There are numerous QDict functions that have been introduced for and are
used only by the block layer.  Move their declarations into an own
header file to reflect that.

While qdict_extract_subqdict() is in fact used outside of the block
layer (in util/qemu-config.c), it is still a function related very
closely to how the block layer works with nested QDicts, namely by
sometimes flattening them.  Therefore, its declaration is put into this
header as well and util/qemu-config.c includes it with a comment stating
exactly which function it needs.

Although qemu-img creates aligned files (by rounding up), it
must also gracefully handle files that are not sector-aligned.
Test that the bug fixed in the previous patch does not recur.

It's a bit annoying that we can see the (implicit) hole past
the end of the file on to the next sector boundary, so if we
ever reach the point where we report a byte-accurate size rather
than our current behavior of always rounding up, this test will
probably need a slight modification.

Commit a290f085 exposed a latent bug in qemu-img map introduced
during the conversion of block status to be byte-based.  Earlier in
commit 5e344dd8, the internal interface get_block_status() switched
to take byte-based parameters, but still called a sector-based
block layer function; as such, rounding was added in the lone
caller to obey the contract.  However, commit 237d78f8 changed
get_block_status() to truly be byte-based, at which point rounding
to sector boundaries can result in calling bdrv_block_status() with
'bytes == 0' (a coding error) when the boundary between data and a
hole falls mid-sector (true for the past-EOF implicit hole present
in POSIX files).  Fix things by removing the rounding that is now
no longer necessary.

A link property can be set during creation, with
object_property_add_link() and later with object_property_set_link().

add_link() doesn't add a reference to the target object, while
set_link() does.

Furthemore, OBJ_PROP_LINK_UNREF_ON_RELEASE flags, set during add_link,
says whether a reference must be released when the property is destroyed.
This can lead to leaks if the property was later set_link(), as the
added reference is never released.

Instead, rename OBJ_PROP_LINK_UNREF_ON_RELEASE to OBJ_PROP_LINK_STRONG
and use that has an indication on how the link handle reference
management in set_link().

xhci is rock solid meanwhile.  So move it up in the docs and feature it
as prefered usb host adapter, instead of the old shy version saying "you
might want try ...".

While being at it rework the text on ehci and companion controllers too.

  cli: Don't run early event loop if no --preconfig was specified
Signed-off-by: NPeter Maydell <peter.maydell@linaro.org>

By default, the IOMMU model built into the spapr virtual PCI host bridge
supports 4kiB and 64kiB IOMMU page sizes.  However this can be overridden
which may be desirable to allow larger IOMMU page sizes when running a
guest with hugepage backing and passthrough devices.  For that reason a
warning was printed when the device wasn't configured to allow the pagesize
with which guest RAM is backed.

Experience has proven, however, that this message is more confusing than
useful.  Worse it sometimes makes little sense when the host-available page
sizes don't match those available on the guest, which can happen with
a POWER8 guest running on a POWER9 KVM host.

Long term we do want better handling to allow large IOMMU page sizes to be
used, but for now this parameter and warning don't really accomplish it.
So, remove the message, pending a better solution.
