Only panic if there are disks which would actually be connected to it beyond
its limit. Also skip past disks which are set to NULL. This is useful since
it lets you set up disks on different ports of the controller instead of
filling them contiguously.

The error message says an IDE controller can support at most 4 disks, but the
check would fail if there were more than 3 disks.

Add a case for the ATA command ATAPI_IDENTIFY_DEVICE.
This avoids the panic: Unsupported ATA command when booting a recent Linux
kernel. This was tested on 4.8.13.

We want to extend the stats of objects hierarchically and thus it is necessary
to register the statistics of the base-class(es), as well. For now, these are
empty, but generic stats will be added there.
Patch originally provided by Akash Bagdia at ARM Ltd.

Once again, clang is having issues with recently committed code.
Unfortunately HSAIL_X86 is still broken.

This changeset adds support for notifying the disk images that the simulator has
been forked. We need to disable the saving of the CoW disk image from the child
process, and we need to make sure that systems which use a raw disk image are
not allowed to fork to avoid two or more gem5 processes writing to the same disk
image.
