This is a small batch of fixes from recent reports on migration, the plan
is this is only for 11.2; we don't need to rush on any of them.

RDMA migration has its own small batch.. It'll take slightly longer so I'll
send them separately.

Reviews welcomed.

Peter Xu (5):
  migration: Fix possible overflow in vmstate_handle_alloc()
  migration/multifd: Validate next_packet_size in zlib/zstd recv
  migration/multifd: Replace assert() with error_setg() in recv paths
  migration: Fix rare hang of migration_channel_read_peek()
  migration/ram: Check for RAMBlock size mismatch when parsing
