Currently FdMigrationState doesn't support read(), and this patch
introduces it to get response from the other side. Note that this
won't change the existing migration protocol to be bi-directional.

Hi,
During live migration, if the receiver side of qemu gets killed, the
sender side seems to be handling the error incorrectly, like it passes
the iterate phase (stage 2) and moves on to the complete state (stage
3). These patches fix the issue.
Yoshiaki Tamura (2):
savevm: avoid
returning 1/0, and avoids
migrate_fd_put_ready() to proceed in case of error.

Although migrate_fd_put_buffer() sets MIG_STATE_ERROR if it failed,
since migrate_fd_put_notify() isn't checking error of underlying
QEMUFile, those resources are kept open. This patch checks it and
calls migrate_fd_error() in case of error.
