Prevously, if we hotplug a device(e.g. device_add e1000) during
migration is processing in source side, qemu will add a new ram
block but migration_bitmap is not extended.
In this case, migration_bitmap will overflow and lead qemu abort
unexpectedly.

We need the names of RAMBlocks as they're loaded for RDMA,
reuse a slightly modified ram_control_load_hook:
a) Pass a 'data' parameter to use for the name in the block-reg
case
b) Only some hook types now require the presence of a hook function.

There are two places that define 'len' variable, It's OK for compiling,
but makes it difficult for reading.
Remove the local one which defined in the inside 'while' loop.

To make changes easier, with the copy, I maintained almost all include
files. Now I remove the unnecessary ones on this patch. This compiles
on linux x64 with all architectures configured, and cross-compiles for
windows 32 and 64 bits.

For historic reasons, ram migration have been on arch_init.c. Just
split it into migration/ram.c, the same that happened with block.c.
There is only code movement, no changes altogether.
