sysemu/sysemu.h is a rather unfocused dumping ground for stuff related
to the system-emulator. Evidence:
* It's included widely: in my "build everything" tree, changing
sysemu/sysemu.h still triggers a recompile of some 1100 out of 6600
objects (not counting tests and objects that don't depend on
qemu/osdep.h, down from 5400 due to the previous two commits).
* It pulls in more than a dozen additional headers.
Split stuff related to run state management into its own header
sysemu/runstate.h.
Touching sysemu/sysemu.h now recompiles some 850 objects. qemu/uuid.h
also drops from 1100 to 850, and qapi/qapi-types-run-state.h from 4400
to 4200. Touching new sysemu/runstate.h recompiles some 500 objects.
Since I'm touching MAINTAINERS to add sysemu/runstate.h anyway, also
add qemu/main-loop.h.

in the switch-case statement in vl.c and not handled in the OS-specifc

Time to wire up all the call sites that request a shutdown or
reset to use the enum added in the previous patch.
It would have been less churn to keep the common case with no
arguments as meaning guest-triggered, and only modified the
host-triggered code paths, via a wrapper function, but then we'd
still have to audit that I didn't miss any host-triggered spots;
changing the signature forces us to double-check that I correctly
categorized all callers.
Since command line options can change whether a guest reset request
causes an actual reset vs. a shutdown, it's easy to also add the
information to reset requests.

In case of -daemonize, we write non-zero to the daemon
pipe only if pidfile creation failed, so the parent will
report error about pidfile problem. There's no need to
make special case for this, since all other errors are
reported by the child just fine. Let the parent report
error and simplify logic in os_daemonize().
This way, we don't need os_pidfile_error() function, since
it only prints error now, so put the error reporting printf
into the only place where qemu_create_pidfile() is called,
in vl.c.
While at it, fix wrong indentation in os_daemonize().

Paolo Bonzini <pbonzini@redhat.com> confirmed this is safe under Wine:
"1) the underlying Win32 APIs require separate arguments for the
variable and value; 2) even though in the end Wine stores the
environment as name=value
(http://source.winehq.org/source/dlls/ntdll/env.c), it does so in a
single consecutive block of memory, not as a char* array like POSIX
does. While (2) might apply only to Wine, (1) surely applies to Windows
as well."

The function that writes pidfile for win32 uses WriteFileEx which is an
asynchronous IO function. The arguments given to WriteFileEx are allocated on
the stack and one of them is "in out". When the IO operation is actually
executed the calling function has already returned, so the arguments are no
longer allocated or allocated to another frame.

BeOS and Haiku on i386 use long for 32-bit types, including pid_t.
Using %d with pid_t therefore results in a warning.
Unfortunately POSIX:2008 does not define a PRId* string for pid_t.
In some places pid_t was previously casted to long and %ld hardcoded.
The predecessor of this patch added another upcast for the simpletrace
filename but was not applied to date.
Since new uses of pid_t with %d keep creeping in, let's instead define
an OS-dependent format string and use that consistently.
