Introduce support for GTree migration. A custom save/restore
is implemented. Each item is made of a key and a data.
If the key is a pointer to an object, 2 VMSDs are passed into
the GTree VMStateField.
When putting the items, the tree is traversed in sorted order by
g_tree_foreach.
On the get() path, gtrees must be allocated using the proper
key compare, key destroy and value destroy. This must be handled
beforehand, for example in a pre_load method.
Tests are added to test save/dump of structs containing gtrees
including the virtio-iommu domain/mappings scenario.

The test-vmstate test is a bit chatty because it triggers various
expected failure scenarios and the code in question uses error_report
instead of accepting 'Error **errp' parameters. To silence this test the
stubs for error_vprintf() were changed to send errors via
g_test_message() instead of stderr:

Unfortunately this change has global impact across the entire test suite
and means that when tests fail for unexpected reasons, the message is
not displayed on stderr. eg when using &error_abort in a call the test
merely prints
Unexpected error in qcrypto_tls_session_check_certificate() at crypto/tlssession.c:280:
and the actual error message is hidden, making it impossible to diagnose
the failure. This is especially problematic in CI or build systems where
it isn't possible to easily pass the --debug-log flag to tests and
re-run with the test log visible.
This change makes the previous big hammer much more nuanced, providing a
flag in the stub error_vprintf() that can used on a per-test basis to
silence the errors. Only the test-vmstate silences errors initially.

Commit message fix up as Peter's review
Modify the pre_save method on VMStateDescription to return an int
rather than void so that it potentially can fail.
Changed zillions of devices to make them return 0; the only
case I've made it return non-0 is hw/intc/s390_flic_kvm.c that already
had an error_report/return case.
Note: If you add an error exit in your pre_save you must emit
an error_report to say why.

The coroutine files are currently referenced by the block-obj-y
variable. The coroutine functionality though is already used by
more than just the block code. eg migration code uses coroutine
yield. In the future the I/O channel code will also use the
coroutine yield functionality. Since the coroutine code is nicely
self-contained it can be easily built as part of the libqemuutil.a
library, making it widely available.
The headers are also moved into include/qemu, instead of the
include/block directory, since they are now part of the util
codebase, and the impl was never in the block/ directory
either.

One of the annoyances of the current migration format is the fact that
it's not self-describing. In fact, it's not properly describing at all.
Some code randomly scattered throughout QEMU elaborates roughly how to
read and write a stream of bytes.
We discussed an idea during KVM Forum 2013 to add a JSON description of
the migration protocol itself to the migration stream. This patch
adds a section after the VM_END migration end marker that contains
description data on what the device sections of the stream are composed of.
This approach is backwards compatible with any QEMU version reading the
stream, because QEMU just stops reading after the VM_END marker and ignores
any data following it.
With an additional external program this allows us to decipher the
contents of any migration stream and hopefully make migration bugs easier
to track down.
