SurfaceFlinger: Change to support framebuffer flip for 2D blitters

- Surfaceflinger does not flip framebuffers when there are
  no layers marked for HWC_FRAMEBUFFER
- This change checks for the HWC_BLIT flag and will request a flip
  to a new FB_TARGET buffer even if there are no FRAMEBUFFER layers

surfaceflinger: Apply bugfixes to the correct hwc code paths

Changes I2deaf2ed101e8ea76708862a6bb67751b6078794 and
I1cb44389a05c9ec049d7f0d39c288feccb11a91c, both meant to deal
with corner-case layer states, were mistakenly merged into
the pre-1.0-hwc code paths. Move them to their intended locations

libgui: Bring back support for mHeap-based screenshots

Older graphics libraries throw a hissy fit when trying to lock
buffers for Surface-based screenshots, on at least Tegra2/3 and
Exynos4 hardware.

This patch depends on the BOARD_USE_MHEAP_SCREENSHOT board flag
and requires the ro.bq.gpu_to_cpu_unsupported property set to 1
in order to work.

Do not just silently fail if surface creation fails

Some apps do not check if they actually got a surface (e.g. bootanimation)
So this helps the track crashes down to the cause.
