Patch for Named Destinations

[St...@gmx.de]

Hi all.

I patched the fop-0_20_2-maintain branch (21-01-2003, approx. 20:00 CET) to
have named destinations. The patch allows to link to other PDF-Documents by
the following syntax:

<fo:basic-link external-destination="handbuch-fop.pdf#dest=xyz">external
link to named destination</fo:basic-link>
<fo:basic-link external-destination="handbuch-fop.pdf#page=5">external link
to page</fo:basic-link>

This part is based on work by Bernd Brandstetter published recently in the
fop-user-list. In addition, the patch allows to define named destinations by a
new extension element with the following syntax:

<fox:destination xmlns:fox="http://xml.apache.org/fop/extensions"
destination-name="xyz" internal-destination="N40001A"/>

The destination-name attribute must correspond to the value used in the link
(dest=xyz above). The fox:destination elements must be children of the
fo:root element. In addition, they must not be the last children, i.e. they should
be placed right after the fo:root element opened. (Otherwise they get not
processed for whaterever reason this is). This part is based on work by Lloyed
McKenzie that was published in the fop-dev-list in November 2001.

Two additional classes are neccessary:

1. The destination extension element (org.apache.fop.extensions.Destination)
2. The PDF element for the destination (org.apache.fop.pdf.PDFDestination)
