isa: Use realizefn for ISADevice

Drop ISADeviceClass::init and the resulting no-op initfn and let
children implement their own realizefn. Adapt error handling.
Split off an instance_init where sensible.

block: add block driver read only whitelist

We may want to include a driver in the whitelist for read only tasks
such as diagnosing or exporting guest data (with libguestfs as a good
example). This patch introduces a readonly whitelist option, and for
backward compatibility, the old configure option --block-drv-whitelist...

pc_sysfw: allow flash (-pflash) memory to be used with KVM

When pc-sysfw.rom_only == 0, flash memory will be
usable with kvm. In order to enable flash memory mode,
a pflash device must be created. (For example, by
using the -pflash command line parameter.)...

isapc: Fix non-KVM qemu boot (read/write memory for isapc BIOS)

The isapc machine with seabios currently requires the BIOS region
to be read/write memory rather than read-only memory.

KVM currently cannot support the BIOS as a ROM region, but qemu
in non-KVM mode can. Based on this, isapc machine currently only...

memory: Rename readable flag to romd_mode

"Readable" is a very unfortunate name for this flag because even a
rom_device region will always be readable from the guest POV. What
differs is the mapping, just like the comments had to explain already.
Also, readable could currently be understood as being a generic region...

Revert "pc: Kill the "use flash device for BIOS unless KVM" misfeature"

This reverts commit 9953f8822cc316eec9962f0a2858c3439a80adec.
While Markus's analysis is entirely correct, there are 1.6 patches
that fix the bug for real and without requiring machine type hacks....

m25p80.c: Sync Flash chip list with Linux

Add new devices for various manufacturers, and re-sort Spansion list to
match the order in Linux, which requires chips with a non-zero extended ID
to come first.

With this commit the outstanding differences to Linux rev 55bf75b are:...
