cppcheck reported memory leaks and mismatched g_malloc() with free()
instead of g_free().
Fix these errors.

Contains the I/O status for the given device. The key is only present
if the device supports it and the VM is configured to stop on errors.
Please, check the documentation being added in this commit for more
information.

This commit adds support to the BlockDriverState type to keep track
of devices' I/O status.
There are three possible status: BDRV_IOS_OK (no error), BDRV_IOS_ENOSPC
(no space error) and BDRV_IOS_FAILED (any other error). The distinction
between no space and other errors is important because a management
application may want to watch for no space in order to extend the
space assigned to the VM and put it to run again.
Qemu devices supporting the I/O status feature have to enable it
explicitly by calling bdrv_iostatus_enable() _and_ have to be
configured to stop the VM on errors (ie. werror=stop|enospc or
rerror=stop).
In case of multiple errors being triggered in sequence only the first
one is stored. The I/O status is always reset to BDRV_IOS_OK when the
'cont' command is issued.
Next commits will add support to some devices and extend the
query-block/info block commands to return the I/O status information.

The error handling order was in the wrong order, so that either the ACB would
be leaked or the counter would be decremented when it shouldn't.

Allow to resize images that reside on host devices up to the available
space. This allows to grow images after resizing the device manually or
vice versa.

The only user of ISADevice.ioports is isabus_get_fw_dev_path, and it
only looks at the first entry of the array. Which suggests that this
entire array+sort operation can be replaced by a simple minimum.

Clean up versatile_pci to expose the various PCI mmio regions
properly as separate mmio regions rather than as a single mmio
which uses callbacks to map and unmap everything.

The alarm is a fully general one-shot time comparator, which will be
usable under Linux as a hrtimer source. It's much more flexible than
the RTC source available on real hardware.
The wall clock allows the guest access to the host timekeeping. Much
like the KVM wall clock source for other guests.
Both are accessed via the PALcode Cserve entry point.

This is a DP264 variant, SMP capable, no unusual hardware present.
The emulation does not currently include any PCI IOMMU code.
Hopefully the generic support for that can be merged to HEAD soon.

* 'for-upstream' of git://git.serverraum.org/git/mw/qemu-lm32:
milkymist: new interrupt map
milkymist_uart: support new core version
lm32: add missing qemu_init_vcpu() call
Remove the unused function tcg_out_addi() from the s390 TCG backend;
this brings it into line with other backends.
