The virtio serial specification requres that the values in the config
space are encoded in native endian of the guest.
The qemu virtio-serial code did not do conversion to the guest endian
format what caused problems when host and guest use different format.
This patch corrects the qemu side, correctly doing host-native <->
guest-native conversions when accessing the config space. This won't
break any setups that aren't already broken, and fixes the case
of different host and guest endianness.

Some frontends know when the guest has opened the "channel" and is actively
listening to it, for example virtio-serial. This patch adds 2 new qemu-chardev
functions which can be used by frontends to signal guest open / close, and
allows interested backends to listen to this.

target-arm: fix LDMIA bug on page boundary
When consecutive memory locations are on page boundary, a base register may be
loaded before page fault occurs. After page fault handling, it losts the memory
location information. To solve this problem, loading a base register has to put back.

So far we set IRR for edge IRQs even if the pin is masked. If the guest
later on unmasks and switches the pin to level-triggered mode, irr will
remain set, causing an IRQ storm. The point is that setting IRR is not
correct in this case according to the spec, and avoiding this resolves
the issue.

The -virtfs option creates an fsdev representing the pass-through file
system and a guest-visible virtio-9p-pci device that can access this
file system. This patch replaces the string manipulation used to build
and reparse option lists with direct QemuOpts calls. Removing the
string manipulation code makes it easier to maintain and less error
prone.
An error message is also updated to use "mount_tag" instead of
"mnt_tag".

Some commands are supposed to report a Not Ready Condition (i.e. they require
a medium to be present in order to execute successfully). Instead of
duplicating the check in each command implementation, let's add a flag and
check it before calling the command.
This patch only converts existing checks, it does not introduce new checks for
any of the other commands that can/should report a Not Ready Condition.

block_mig_state.total_time is currently the sum of the read request
latencies. This is not very accurate because block migration uses aio and
so several requests can be submitted at once. Bandwidth should be computed
with wall-clock time, not by adding the latencies. In this case,
"total_time" has a higher value than it should, and so the computed
bandwidth is lower than it is in reality. This means that migration can
take longer than it needs to.
However, we don't want to use pure wall-clock time here. We are computing
bandwidth in the asynchronous phase, where the migration repeatedly wakes
up and sends some aio requests. The computed bandwidth will be used for
synchronous transfer.

MMC-5 Table F.1 lists errors that can be thrown for the TEST_UNIT_READY
command. Going from medium not ready to medium ready states is
communicated by throwing an error.
This adds the missing 'tray opened' event that we fail to report to
guests. After doing this, older Linux guests properly revalidate a disc
on the change command. HSM violation errors, which caused Linux guests
to do a soft-reset of the link, also go away:

QEMU can drop a backing file so that an image file no longer depends on
the backing file, but this feature has not been exposed in qemu-img.
This is useful in an image streaming usecase or when an image file has
been fully allocated and no reads can hit the backing file anymore.
Since the dropping the backing file can make the image unusable, only
allow this when the unsafe flag has been set.

Work around a SPARC glibc bug which caused the epoll_create1 configure
test to wrongly claim that the function was present. Some versions of
SPARC glibc provided the function in the library but didn't declare
it in the include file; the result is that gcc warns about an implicit
declaration but a link succeeds. So we reference the function as a
value rather than a function call to induce a compile time error
if the declaration was not present.
