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
shows all the changes (not just renames) that are contained in commits
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
renaming changes.

Without -f flag, 'git-checkout-index foo.c' issued an error message

However it did not return an error from the underlying checkout_entry()

H. Peter Anvin says that Samba "promotes" symlinks to hardlinks while
Cygwin itself uses .lnk files to emulate symlinks. Avoid using symbolic
link for .git/HEAD on Cygwin.
This does not help the symlinks recorded in trees as user data, but
at least we do not use them for our own bookkeeping.

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.

Unlike cases where "no such object exists", the case where specified

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
inside git-merge itself, without using any strategy modules.
A 'really trivial case' is:
- we are merging one branch into the current branch;
- there is only one merge base between the branches;
- there is no file-level merge required.

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
general, but if the index file doesn't need refreshing, it now will at
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.
