Cloning from a repository with more than 256 refs (heads and tags
included) will choke, because upload-pack has a built-in limit of
feeding not more than MAX_NEEDS (currently 256) heads to underlying
git-rev-list. This is a problem when cloning a repository with many
tags, like http://www.linux-mips.org/pub/scm/linux.git, which has 290+
tags.
This commit introduces a new flag, --all, to git-rev-list, to include
all refs in the repository. Updated upload-pack detects requests that
ask more than MAX_NEEDS refs, and sends everything back instead.
We may probably want to tweak the definitions of MAX_NEEDS and
MAX_HAS, but that is a separate topic.

When we updated the marker for new files from 'N' to 'A', we forgot to
notice that the letter is already taken by the All-Or-None mark.
Change the All-Or-None marker to '*' to resolve this conflict.
git-diff-tree -r --diff-filter='R*' -M

that have renames, in comparison with:
git-diff-tree -r --diff-filter='R' -M
shows the same set of changes but the diff output are limited only to

The fixes focuses on improving the HTML output. Most noteworthy:
- Fix the Makefile to also make various *.html files depend on
included files.
- Consistently use 'NOTE: ...' instead of '[ ... ]' for additional
info.
- Fix ending '::' for description lists in OPTION section etc.
- Fix paragraphs in description lists ending up as preformated text.
- Always use listingblocks (preformatted text wrapped in lines with -----)
for examples that span empty lines, so they are put in only one HTML
block.
- Use '1.' instead of '(1)' for numbered lists.
- Fix linking to other GIT docs.
- git-rev-list.txt: put option descriptions in an OPTION section.

Let the merge strategies handle the base less case if they are able to
do it. It also fixes git-resolve.sh to die if no common ancestors
exists, instead of doing the wrong thing. Furthermore, it contains a
small independent fix for git-merge.sh and a fix for a base less code
path in gitMergeCommon.py.
With this it's possible to use
git merge -s recursive 'merge message' A B
to do a base less merge of A and B.

Using Linus' --trivial option, this handles really trivial case

This makes "git-update-index" avoid the new index file write if it didn't
make any changes to the index.
It still doesn't make things like "git status" be read-only operations in

least avoid making unnecessary changes.

Instead of "git status" ignoring (and hiding) potential errors from the
"git-update-index" call, make it exit if it fails, and show the error.
In order to do this, use the "-q" flag (to ignore not-up-to-date files)
and add a new "--unmerged" flag that allows unmerged entries in the index
without any errors.
This also avoids marking the index "changed" if an entry isn't actually
modified, and makes sure that we exit with an understandable error message
if the index is corrupt or unreadable. "read_cache()" no longer returns an
error for the caller to check.
Finally, make die() and usage() exit with recognizable error codes, if we
ever want to check the failure reason in scripts.

This adds the counterpart of git-update-ref that lets you read
and create "symbolic refs". By default it uses a symbolic link
to represent ".git/HEAD -> refs/heads/master", but it can be compiled
to use the textfile symbolic ref.
The places that did 'readlink .git/HEAD' and 'ln -s refs/heads/blah
.git/HEAD' have been converted to use new git-symbolic-ref command, so
that they can deal with either implementation.

This extends the ref reading to understand a "symbolic ref": a ref file
that starts with "ref: " and points to another ref file, and thus
introduces the notion of ref aliases.
This is in preparation of allowing HEAD to eventually not be a symlink,
but one of these symbolic refs instead.
[jc: Linus originally required the prefix to be "ref: " five bytes
and nothing else, but I changed it to allow and strip any number of
leading whitespaces to match what update-ref.c does.]

A symbolic ref is a regular file whose contents is "ref:", followed by
optional leading whitespaces, followed by a GIT_DIR relative pathname,
followed by optional trailing whitespaces (the optional whitespaces
are unconditionally removed, so you cannot have leading nor trailing
whitespaces). This can be used in place of a traditional symbolic
link .git/HEAD that usually points at "refs/heads/master". You can
instead have a regular file .git/HEAD whose contents is
"ref: refs/heads/master".
[jc: currently the code does not enforce the symbolic ref to begin with
refs/, unlike the symbolic link case. It may be worthwhile to require
either case to begin with refs/ and not have any /./ nor /../ in them.]
