Add support for Mac NPAPI drawing model negotiation, along with a stub
of Quickdraw model support (work in progress--QD plugins no longer
crash, but they don't draw correctly either).

Superseded by http://codereview.chromium.org/211031

Line 867: plugin->set_drawing_model(model);
Shouldn't this be outside the if, so we get the negotiation, and just have the
error value differ for now??

Line 212: (SInt32) CGBitmapContextGetBytesPerRow(context));
These two lines should be static_cast<>s

Line 337: paint_event.modifiers = 0;
The paint_event code is mostly duplicated; maybe split out a helper function to
create the NPEvent, and have it only conditionalize the message field.

New diffs with a change that didn't make it into 211031.
