Add support for -ctrl-grab to use the right-ctrl button to grab/release
the mouse in SDL.

The multi-button ctrl-alt and ctrl-alt-shift grab buttons present an
accessibility problem to users who cannot press more than one button
at a time.

Converting files using "qemu-img convert" onto logical volumes (or any
block device) you need to use the currently undocumented "host_device"
format.  This patch adds the required documentation to the manpage.

This patch adds infrastructure to maintain memory regions which must be
restored on reset.  That includes roms (vga bios and option roms on pc),
but is also used when loading linux kernels directly.  Features:

  - loading files is supported.
  - passing blobs is supported.
  - target address range is supported (for optionrom area).
  - fixed target memory address is supported (linux kernel).

New in v2:
  - writes to ROM are done only at initial boot.
  - also handle aout and uimage loaders.
  - drop unused fread_targphys() function.

The final memory layout is created once all memory regions are
registered.  The option roms get addresses assigned and the
registered regions are checked against overlaps.  Finally all data
is copyed to the guest memory.

Advantages:

  (1) Filling memory on initial boot and on reset takes the same
      code path, making reset more robust.
  (2) The need to keep track of the option rom load address is gone.
  (3) Due to (2) option roms can be loaded outside pc_init().  This
      allows to move the pxe rom loading into the nic drivers for
      example.

Additional bonus:  There is a 'info roms' monitor command now.

The patch also switches over pc.c and removes the
option_rom_setup_reset() and load_option_rom() functions.

Monitor command "pci_add ADDR nic model=MODEL" uses pci_nic_init() to
create the NIC.  When MODEL is unknown or "?", this prints to stderr
and terminates the program.

Change pci_nic_init() not to treat "?" specially, and to return NULL
on failure.  Switch uses during startup to new convenience wrapper
pci_nic_init_nofail(), which behaves just like pci_nic_init() used to
do.

Bonus bug fix: we now check for qdev_init() failing there.

Before this patch, pci_nic_init() returns NULL when it can't find the
model in pci_nic_models[].  Except this can't happen, because
qemu_check_nic_model_list() just searched for model in
pci_nic_models[], and terminated the program on failure.

Repeating the search here is pointless.  Instead, change
qemu_check_nic_model_list() to return the model's array index.

Monitor command "pci_add ADDR storage ..." does its work in
qemu_pci_hot_add_nic().  It called pci_create(..., ADDR) to create the
device.  That's wrong, because pci_create() terminates the program
when ADDR is invalid.

Use pci_get_bus_devfn() and pci_create_noinit() instead.

This patch increases the maximum qcow2 cluster size to 2 MB. Starting with 128k
clusters, L2 tables span 2 GB or more of virtual disk space, causing 32 bit
truncation and wraparound of signed integers. Therefore some variables need to
use a larger data type.

While being at reviewing data types, change some integers that are used for
array indices to unsigned. In some places they were checked against some upper
limit but not for negative values. This could avoid potential segfaults with
corrupted qcow2 images.
