Fix conversions from pointer to int and vice versa

Here the int values fds0, sigfd, s, sock and fd are converted
to void pointers which are later converted back to an int value.

These conversions should always use intptr_t instead of unsigned long.

They are needed for environments where sizeof(long) != sizeof(void *)....

migration-tcp: call migrate_fd_error() instead of close() and free().

This patch fixes the following error report. When changing
migration-tcp.c to call migrate_fd_error() instead of close() and
free() by itself, monitor is resumed, and returns allocated mig_state...

migration: Clear fd also in error cases

Not clearing the fd and closing the file makes qemu spin using 100%CPU
after incoming migration error.

Do not use dprintf

dprintf is already claimed by POSIX1, and on at least one system
is implemented as a macro

Don't leak file descriptors

We're leaking file descriptors to child processes. Set FD_CLOEXEC on file
descriptors that don't need to be passed to children to stop this misbehaviour.

live migration: Propagate output monitor to callback handler

In order to allow proper progress reporting to the monitor that
initiated the migration, forward the monitor reference through the
migration layer down to SaveLiveStateHandler.

Block live migration

This patch introduces block migration called during live migration. Block

transfer the whole disk and then transfer all dirty blocks accumulted during
the migration....

fix migration to obey -S

Since migration returns right away, starting the VM right
after calling qemu_start_incoming_migration is wrong even
if -S is not passed. We have to do this after migration
has completed.

honor -S on incoming migration

-S is not honored by qemu on incoming migration. If a domain is migrated
while paused, thus, it will start running on the remote machine; this
is wrong.

Given the trivial patch to fix this, it looks more like a thinko
than anything else, probably dating back to the qemu-kvm merge....

monitor: Decouple terminals (Jan Kiszka)

Currently all registered (and activate) monitor terminals work in
broadcast mode: Everyone sees what someone else types on some other
terminal and what the monitor reports back. This model is broken when
you have a management monitor terminal that is automatically operated...

term_print functions are renamed to monitor_* and all monitor services
