Convert the omap_intc devices to qdev. This includes adding
a 'revision' property which will be needed for omap3.
The bulk of this patch is the replacement of "s->irq[x][y]"
with "qdev_get_gpio_in(s->ih[x], y)" now that the interrupt
controller exposes its input lines as qdev gpio inputs.
The devices are named "omap-intc" and "omap2-intc", following
the filename and the OMAP2/3 hardware names, although some
internal functions are still named "omap_inth_*".

The previous behaviour was to finish AIOCBs inside curl_aio_readv()
if the data was cached. This caused the following failed assertion
at hw/ide/pci.c:314: bmdma_cmd_writeb
"Assertion `bm->bus->dma->aiocb == ((void *)0)' failed."
By scheduling a QEMUBH and performing the completion inside the
callback, we avoid this problem.

Implement an I/O space index-data register pair as defined by the AHCI
spec, including the corresponding SATA PCI capability and BAR.
This allows real-mode code to access the AHCI registers; real-mode
code cannot address the memory-mapped register space because it is
beyond the first megabyte.

Convert the simple trace backend to glib so that it works under Windows.
We cannot use pthread directly but glib provides portable abstractions.
Also use glib atomics instead of newish gcc builtins which may not be
supported on Windows toolchains.

String arguments are useful for producing human-readable traces without
post-processing (e.g. stderr backend). Although the simple backend
cannot handles strings all others can. Strings should be allowed and
the simple backend can be extended to support them.

If pkg-config doesn't exist then make configure fail immediately
with a useful error message. Now that glib is a required dependency,
proceeding despite the missing pkg-config will just cause us to
fail later with a misleading message about glib not being present.

Work with kvm enabled or disabled. strace output is more readable (less syscalls).

I've found that FreeBSD AHCI driver doesn't work with AHCI hardware
emulation of QEMU 0.15.0. I believe the problem is on QEMU's side. As I
see, it clears port's Interrupt Enable register each time when reset of
any level happens. Is is reasonable for the global controller reset. It
is probably not good, but acceptable for FreeBSD driver for the port
hard reset. But it is IMO wrong for the device soft reset. None of real
hardware I know behaves that way.
