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.

For Windows portability the simple trace backend must use the 'b' file
open mode.  This prevents the stdio library from mangling 0x0a/0x0d
newline characters.

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.
