[PATCH v2 00/19] hw/i386/pc: Remove deprecated 2.4 and 2.5 PC machines

[Philippe Mathieu-Daudé]

Since v1:
- Fixed issues noticed by Thomas

The versioned 'pc' and 'q35' machines up to 2.12 been marked
as deprecated two releases ago, and are older than 6 years,
so according to our support policy we can remove them.

This series only includes the 2.4 and 2.5 machines removal,
as it is a big enough number of LoC removed. Rest will
follow. Highlight is the legacy fw_cfg API removal :)

These machines has been supported for a period of more than 6 years.
According to our versioned machine support policy (see commit
ce80c4fa6ff "docs: document special exception for machine type
deprecation & removal") they can now be removed.

Remove it and simplify pc_memory_init().

lets remove all the code around VIRTIO_PCI_FLAG_MIGRATE_EXTRA.

[PATCH v2 09/19] hw/i386/pc: Remove deprecated pc-q35-2.5 and pc-i440fx-2.5 machines

[Philippe Mathieu-Daudé]

These machines has been supported for a period of more than 6 years.
According to our versioned machine support policy (see commit
ce80c4fa6ff "docs: document special exception for machine type
deprecation & removal") they can now be removed.

Remove the now unused empty pc_compat_2_5[] array.

There is one more occurance of "pc-i440fx-2.4" in 
tests/qtest/test-x86-cpuid-compat.c which could get removed now, too. But 
this can also be done in a separate patch later, this patch series here 
should now be good to go, I think.
