Instead of simply propagating an error verbatim, we sometimes want to
add to its message, like this:
frobnicate(arg, &err);
error_setg(errp, "Can't frobnicate %s: %s",
arg, error_get_pretty(err));
error_free(err);
This is suboptimal, because it loses err's hint (if any). Moreover,
when errp is &error_abort or is subsequently propagated to
&error_abort, the abort message points to the place where we last
added to the error, not to the place where it originated.
To avoid these issues, provide means to add to an error's message in
place:
frobnicate(arg, errp);
error_prepend(errp, "Can't frobnicate %s: ", arg);
Likewise, reporting an error like
frobnicate(arg, &err);
error_report("Can't frobnicate %s: %s", arg, error_get_pretty(err));
can lose err's hint. To avoid:
error_reportf_err(err, "Can't frobnicate %s: ", arg);
The next commits will put these functions to use.

and qemu_get_aio_context() failure in one conditional. In fact,
qemu_get_aio_context() can fail only after qemu_init_main_loop()
failed.
Simplify accordingly: check for qemu_init_main_loop() error directly,
without bothering to improve its error message. Call
qemu_get_aio_context() only when qemu_get_aio_context() succeeded. It
can't fail then, so no need to check.

We can have at most one ISA bus. If you try to create another one,
isa_bus_new() complains to stderr and returns null.
isa_bus_new() is called in two contexts, machine's init() and device's
realize() methods. Since complaining to stderr is not proper in the
latter context, convert isa_bus_new() to Error.
Machine's init():
* mips_jazz_init(), called from the init() methods of machines
"magnum" and "pica"
* mips_r4k_init(), the init() method of machine "mips"
* pc_init1() called from the init() methods of non-q35 PC machines
* typhoon_init(), called from clipper_init(), the init() method of
machine "clipper"
These callers always create the first ISA bus, hence isa_bus_new()
can't fail. Simply pass &error_abort.
Device's realize():
* i82378_realize(), of PCI device "i82378"
* ich9_lpc_realize(), of PCI device "ICH9-LPC"
* pci_ebus_realize(), of PCI device "ebus"
* piix3_realize(), of PCI device "pci-piix3", abstract parent of
"PIIX3" and "PIIX3-xen"
* piix4_realize(), of PCI device "PIIX4"
* vt82c686b_realize(), of PCI device "VT82C686B"
Propagate the error. Note that these devices are typically created
only by machine init() methods with qdev_init_nofail() or similar. If
we screwed up and created an ISA bus before that call, we now give up
right away. Before, we'd hobble on, and typically die in
isa_bus_irqs(). Similar if someone finds a way to hot-plug one of
these critters.

Cleanups mostly isolating virtio related details into separate files. This
is done to enable easy addition of Xen transport for VirtFS.
The changes include:
1. Rename a bunch of files and functions to make clear they are generic.
2. disentangle virtio transport code and generic 9pfs code.
3. Some function name clean-up.

The VIXL code includes some equality comparisons between signed
and unsigned types. Modern gcc and clang do not complain about
these, but older versions of gcc such as gcc 4.6.3 do. Since
libvixl is an upstream library, the simplest approach is to
suppress the warnings by applying -Wno-sign-compare to the
relevant files.
(GCC 4.6 is not quite yet irrelevant for us; it is the gcc
shipped with Ubuntu Precise, for example, which is an LTS
release not yet out of its support period.)

V9fsState now only contains generic fields. Introduce V9fsVirtioState
for virtio transport. Change virtio-pci and virtio-ccw to use
V9fsVirtioState.

Simple I/O tests for DMA and PIO pathways in the AHCI HBA.
I believe at this point in time all of the common, major IO pathways
in BMDMA and AHCI are covered by qtests now.

add ahci_exec, which is a standard purpose flexible command dispatcher
and tester for the AHCI device. The intent is to eventually cut down on
the absurd amount of boilerplate inside of the AHCI qtest.

These variants try to set a data offset, even if you don't specify one.
In the cases where the offset is zero and it's a nondata command, just
ignore the instruction.

As part of streamlining the AHCI tests interface, it'd be nice
if specying a size of zero could be handled without special branches
and the allocator could handle this special case gracefully.
This lets me use the "ahci_io" macros for non-data commands, too,
which moves me forward towards shepherding all AHCI qtests into
a common set of commands in a unified pipeline.

ATAPI commands are, unfortunately, weird in that they can
be either DMA or PIO depending on a header bit. In order to
accommodate them, I'll need to make AHCI command properties
mutable so we can toggle between which "flavor" of ATAPI command
we want to test.
The default ATAPI transfer mechanism is PIO and the default
properties are adjusted accordingly.

Add pathways to tolerate ATAPI commands.
Notably, unlike ATA, each SCSI command's layout is a little different,
so support will have to be patched in for each command as we want to
test them in e.g. ahci_command_set_sizes and ahci_command_set_offset.
For now, I'm adding support for 0x28, READ (10).
