The code to print blocks in now in theme layout.php files. (Or in
moodle_core_renderer::handle_legacy_theme)
Code for printing blocks everywhere else has been stripped out.

The way the HTML for a block instance is generated has been cleaned
up a lot. Now, the block_instance generates a block_contents
object which gives a structured representation of the block,
and then $OUTPUT->block builds all the HTML from that.
How theme config.php files specify the layout template and block
regions by page general type has been changed to be even more flexible.
Further refinement for how the theme and block code gets initialised.
Ability for scrits to add 'pretend blocks' to the page. That is,
things that look like blocks, but are not normal block_instances.
(Like the add a new block UI.)
Things that are still broken:
* some pages in lesson, quiz and resource. I'm working on it.
* lots of developer debug notices pointing out things that
need to be updated.
There is a new implementation of require_js in lib/deprecatedlib.php,
based on $PAGE->requires.
There were a few other recently introduced functions in lib/weblib.php,
namely print_js_call, print_delayed_js_call, print_js_config and
standard_js_config. These have been removed, since they were never in
a stable branch, and all the places that used them have been changed
to use the newer $PAGE->requires->... methods.
get_require_js_code is also gone, and the evil places that were calling
it, even though it is an internal function, have been fixed.
Also, I made some minor improvements to the code I committed yesterday
for MDL-16695.
All that remains is to update all the places in core code that are
still using require_js.
(This commit also fixes the problem where the admin tree would not
start with the right categories expanded.)
This new class does the work that require_js used to do, and more.
It can track a number of different things that may be required to
be output somewhere on the page, including:
* Links to JS files
* Links to CSS files
* Links to YUI libraries (this class knows about the dependancies between the different libs).
* Skip links that go from the top of <body> to various places in the content.
* Calls to JavaScript functions (for example to initialise things)
* Bits of data from PHP that need to be available to JavaScript
* As a special case of that, an easy way to pass language strings to JS.
The new API looks like
$PAGE->requires->css('mod/mymod/styles.css');
$PAGE->requires->js('mod/mymod/script.js');
$PAGE->requires->js('mod/mymod/small_but_urgent.js')->in_head();
$PAGE->requires->js_function_call('init_mymod', array($data))->on_dom_ready();
$PAGE->requires is the canonical instances of this new class.
The commit also includes unit tests, and hopefully the PHP doc comments are
clear enough that it is easy to understand.
