Usually the guest can tell the host to flush data to disk. In some cases we
don't want to flush though, but try to keep everything in cache.

So let's add a new cache value to -drive that allows us to set the cache
policy to most aggressive, disabling flushes. We call this mode "unsafe",
as guest data is not guaranteed to survive host crashes anymore.

This patch also adds a noop function for aio, so we can do nothing in AIO
fashion.

The 'quit' Monitor command (implemented by do_quit()) calls
exit() directly, this is problematic under QMP because QEMU
exits before having a chance to send the ok response.

Clients don't know if QEMU exited because of a problem or
because the 'quit' command has been executed.

This commit fixes that by moving the exit() call to the main
loop, so that do_quit() requests the system to quit, instead
of calling exit() directly.

There are many problems with net_set_boot_mask():

1) It is broken when using the device model instead of "-net nic". Example:
   $ qemu-system-x86_64 -device rtl8139,vlan=0,id=net0,mac=52:54:00:82:41:fd,bus=pci.0,addr=0x4 -net user,vlan=0,name=hostnet0 -vnc 0.0.0.0:0 -boot n
   Cannot boot from non-existent NIC
   $
2) The mask was previously used to set which boot ROMs were supposed to be
   loaded, but this was changed long time ago. Now all ROM images are loaded,
   and SeaBIOS takes care of jumping to the right boot entry point depending on
   the boot settings.
3) Interpretation and validation of the boot parameter letters is done on
   the machine type code. Examples: PC accepts only a,b,c,d,n as valid boot
   device letters. mac99 accepts only a,b,c,d,e,f.

As a side-effect of this change, qemu-kvm won't abort anymore if using "-boot n"
on a machine with no network devices. Checking if the requested boot device is
valid is now a task for the BIOS or the machine-type code.
