Commit d0d7708b forgot to parse logging for spice chardevs and
virtual consoles. This requires making qemu_chr_parse_common()
non-static. While at it, use a temporary variable to make the
code shorter, as well as reduce the churn when a later patch
alters the layout of simple unions.

these two functions consume too much cpu overhead to
find the RAMBlock by ram address.

After this patch, we can pass the RAMBlock pointer
to them so that they don't need to find the RAMBlock
anymore most of the time. We can get better performance
in address translation processing.

Each RAM memory region has a unique corresponding RAMBlock.
In the current realization, the memory region only stored
the ram_addr which means the offset of RAM address space,
We need to qurey the global ram.list to find the ram block
by ram_addr if we want to get the ram block, which is very
expensive.

Now, we store the RAMBlock pointer into memory region
structure. So, if we know the mr, we can easily get the
RAMBlock.

When dump-guest-memory is requested with detach flag, after its
return, user could query its status using "query-dump" command (with
no argument). The result contains:

- status: current dump status
- completed: bytes written in the latest dump
- total: bytes to write in the latest dump

From completed and total, we could know how much work
finished by calculating:

  100.0 * completed / total (%)

The SD spec for ACMD41 says that a zero argument is an "inquiry"
ACMD41, which does not start initialisation and is used only for
retrieving the OCR. However, Tianocore EDK2 (UEFI) has a bug [1]: it
first sends an inquiry (zero) ACMD41. If that first request returns an
OCR value with the power up bit (0x80000000) set, it assumes the card
is ready and continues, leaving the card in the wrong state. (My
assumption is that this works on hardware, because no real card is
immediately powered up upon reset.)

This change models a delay of 0.5ms from the first ACMD41 to the power
being up. However, it also immediately sets the power on upon seeing a
non-zero (non-enquiry) ACMD41. This speeds up UEFI boot, it should
also account for guests that simply delay after card reset and then
issue an ACMD41 that they expect will succeed.

card is ready")

Add a QOM bus for SD cards to plug in to.

Note that since sd_enable() is used only by one board and there
only as part of a broken implementation, we do not provide it in
the SDBus API (but instead add a warning comment about the old
function). Whoever converts OMAP and the nseries boards to QOM
will need to either implement the card switch properly or move
the enable hack into the OMAP MMC controller model.

In the SDBus API, the old-style use of sd_set_cb to register some
qemu_irqs for notification of card insertion and write-protect
toggling is replaced with methods in the SDBusClass which the
card calls on status changes and methods in the SDClass which
the controller can call to find out the current status. The
query methods will allow us to remove the abuse of the 'register
irqs' API by controllers in their reset methods to trigger
the card to tell them about the current status again.
