Merge remote-tracking branch 'remotes/bonzini/tags/for-upstream' into staging

* CAN bus (will be under network maintainner)
* scsi-block opblockers (myself)
* Dirty log bitmap cleanup (myself)
* SDHCI improvements and tests (Philippe)
* HAX support for larger guest sizese (Yu Ning)

* remotes/bonzini/tags/for-upstream: (48 commits)
  travis: use libgcc-4.8-dev (libgcc-6-dev is not available on Ubuntu 14.04)
  memory: unify loops to sync dirty log bitmap
  memory: hide memory_region_sync_dirty_bitmap behind DirtyBitmapSnapshot
  memory: remove memory_region_test_and_clear_dirty
  g364fb: switch to using DirtyBitmapSnapshot
  sdhci: add Spec v4.2 register definitions
  sdhci: add a check_capab_v3() qtest
  sdhci: check Spec v3 capabilities qtest
  hw/arm/xilinx_zynqmp: enable the UHS-I mode
  hw/arm/xilinx_zynqmp: fix the capabilities/spec version to match the datasheet
  hw/arm/fsl-imx6: implement SDHCI Spec. v3
  hw/arm/bcm2835_peripherals: change maximum block size to 1kB
  hw/arm/bcm2835_peripherals: implement SDHCI Spec v3
  sdhci: implement CMD/DAT[] fields in the Present State register
  sdhci: implement UHS-I voltage switch
  sdbus: add trace events
  sdhci: implement the Host Control 2 register (tuning sequence)
  sdhci: rename the hostctl1 register
  sdhci: add support for v3 capabilities
  hw/arm/xilinx_zynq: fix the capabilities register to match the datasheet
  ...
