t0108: Avoid unnecessary fork()

Use `git rev-list --max-parents=0 HEAD` instead of `git rev-list HEAD |
tail -1` to get the root commit. This works since Git 1.7.4.2.

ui-diff: Use diff_tree_sha1() for raw diff formatting

Use argv_array in place of vector

Instead of using our own vector implementation, use argv_array from Git
which has been specifically designed for dynamic size argv arrays.

Drop vector.h and vector.c which are no longer needed.

* Remove unneeded static strings.

plain: don't append charset for binary MIME types

When outputting the Content-Type HTTP header we print the MIME type and
then append "; charset=<charset>" if the charset variable is non-null.

We don't want a charset when we have selected "application/octet-stream"
or when the user has specified a custom MIME type, since they may have
specified their own charset.  To avoid this, make sure we set the page's
charset to NULL in ui-plain before we generate the HTTP headers.

Reduce line number bloat, fix hover effect

Currently line numbers look like (for blob view and sdiff respectively):

    <a class='no' id='n68' name='n68' href='#n68'>68</a>
    <td class='lineno'><a class='no' href='...#n1' id='n1' name='n1'>1</a></td>

name=".." is unnecessary if the id attribute is set (this even applies
to IE6), so drop it. (aside, in HTML5, the name attribute is gone.)

The line number links can be selected through their parent classes, no
need for another class "no", so drop it too.

For a file with 2000 lines, this yields a saving of 40% (29% gzipped).

While at it, fix the hover effect of line numbers: now the line number
get a black background as was intended.
