If by chance we receive a pack which content (list of objects) matches
another pack that we already have, and if that pack is marked with a
.keep file, then we should not overwrite it.

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.

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.

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.

Minor grammar fixes for git-diff-index.txt
link_temp_to_file: call adjust_shared_perm() only when we created the directory
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:
summary 3134 +/- 24.2 ms --> 1081 +/- 30.2 ms
tags 2886 +/- 18.9 ms --> 1196 +/- 15.6 ms

This adds "creator" (which is parallel to "tagger" or "committer")
and "creatordate" (corresponds to "taggerdate" and
"committerdate").
As other "date" fields, "creatordate" sorts numerically
and displays human readably. This allows for example for
sorting together heavyweigth and lightweight tags.

push-all = push -v --repo=all

add to the project-local config file
[remote "all"]
