This patch adds a file transfer interface to fw_cfg. Intended to be
used for passing non-pci option roms and vgabios to seabios. Namespace
is modeled after the existing cbfs filesystem support in seabios.
Reading the new FW_CFG_FILE_DIR entry returns a file list.
Fields there are in network byte order (aka bigendian).
aliguori: fix fw_cfg.h for multiboot.bin, add proper fw_cfg.h declarations,
quiet fprintf() in fw_cfg.c

In the very least, a change like this requires discussion on the list.
The naming convention is goofy and it causes a massive merge problem. Something
like this _must_ be presented on the list first so people can provide input
and cope with it.
This reverts commit 99a0949b72.

Disable the lengthy BIOS prompt for selecting a boot device by default,
but let the user reenable it via '-boot menu=on'.

This reverts commit 8217606e6e (and
updates later added users of qemu_register_reset), we solved the
problem it originally addressed less invasively.

The parameter is always zero except when registering the three internal
io regions (ROM, unassigned, notdirty). Remove the parameter to reduce
the API's power, thus facilitating future change.

Add the parameter 'order' to qemu_register_reset and sort callbacks on
registration. On system reset, callbacks with lower order will be
invoked before those with higher order. Update all existing users to the
standard order 0.
Note: At least for x86, the existing users seem to assume that handlers
are called in their registration order. Therefore, the patch preserves
this property. If someone feels bored, (s)he could try to identify this
dependency and express it properly on callback registration.

My previous commit, f92f8afebe, broke -vnc (spotted by Glauber Costa). This
is because it's necessary to tell when the no special display parameters have
been passed and default to SDL or VNC appropriately.
This refactors the display selection logic to be less complicated which has
the effect of fixing the regression mentioned above.

fw_cfg_add_callback() checks if key has FW_CFG_WRITE_CHANNEL bit set
after masking the key with FW_CFG_ENTRY_MASK.
But as FW_CFG_ENTRY_MASK is ~(FW_CFG_WRITE_CHANNEL | FW_CFG_ARCH_LOCAL),
the bit is never set and function exits.
This patch corrects this by checking the bit before masking the value.
