Reading the passwords for encrypted hard disks during early startup is
broken (I guess for quiet a while now):
 - No monitor terminal is ready for input at this point
 - Forcing all mux'ed terminals into monitor mode can confuse other
   users of that channels

To overcome these issues and to lay the ground for a clean decoupling of
monitor terminals, this patch changes the initial password inquiry as
follows:
 - Prevent autostart if there is some encrypted disk
 - Once the user tries to resume the VM, prompt for all missing
   passwords
 - Only resume if all passwords were accepted

If the backing file is encrypted, 'info block' currently does not report
the disk as encrypted. Fix this by using the standard API to check disk
encryption mode. Moreover, switch to a canonical output format.

If a target uses a tiny display (like the MusicPal), the default monitor

Currently, the intermediate input buffer of mux'ed character devices
records data across all sub-devices. This has the side effect that we
easily leak data recorded over one sub-devices to another once we switch
the focus. Avoid data loss and confusion by defining exclusive buffers.

Note: In contrast to the original author's claim, the buffering concept
still breaks down when the fifo of the currently active sub-device is
full. As we cannot accept futher data from this point on without risking
to loose it, we will also miss escape sequences, just like without all
that buffering. In short: There is no reliable escape sequence handling
without infinite buffers or the risk of loosing some data.

Recent changes to the graphical console initialization broke the initial
CHR_EVENT_RESET distribution. The reset BHs generated on char device
initialization are now already consumed during machine init (ide init
... -> qemu_aio_wait -> qemu_bh_poll). Therefore, this patch moves the
initial qemu_chr_reset calls into a separate funtion which is called
after machine init.

Version 2 does as follows:

[1]: Corrects endianness on issues by using native BGR to RGB conversion
[2]: Uses DisplayState accessors for obtaining graphics context information,
     which
[3]: Removes now unused variables, and
[4]: Allows reading of varying color modes (32bit/24/16), and converting to
     native colorspace
[5]: Attempts to keep itself centered on screen (as opposed to bottom right,
     which immediately goes off screen after bios load) on context changes
    (window resizes)

Testing working on i386 (gentoo, Windows 2000) and PPC (debian) guests on PPC
and x86 Macs.

In regards to [4], Windows 2000 displays fine on quick tests, but on the lowest
setting I could test, 16bit color depth at 4bpp, colors are slightly off. I
used gentoo install-x86-minimal-2008.0 in framebuffer mode to test above
setting; the usual grey text is now blue, and Tux appears to be BGR shifted. I
do not know if previous code worked at such a low color setting.

Introduce a growable flag that's set by bdrv_file_open().  Block devices should
never be growable, only files that are being used by block devices.

I went through Fabrice's early comments about the patch that was first applied.
While I disagree with that patch, I also disagree with Fabrice's suggestion.

There's no good reason to do the checks in the block drivers themselves.  It
just increases the possibility that this bug could show up again.  Since we're
calling bdrv_getlength() to determine the length, we're giving the block drivers
a chance to chime in and let us know what range is valid.

Basically, this patch makes the BlockDriver API guarantee that all requests are
within 0..bdrv_getlength() which to me seems like a Good Thing.

What do others think?

A real 970 CPU starts up with HIOR=0xfff00000 and triggers a reset
exception, basically ending up at IP 0xfff001000.

Later on this HIOR has to be set to 0 by the firmware in order to
enable the OS to handle interrupts on its own.

This patch maps HIOR to exec_prefix, which does the same thing
internally in qemu already.

It replaces the previous patch that changed the 970 initialization
constants, as this is the clean solution to the same problem.
