Bug 906643. Part 1: Add nsRefreshDriver::Add/Remove/PostRefreshObserver so we can receive notifications when a refresh has occurred, without triggering one. r=dbaron

Bug 906643. Part 5: Add nsIPresShell::AddPostRefreshObserver/RemovePostRefreshObserver. r=mats
Bug 906643. Part 5.2: Add gfxFont::GlyphChangeObserver. r=jfkthame
Bug 906643. Part 5.6: Make nsTextFrames register themselves as observers when they have animated glyphs (but only the text frames that are the start of a run of continuations using a particulr textrun). r=jfkthame
Bug 906643. Part 6: Add gfxFontEntry::NotifyGlyphsChanged, which calls new gfxFont::NotifyGlyphsChanged, which calls new gfxGlyphExtents::NotifyGlyphsChanged; these methods flush out existing glyph extents and notify all affected gfxUserFontGroups of the glyph changes. r=jfkthame
Bug 906643. Part 7: Hook up animation support for gfxSVGGlyphs. r=jfkthame
There's a few things mashed together in this patch:
-- Enable animations in glyph documents
-- Make gfxSVGGlyphsDocument monitor the document's refresh driver to detect
updates
-- Forward updates to the gfxFontEntry
Bug 909922 - don't pragma pack ipc message headers; r=bent

The IPC::Message header is surrounded by:

#pragma pack(push,2)
...
#pragma pack(pop)

which (at least on GCC) specifies that structure members defined lexically
within the pragma should be two-byte aligned, rather than the ABI's declared
alignment.

But for IPC::Message::Header, this is a silly requirement, as everything there
is four bytes; there's no reason to pack the members any tighter.  And packing
tighter means that strict alignment platforms (like ARM) need to use more
complex code for something as simple as storing to one of the members--like
when we set a message's request ID, over and over and over.  The current code
for setting a message's request ID on ARM looks like:

     264:	6863      	ldr	r3, [r4, #4]
     266:	696a      	ldr	r2, [r5, #20]
     268:	809a      	strh	r2, [r3, #4]
     26a:	0c12      	lsrs	r2, r2, #16
     26c:	80da      	strh	r2, [r3, #6]

With the patch, it looks like:

     264:	6863      	ldr	r3, [r4, #4]
     266:	696a      	ldr	r2, [r5, #20]
     268:	605a      	str	r2, [r3, #4]

Only four bytes, but multiplied over several hundred set_routing_id calls, it
saves some code size and runtime.  I verified that the header's length doesn't
change by looking at debug information.
