Migration issues in qemu.git

 I'm hitting some migration issues merging qemu.git into qemu-kvm.git:

1. Crash in mig_cancel test:

(gdb) bt
#0  0x0000003a91c83dbb in memcpy () from /lib64/libc.so.6
#1 0x000000000049c2ff in qemu_get_buffer (f=0x302d870, buf=<value optimized out>, size1=4096) at /usr/include/bits/string3.h:52 #2 0x0000000000409464 in ram_load (f=0x302d870, opaque=<value optimized out>, version_id=4) at /build/home/tlv/akivity/qemu-kvm/arch_init.c:407
#3  0x000000000049cb4c in qemu_loadvm_state (f=0x302d870) at savevm.c:1708
#4 0x0000000000494169 in process_incoming_migration (f=<value optimized out>) at migration.c:63 #5 0x0000000000494517 in tcp_accept_incoming_migration (opaque=<value optimized out>) at migration-tcp.c:163 #6 0x000000000041b67e in main_loop_wait (nonblocking=<value optimized out>) at /build/home/tlv/akivity/qemu-kvm/vl.c:1300 #7 0x00000000004314e7 in kvm_main_loop () at /build/home/tlv/akivity/qemu-kvm/qemu-kvm.c:1710 #8 0x000000000041c67f in main_loop (argc=<value optimized out>, argv=<value optimized out>, envp=<value optimized out>)
    at /build/home/tlv/akivity/qemu-kvm/vl.c:1340
#9 main (argc=<value optimized out>, argv=<value optimized out>, envp=<value optimized out>) at /build/home/tlv/akivity/qemu-kvm/vl.c:3069

This is on the incoming side so the test completes successfully, only leaving a core dump to fill my disks.

2. Intermittent migration failures

Likely suspect is the IDE migration fixes. A merge of the commit just before these changes passes the test, I'm now testing the commit immediately after the changes.
