Please, note that the RunState type as defined in sysemu.h and its
runstate_as_string() function are being dropped in favor of the
RunState type generated by the QAPI.

Next commit will convert the query-status command to use the
RunState type as generated by the QAPI.
In order to "transparently" replace the current enum by the QAPI
one, we have to make some changes to some enum values.
As the changes are simple renames, I'll do them in one shot. The
changes are:
- Rename the prefix from RSTATE_ to RUN_STATE_
- RUN_STATE_SAVEVM to RUN_STATE_SAVE_VM
- RUN_STATE_IN_MIGRATE to RUN_STATE_INMIGRATE
- RUN_STATE_PANICKED to RUN_STATE_INTERNAL_ERROR
- RUN_STATE_POST_MIGRATE to RUN_STATE_POSTMIGRATE
- RUN_STATE_PRE_LAUNCH to RUN_STATE_PRELAUNCH
- RUN_STATE_PRE_MIGRATE to RUN_STATE_PREMIGRATE
- RUN_STATE_RESTORE to RUN_STATE_RESTORE_VM
- RUN_STATE_PRE_MIGRATE to RUN_STATE_FINISH_MIGRATE

The QAPI framework won't generate it, so we need to get rid of it.
In order to do that, this commit makes RSTATE_PRE_LAUNCH the initial
state and change qemu_vmstop_requested() to use RSTATE_MAX.

Otherwise if we have something like 'foo-bar' in the schema,
it will be generated as 'foo_bar' in the string lookup table.
c_var() is good for C variables, but not for enum strings.

Modify logic such that we never assign values to the list head argument
to progress through the list on subsequent iterations, instead rely only
on having our return value passed back in as an argument on the next
call. Also update QMP I/O visitors and test cases accordingly, and add a
missing test case for QmpOutputVisitor.

Previously our logic for keeping track of when we're visiting the head
of a list was done via a global bool. This can be overwritten if dealing
with nested lists, so use stack entries to track this instead.

Currently we do 3 things wrong:
1) The list iterator, in practice, is used in a manner where the pointer
we pass in is the same as the pointer we assign the output to from
visit_next_list(). This causes an infinite loop where we keep freeing
the same structures.
2) We attempt to free list->value rather than list. visit_type_<type>
handles this. We should only be concerned with the containing list.
3) We free prematurely: iterator function will continue accessing values
we've already freed.
This patch should fix all of these issues. QmpOutputVisitor also suffers
from 1).

To get the ball rolling merging QAPI, this patch introduces a "middle mode" to
the code generator. In middle mode, the code generator generates marshalling
functions that are compatible with the current QMP server. We absolutely need
to replace the current QMP server in order to support proper asynchronous
commands but using a middle mode provides a middle-ground that lets us start
converting commands in tree.
Note that all of the commands have been converted already in my glib branch.
Middle mode only exists until we finish merging them from my branch into the
main tree.

This provides a bridge between Error (new error mechanism) and QError (old error
mechanism). Errors can be propagated whereas QError cannot.
The minor evilness avoids layering violations. Since QError should go away RSN,
it seems like a reasonable hack.

The alarm is a fully general one-shot time comparator, which will be
usable under Linux as a hrtimer source. It's much more flexible than
the RTC source available on real hardware.
The wall clock allows the guest access to the host timekeeping. Much
like the KVM wall clock source for other guests.
Both are accessed via the PALcode Cserve entry point.

This is a DP264 variant, SMP capable, no unusual hardware present.
The emulation does not currently include any PCI IOMMU code.
Hopefully the generic support for that can be merged to HEAD soon.
