Instead of checking if explicit SHA-1 in commit log message is sha1 of
commit and making link to "commit" view, make [fragment of] explicit
SHA-1 in commit log message link to "object" view.  While at it allow
to hyperlink also shortened SHA-1, from 8 characters up to full SHA-1,
instead of requiring full 40 characters of SHA-1.

This makes the following changes:

 * SHA-1 of objects which no longer exists, for example in commit
   cherry-picked from no longer existing temporary branch, or revert
   of commit in rebased branch, are no longer marked as such by not
   being made into hyperlink (and not having default hyperlink view:
   being underlined among others).  On the other hand it makes gitweb
   to not write error messages when object is not found to web serwer
   log; it also moves cost of getting type and SHA-1 validation to
   when link is clicked, and not only viewed.

 * SHA-1 of other objects: blobs, trees, tags are also hyperlinked
   and lead to appropriate view (although in the case of tags it is
   more natural to just use tag name).

 * You can put shortened SHA-1 of commit in the commit message, and it
   would be hyperlinked; it would be checked on clicking if abbrev is
   unique.

Make symbolic link target in "tree" view into hyperlink to generic
"object" view (as we don't know if the link target is file (blob) or
directory (tree), and if it exist at all).

Target of link is made into hyperlink when:
 * hash_base is provided (otherwise we cannot find hash
   of link target)
 * link is relative
 * in no place link goes out of root tree (top dir)

Full path of symlink target from the root dir is provided in the title
attribute of hyperlink.

Currently symbolic link name uses ordinary file style (hidden
hyperlink), while the hyperlink to symlink target uses default
hyperlink style, so it is underlined while link target which is not
made into hyperlink is not underlined.

Add generic "object" view implemented in git_object subroutine, which is
used to display object of any type; to be more exact it redirects to the
view of correct type: "blob", "tree", "commit" or "tag".  To identify object
you have to provide either hash (identifier of an object), or (in the case of
tree and blob objects) hash of commit object (hash_base) and path (file_name).

  Make sure the empty tree exists when needed in merge-recursive.
  Don't use memcpy when source and dest. buffers may overlap
  no need to install manpages as executable

There are some baseless merge cases where git-merge-recursive will
try to compare one of the branches against the empty tree.  However
most projects won't have the empty tree object in their object database
as Git does not normally create empty tree objects.  If the empty tree
object is missing then the merge process will die, as it cannot load the
object from the database.  The error message may make the user think that
their database is corrupt when its actually not.

So instead we should just create the empty tree object whenever it is
needed.  If the object already exists as a loose object then no harm
done.  Otherwise that loose object will be pruned away later by either
git-prune or git-prune-packed.

Thanks goes to Junio for suggesting this fix.

Currently the treshold is 5000.  The likelihood of this value to ever be
crossed for a single push is really small making it not really useful.

The optimal treshold for a pure space saving on a filesystem with 4kb
blocks is 3.  However this is likely to create many small packs
concentrating a large number of files in a single directory compared to
the same objects which are spread over 256 directories when loose.  This
means we would need 512 objects per pack on average to approximagte the
same directory cost (a pack has 2 files because of the index).

But 512 is a really high value just like 5000 since most pushes are
unlikely to have that many objects.  So let's try with a value of 100
which should have a good balance between small pushes going to be
exploded into loose objects and large pushes kept as whole packs.

This is not a replacement for periodic repacks of course.

Modify cvs-migration.txt so it explains first how to develop against a
shared repository, then how to set up a shared repository, then how to
import a repository from cvs.  Though this seems chronologically
backwards, it's still readable in this order, and it puts the more
commonly needed material closer to the front.

Remove the annotate/pickaxe section; perhaps it can find a place elsewhere
in the future.  Remove most of the "why git is better than cvs" stuff from
the introduction.

Add some minor clarifications, including two that have come up several
times on the mailing list:

	1. Recommend committing any changes before running pull.
	2. Note that changes must be commited before they can be pushed.

  git-reset to remove "$GIT_DIR/MERGE_MSG"
  unpack-trees: make sure "df_conflict_entry.name" is NUL terminated.

An earlier commit a9cb3c6e changed git-commit to use the
contents of MERGE_MSG even when we do not have MERGE_HEAD (the
rationale is in its log message).

However, the change tricks the following sequence to include a
merge message in a completely unrelated commit:

	$ git pull somewhere
	: oops, the conflicts are too much.  forget it.
        $ git reset --hard
        : work work work
        $ git commit

To fix this confusion, this patch makes "git reset" to remove
the leftover MERGE_MSG that was prepared when the user abandoned
the merge.
