Changes

Bug 560602 - Switch to EPL version 2.0
Update license declaration in extension schema definitions
Remove outdated extension point documentation and instead make Tycho/PDE
regenerate the extension point documentation at build time, so it always
contains up to date copyright and license notices.
Use tycho javadoc plugin to generate javadoc and correct table of
contents for javadoc in the doc bundle
Misc other updates to doc bundle, including adding a link to the
copyright notices file and removing duplicate table of contents entries,
linking correctly to JDK types from ECF javadoc, fix broken external
links in infro pages and pre-generating search indexes
