Bug: 27286867
WindowManager has committed to stopped state
controlling the lifecycle of the Surface, so
make that a first-class thing in HWUI as well.
This makes it more resistent to things like
a rogue updateSurface() happening while mStopped=true,
leading to bad things down the line. Instead let
the surface be changed/updated as often as desired,
and just block any attempt to draw on that surface.
Also removes some unnecessary makeCurrent()s, as
EglManager ensures that we *always* have a valid
GL context now (using a pbuffer surface if there is
no window surface set)

If the system/app is slow, it might take too long to
stop drawing. Switch the ordering of destroying stuff so
that we switch to the pbuffer surface first, then do
cleanup

Not using EGL_SWAP_BEHAVIOR_PRESERVED_BIT as config attribute for
eglChooseConfig doesn't automatically mean the swap behavior is buffer
destroyed. This is driver implementation specific and on some hw this
can still be buffer preserved. Make sure it is buffer destroyed by
explicitly setting it for every new surface when requested.

If eglSwapBuffers is called but the under surface was destroyed,
the EGL_BAD_NATIVE_WINDOW error may also be generated according
to the EGL spec 1.4.
This really shouldn't happen from the upper, but add the graceful
handling of this case also.

Bug: 21753739
Includes a revert of 13d1b4ab10fbee5e81a2ba1ac59cfae1e51d3ef0
as that only supported EGL_EXT_buffer_age
Change-Id: Ia86a47d19e3355c067934d7764c330b640c6958d
EGL_EXT_buffer_age is better than EGL_BUFFER_PRESERVED
because it can save memory bandwidth used to blit
back buffer into front buffer.

WindowManager may decide to yank the surface at any point, so
attempt to kinda handle this

Adds remaining missing overrides and nullptr usages, missed due to
an extreme failure in tool usage.

Bug: 18317479
RenderNode::prepareSubTree calls prefetchAndMarkInUse
on every bitmapResoruce in the DisplayList. However,
this resulted in textures being uploaded for bitmaps
that would be drawn from the AssetAtlas instead.
To fix this we teach TextureCache about the AssetAtlas
so that calls to TextureCache return the Texture from
AssetAtlas if it exists. Thus usage of AssetAtlas
is now purely to allow for further optimizations via
draw merging instead of a requirement to get
any benefit at all.

* Switch Layer to be VirtualLightRefBase instead of
Caches' side-channel ref-counting
* Include active layers in gfxinfo dump
* Run gfxinfo dump on the correct thread
* Dump gfxinfo on Layer creation failure

Don't use EGL_SWAP_BUFFER_PRESERVED on surfaces that will
never benefit. Also clean up some confusing naming

Narrow the use of #include directives in hwui, replacing with forward
declarations where straightforward. Speeds compiles; doesn't do any
restructuring of code.
