This new test verifies that VMDK backing file reads fail when the

VMDK performs a probing check in vmdk_co_create_opts() to prevent the
user from assigning non-VMDK files as a backing file, because it only
supports VMDK backing files. However, with the @backing runtime option,
it is possible to assign arbitrary nodes as backing nodes, regardless of
what the image header says. Therefore, VMDK may not just access backing
nodes assuming they are VMDK nodes -- which it does, because it needs to
compare the backing file's CID with the overlay's parentCID value, and
naturally the backing file only has a CID when it's a VMDK file.
Instead, it should report the CID of non-VMDK backing files not to match
the overlay because clearly a non-present CID does not match.
Without this change, vmdk_read_cid() reads from the backing file's
bs->file, which may be NULL (in which case we get a segfault). Also, it
interprets bs->opaque as a BDRVVmdkState and then reads from the
.desc_offset field, which usually will just return some arbitrary value
which then results in either garbage to be read, or bdrv_pread() to
return an error, both of which result in a non-matching CID to be
reported.
(In a very unlikely case, we could read something that looks like a
VMDK descriptor, and then get a CID which might actually match. But
that is highly unlikely, and the only result would be that VMDK accepts
the backing file which is not too bad (albeit unintentional).)
((And in theory, the seek to .desc_offset might leak data from another
block driver's opaque object. But then again, the user should realize
very quickly that a non-VMDK backing file does not work (because the
read will very likely fail, due to the reasons given above), so this
should not be exploitable.))

This fixes a record-replay regression introduced by 95590e2
("translate-all: discard TB when tb_link_page returns an existing
matching TB", 2018-06-15). The problem is that code using CF_NOCACHE
assumes that the TB returned from tb_gen_code is always a
newly-generated one. This assumption, however, was broken in
the aforementioned commit.
Fix it by honouring CF_NOCACHE, so that tb_gen_code always
returns a newly-generated TB when CF_NOCACHE is passed to it.
Do this by avoiding the TB hash table if CF_NOCACHE is set.

DeviceClass::reset models a "cold power-on" reset which can
also be used to powercycle a device; but there is no "hot reset"
(a.k.a. soft-reset) method available.
The OMAP MMC Power-Up Control bit is not designed to powercycle
a card, but to disable it without powering it off (pseudo-reset):
Multimedia Card (MMC/SD/SDIO) Interface [SPRU765A]
MMC_CON[11] Power-Up Control (POW)
This bit must be set to 1 before any valid transaction to either
MMC/SD or SPI memory cards.
When 1, the card is considered powered-up and the controller core
is enabled.
When 0, the card is considered powered-down (system dependent),
and the controller core logic is in pseudo-reset state. This is,
the MMC_STAT flags and the FIFO pointers are reset, any access to
MMC_DATA[DATA] has no effect, a write into the MMC.CMD register
is ignored, and a setting of MMC_SPI[STR] to 1 is ignored.
By splitting the 'pseudo-reset' code out of the 'power-on' reset
function, this patch fixes a latent bug in omap_mmc_write(MMC_CON)i
recently exposed by ecd219f7ab.

sam460ex_load_device_tree() handles nearly all possible errors by simply
exiting (within helper functions and macros). It handles two early error
cases by returning an error.
There's no particular point to this, so make it handle those directly as
well, removing the need for the caller to handle a failure. As a bonus it
gives us more specific error messages.

In a couple of places sam460ex_load_device_tree() calls "raw" libfdt
functions which can fail, but doesn't check for error codes. At best,
if these fail the guest will be silently started in a non-standard state,
