Some legacy users (mostly PC devices) of vmstate_register manage
instance IDs on their own, and that unfortunately in a way that is
incompatible with automatically generated ones. This so far prevents
switching those users to vmstates that are registered by qdev.

To establish a migration path, this patch introduces the concept of
alias IDs. They can be passed to an extended vmstate registration
service, and qdev provides a set service to be used during device init.
find_se will consider the alias in addition to the default ID. We can
then start generating the default ID automatically and writing it on
vmsave, thus converting that format without breaking support for upward
migration.

The user is required specify the highest vmstate version for which the
alias is required. Once this version falls behind the minimum required
for a specific vmstate, an assertion triggers to motivate cleaning up
the obsolete alias.

In linux kernel v2.6.33, sm501 frame buffer driver modified to support
2D graphics engine on sm501 chip.  One example is "fill rectangle" operation.
But current qemu's sm501 emulation doesn't support it.  This results in
graphics console disturbance.

This patch introduces sm501 2D graphics engine emulation and solve this problem.

    Add SM501 2D hardware engine support.

     - Add 2D engine register set read/write handlers.
     - Support 'fill rectangle'. Other operations are left for future work.
     - Update SM501 support status comment.
