NC-SI (Network Controller Sideband Interface) enables a BMC to manage

Exynos4210 has four SD/MMC controllers supporting:
 - SD Standard Host Specification Version 2.0,
 - MMC Specification Version 4.3,
 - SDIO Card Specification Version 2.0,
 - DMA and ADMA.

Add emulation of SDHCI devices which allows accessing storage through SD
cards. Differences from real hardware:
 - Devices are shipped with eMMC memory, not SD card.
 - The Exynos4210 SDHCI has few more registers, e.g. for
   controlling the clocks, additional status (0x80, 0x84, 0x8c). These
   are not implemented.

For the tests that use the common.qemu functions for running a QEMU
process, _cleanup_qemu must be called in the exit function.

If it is not, if the qemu process aborts, then not all of the droppings
are cleaned up (e.g. pidfile, fifos).

This updates those tests that did not have a cleanup in qemu-iotests.

A few block drivers will set the BDS read_only flag from their
.bdrv_open() function.  This means the bs->read_only flag could
be set after we enable copy_on_read, as the BDRV_O_COPY_ON_READ
flag check occurs prior to the call to bdrv->bdrv_open().

This adds an error return to bdrv_set_read_only(), and an error will be
return if we try to set the BDS to read_only while copy_on_read is
enabled.

This patch also changes the behavior of vvfat.  Before, vvfat could
override the drive 'readonly' flag with its own, internal 'rw' flag.

For instance, this -drive parameter would result in a writable image:

"-drive format=vvfat,dir=/tmp/vvfat,rw,if=virtio,readonly=on"

This is not correct.  Now, attempting to use the above -drive parameter
will result in an error (i.e., 'rw' is incompatible with 'readonly=on').

This is to allow clients to initialise these without failing as long
as no 2D engine function is called that would use the written value.
Saved values are not used yet (may get used when more of 2D engine is
added sometimes) and clients normally only write to most of these
registers, nothing is known to ever read them but they are documented
as read/write so also implement read for these.

Rework HWC handling to simplify it and fix cursor not updating on

We only emulate the sysbus device in its default LE mode and PCI is LE
as well so specify this for registers and framebuffer memory.

Note that though the Linux kernel driver has code which claims to
handle both big and little endian, it is obviously bogus for 16 bit
and cannot be trusted as a source of information on the framebuffer
pixel format. This is our best guess about device behaviour based on
the specs and testing with MorphOS that is known to work on real HW.
