ahci: add port I/O index-data pair

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...

Use new macro QEMU_PACKED for packed structures

Most changes were made using these commands:

git grep -la '__attribute__((packed))'|xargs perl -pi -e 's/__attribute__\(\(packed\)\)/QEMU_PACKED/'
git grep -la '__attribute__ ((packed))'|xargs perl -pi -e 's/__attribute__ \(\(packed\)\)/QEMU_PACKED/'...

block: explicit I/O accounting

Decouple the I/O accounting from bdrv_aio_readv/writev/flush and
make the hardware models call directly into the accounting helpers.

This means:
- we do not count internal requests from image formats in addition
to guest originating I/O...

ahci: make number of ports runtime determined

Different AHCI controllers have a different number of ports, so the core
shouldn't care about the amount of ports available.

This patch makes the number of ports available to the AHCI core runtime
configurable, allowing us to have multiple different AHCI implementations...

ahci: send init d2h fis on fis enable

The drive sends a d2h init fis on initialization. Usually, the guest doesn't
receive fises yet at that point though, so the delivery is deferred.

Let's reflect that by sending the init fis on fis receive enablement....
