ide/core: Remove explicit setting of BM_STATUS_INT

BM_STATUS_INT is automatically set during ide_set_irq(), there's no reason to
set it manually in addition.

There is even one case where the interrupt status bit was set, but no IRQ was
raised. This is when the PRD table was reached but there is more data to...

ahci: Fix non-NCQ accesses for LBA > 16bits

AHCI provides two ways of reading/writing data:

1) NCQ
2) ATA commands with the LBA in the command FIS

In the second code path, we didn't handle any LBAs that were bigger than
16 bits, so whenever a guest that used high LBA numbers wanted to access...

blockdev: Store -drive option media in DriveInfo

DriveInfo is closely tied to -drive, and like -drive, it mixes
information about host and guest part of the block device. Unlike
DriveInfo, BlockDriverState should be about the host part only.

One of the remaining guest bits there is the "type hint". -drive...

ide: Split qdev "ide-drive" into "ide-hd" and "ide-cd"

An "ide-drive" is either a hard disk or a CD-ROM, depending on the
associated BlockDriverState's type hint. Unclean; disk vs. CD belongs
to the guest part, not the host part.

Have separate qdevs "ide-hd" and "ide-cd" to model disk vs. CD in...

ahci: Fix crashes on duplicate BH registration

If ahci_dma_set_inactive is called a while there is still a pending BH
from a previous run, we will crash on the second run of
ahci_check_cmd_bh as it overwrites AHCIDevice::check_bh. Avoid this
broken and redundant duplicate registration....

ide: Turn debug messages into assertions

These printfs aren't really debug messages, but clearly indicate a bug if they
ever become effective. Noone uses DEBUG_IDE, let's re-enable the check
unconditionally and make it an assertion instead of printfs in the device...

ahci: Unbreak bar registration

Fix regression of 667bb59: ahci_init initializes ahci.mem, so we have to
move bar registration after it.

MSI: Robust resource release

msi_init may fail, so we need to check on uninit if the cap was
actually installed. This also avoids that the users need to check.
