Move the Microblaze PVR registers to the end of the CPUMBState
and preserve them during reset. This is similar to what the
QEMU ARM model does with some of it's registers.
This allows the Microblaze PVR registers to only be set once
at realise instead of constantly at reset.

Add new "arg" sub-argument to the --semihosting-config allowing the user
to pass multiple input arguments separately. It is required for example
by UHI semihosting to construct argc and argv.
Also, update ARM semihosting to support new option (at the moment it is
the only target which cares about arguments).
If the semihosting is enabled and no semihosting args have been specified,
then fall back to -kernel/-append. The -append string is split on whitespace
before initializing semihosting.argv[1..n]; this is different from what
QEMU MIPS machines' pseudo-bootloaders do (i.e. argv[1] contains the whole
-append), but is more intuitive from UHI user's point of view and Linux
kernel just does not care as it concatenates argv[1..n] into single cmdline
string anyway.

cp_reg_reset() is called from g_hash_table_foreach() which does not
define a specific ordering of the hash table iteration. Thus doing reset
for registers marked as ALIAS would give an ambiguous result when
resetvalue is different for original and alias registers. Exit
cp_reg_reset() early when passed an alias register. Then clean up alias
register definitions from needless resetvalue and resetfn.
In particular, this fixes a bug in the handling of the PMCR register,
which had different resetvalues for its 32 and 64-bit views.

We use vhostforce to enable vhost even if Guests don't have MSI-X
support and we fall back to QEMU virtio-net.
This gives a very small performance gain, but the disadvantage
is that guest now controls which virtio code is running
(qemu or vhost) so our attack surface is doubled.
This patch will enable vhost unconditionally whenever it's requested.
For compatibility, enable vhost when vhostforce is set, as well.

Few devices have their specialized 'config_write' methods which simply
call 'pci_default_write_config' followed by a 'msix_write_config' or
'msi_write_config' calls, using exact same arguments.
This is unnecessary as 'pci_default_write_config' already invokes
'msi_write_config' and 'msix_write_config'.
Also, since 'pci_default_write_config' is the default 'config_write'
handler, we can simply avoid the registration of these specialized
versions.
