When running in thumb mode, Linux doesn't evaluate the immediate value
of the svc instruction, but instead just always assumes the syscall number
to be in r7.

This fixes executing go_bootstrap while building go for me.

Roll the code used to initialize the guest memory space when -R
or -B is used into 'init_guest_space' and then call 'init_guest_space'
from the driver.  This way the reserved guest memory space can
be probed for.  Calling 'mmap' just once as is currently done is not
guaranteed to succeed since the host address space validation might fail.

asprintf is not available for all hosts. g_strdup_printf is
more portable and simplifies the code because if does not
need error handling.

This command attempts to map to the behavior of -cpu ?.  Unfortunately, the
output of this command differs wildly across targets.

To accommodate this, we use a weak symbol to implement a default version of the
command that fails with a QERR_NOT_SUPPORTED error code.  Targets can then
override and implement this command if it makes sense for them.

Emitted when the guest makes a request to enter S4 state.

There are three possible ways of having this event, as described here:

 http://lists.gnu.org/archive/html/qemu-devel/2012-07/msg02307.html

I've decided to add a new event and make it indepedent of SHUTDOWN.
This means that the SHUTDOWN event will eventually follow the
SUSPEND_DISK event.

I've choosen this way because of two reasons:

 1. Having an indepedent event makes it possible to query for its
    existence by using query-events

 2. In the future, we may allow the user to change what QEMU should
    do as a result of the guest entering S4. So it's a good idea to
    keep both events separated
