committer epoch for refs pointing to commit objects,
and tagger epoch for refs pointing to tag object, even if tag points
to commit.
Simple ab benchmark before and after this patch for my git.git
repository (git/jnareb-git.git) with some heads and tags added
as compared to git.git repository, shows around 2.4-3.0 times speedup
for "summary" and "tags" views:

This is a shorthand for "<rev> --not <rev>^@", i.e. "include
this commit but exclude any of its parents".
When a new file $F is introduced by revision $R, this notation
can be used to find a copy-and-paste from existing file in the
parents of that revision without annotating the ancestry of the
lines that were copied from:
git-pickaxe: cache one already found path per commit.
Depending on how bushy the commit DAG is, this saves calls to
the internal diff-tree for fork-point commits. For example,
annotating Makefile in the kernel repository saves about a third
of such diff-tree calls.

git-pickaxe: split find_origin() into find_rename() and find_origin().
When a merge adds a new file from the second parent, the
earlier code tried to find renames in the first parent before
noticing that the vertion from the second parent was added
without modification.
quote.c: ensure the same quoting across platforms.
We read a byte from "char *" and compared it with ' ' to decide
if it needs quoting to protect textual output. With a platform
where char is unsigned char that would give different result.
The origin structure is allocated for each commit and path while
the code traverse down it is copied into different blame entries.
To avoid leaks, try refcounting them.
This still seems to leak, which I haven't tracked down fully yet.
To prevent a race condition between `index-pack --stdin` and
`repack -a -d` where the repack deletes the newly created pack
file before any refs are updated to reference objects contained
within it we mark the pack file as one that should be kept. This
removes it from the list of packs that `repack -a -d` will consider
for removal.
Callers such as `receive-pack` which want to invoke `index-pack`
should use this new --keep option to prevent the newly created pack
and index file pair from being deleted before they have finished any
related ref updates. Only after all ref updates have been finished
should the associated .keep file be removed.

Only repack active packs by skipping over kept packs.
During `git repack -a -d` only repack objects which are loose or
which reside in an active (a non-kept) pack. This allows the user
to keep large packs as-is without continuous repacking and can be
very helpful on large repositories. It should also help us resolve
a race condition between `git repack -a -d` and the new pack store
functionality in `git-receive-pack`.
Kept packs are those which have a corresponding .keep file in
$GIT_OBJECT_DIRECTORY/pack. That is pack-X.pack will be kept
(not repacked and not deleted) if pack-X.keep exists in the same
directory when `git repack -a -d` starts.
Currently this feature is not documented and there is no user

send-pack --keep: do not explode into loose objects on the receiving end.
This adds "keep-pack" extension to send-pack vs receive pack protocol,
and makes the receiver invoke "index-pack --stdin --fix-thin".
With this, you can ask send-pack not to explode the result into
loose objects on the receiving end.
I've patched has_sha1_file() to re-check for added packs just
like is done in read_sha1_file() for now, but I think the static
"re-prepare" interface for packs was a mistake. Creation of a
new pack inside a process that needs to read objects in them
back ought to be a rare event, so we are better off making the
callers (such as receive-pack that calls "index-pack --stdin
--fix-thin") explicitly call re-prepare. That way we do not
have to penalize ordinary users of read_sha1_file() and
has_sha1_file().

merge-recursive: adjust to loosened "working file clobbered" check

presense of the file in the working tree that is involved in a

merge: loosen overcautious "working file will be lost" check.
The three-way merge complained unconditionally when a path that

existed in the working tree. If we are merging an old version
that had that path tracked, but the path is not tracked anymore,
and if we are merging that old version in, the result will be
that the path is not tracked. In that case we should not
complain.

Now that index-pack can be streamed with a pack, it is probably a good
idea to use it directly instead of creating a temporary file and running
index-pack afterwards. This way index-pack can abort early whenever a
corruption is encountered even if the pack has not been fully
downloaded, it can display a progress percentage as it knows how much to
expects, and it is a bit faster since the pack indexing is partially
done as data is received. Using fetch -k doesn't need to disable thin
pack generation on the remote end either.
