A patch from David Rientjes made me realize we do not have to have
this function -- just call diff_unmodified_pair() directly.

I've always found difficult to figure out git URL for clone from
gitweb URL because git:// and http:// are different on many site
including kernel.org.

I've found this enhancement at http://dev.laptop.org/git when I was on
git channel, and thought that it'd be nice if all public gitweb site
show it's git URL on its page.

This patch allow us to change the home link string.  The current
default is "projects" as we all see on gitweb now.

ie. kernel.org might set this variable to "git://git.kernel.org/pub/scm/"

Separate printing difftree in git_commit into separate
git_difftree_body subroutine. Add support for "C" (copied) status. For
"M" and "C" add parameter 'fp' (filename parent) to the "diff" link;
currently not supported by git_blobdiff ("blobdiff" action).

Reindented, realigned, added comments.

True fix for error in mimetype_guess, error introduced in original commit
2d007374 and later fixed temporarily
by commenting out the line that caused error in commit
57bd4d35.

Gitweb now supports mime.types map $mimetypes_file relative to project.

Change git_get_references to include type of ref in the %refs value, which
means putting everything after 'refs/' as a ref name, not only last
part of the name.  Instead of separating refs pointing to the same
object by " / " separator, use anonymous array reference to store all
refs pointing to given object.

Use 'git-ls-remote .' if $projectroot/$project/info/refs does not
exist.  (Perhaps it should be used always.)

Refs are now in separate span elements.  Class is dependent on the ref
type: currently known classes are 'tag', 'head', 'remote', and 'ref'
(last one for HEAD and other refs in the main directory).  There is
encompassing span element of class refs, just in case of unknown ref
type.

This might be considered cleaner separating of git_get_references into
filling %refs hash only, and not taking part in formatting ref marker.

Note that for each ref there are usually two calls to git subroutines:
first to get the type of ref, second to parse ref if ref is of commit
or tag type.

Rename some of subroutines to better reflect what they do.
Some renames were not performed because subroutine name
reflects hash key.

Subroutines name guideline:
* git_ prefix for subroutines related to git commands,
  git repository, or to gitweb actions
* git_get_ prefix for inner subroutines calling git command
  or reading some file in the repository and returning some output
* parse_ prefix for subroutines parsing some text (or reading and
  parsing some text) into hash or list
* format_ prefix for subroutines formatting, post-processing
  or generating some HTML/text fragment
* _get_ infix for subroutines which return result
* _print_ infix for subroutines which print fragment of output
* _body suffix for subroutines which outputs main part (body)
  of related action (usually table)
* _nav suffix for subroutines related to navigation bars
* _div suffix for subroutines returning or printing div element
* subroutine names should not be based on how the result is obtained,
  as this might change easily

Renames performed:
- git_get_referencing => format_ref_marker
- git_get_paging_nav => format_paging_nav
- git_read_head => git_get_head_hash
- git_read_hash => git_get_hash_by_ref
- git_read_description => git_get_project_description
- git_read_projects => git_get_projects_list
- read_info_ref => git_get_references
- git_read_refs => git_get_refs_list
- date_str => parse_date
- git_read_tag => parse_tag
- git_read_commit => parse_commit
- git_blob_plain_mimetype => blob_mimetype
- git_page_nav => git_print_page_nav
- git_header_div => git_print_header_div

git-commit would silently exit if duplicate Signed-off-by
lines were found.  Users of git-commit would not know it,
unless they checked '$?'.  This patch makes git-commit
actually print out a message that nothing was commited
since duplicate Signed-off-lines were found.

Most of the callers except the one in refs.c use the function to
update the index file.  Among the index writers, everybody
except write-tree dies if they cannot open it for writing.

This gives the function an extra argument, to tell it to die
when it cannot create a new file as the lockfile.

The only caller that does not have to die is write-tree, because
updating the index for the cache-tree part is optional and not
being able to do so does not affect the correctness.  I think we
do not have to be so careful and make the failure into die() the
same way as other callers, but that would be a different patch.

If the user tries to apply a patch that was hand-edited in such
a way that it does not apply to the original file recorded on
its "index" line anymore, we did detect the situation but did
not issue an error message that is specific enough.
