71fe945da3 Prevent unbounded listener growth on SkPixelRefs.
Use SkIDChangeListener and update GrBitmapTextureMaker to add listener
to key to deregister if texture is purged before genID changes.

Add a common listener list implementation and replace existing lists.

c0bd9f9fe5 rewrite includes to not need so much -Ifoo
Current strategy: everything from the top

Things to look at first are the manual changes:

   - added tools/rewrite_includes.py
   - removed -Idirectives from BUILD.gn
   - various compile.sh simplifications
   - tweak tools/embed_resources.py
   - update gn/find_headers.py to write paths from the top
   - update gn/gn_to_bp.py SkUserConfig.h layout
     so that #include "include/config/SkUserConfig.h" always
     gets the header we want.

I think they are creating a cairo surface, but it has no pixels (zero size?). In this CL, if I see no pixels, I ignore the call-back which is used to free the surface (doh).

This fixes every case where virtual and SK_OVERRIDE were on the same line,
which should be the bulk of cases.  We'll have to manually clean up the rest
over time unless I level up in regexes.

for f in (find . -type f); perl -p -i -e 's/virtual (.*)SK_OVERRIDE/\1SK_OVERRIDE/g' $f; end

2ebc10dd12 Revert "Revert "Revert "PixelRef now returns (nearly) everything that is currently in SkBitmap. The goal is to refactor bitmap later to remove redundancy, and more interestingly, remove the chance for a disconnect between the actual (pixelref) rowbytes and config, and the one claimed by the bitmap."""
This reverts commit 5f035e90d6dea0139a4f204b634e7b7b3b4976d7.

Reverting because it breaks chrome/blink due to new SkPixelRef constructor arg.

50a3043194 We want to give SkPixelRef a way to signal over to GrResourceCache that it's become pointless to keep around textures based on that SkPixelRef when its pixels change, so that it can be a good citizen and free those textures.
This adds an invalidation listener mechanism to SkPixelRef to let it send this message while still staying ignorant of who's listening.

These messages are tricky to deliver.  The SkPixelRefs they originates from and the GrResourceCaches they ultimately end up at may be on different threads; neither class is threadsafe; their object lifetimes are totally independent; it's a many-senders-to-many-receivers relation; and neither codebase should really know about the other.

So I've added a per-message-type global message bus to broadcast messages to threadsafe inboxes.  Anyone can post() a message, which will show up in all the inboxes of that type, read whenever the inbox's owner calls poll().  The implementation is _dumb_; it can be improved in several dimensions (inbox size limits, lock-free message delivery) if we find the need.

I took some care to make sure not to send the invalidation message for any SkPixelRef that's sharing a generation ID with another SkPixelRef.
