Move target specific functions and RAM handling to arch_init.c.

Add a flag to QEMUOptions structure to indicate for which
architectures the option is allowed, check the flag
in run time and remove conditional code in option handling.

Now that no target dependencies remain, compile vl.c only once
for all targets.

Instead of testing specially next_cpu in host_alarm_handler, just do
that in qemu_notify_event.  The idea is, if we are not running (or
not yet running) target CPU code, prepare things so that the execution
loop is exited asap; just make that clear.

qemu_notify_event in the non-iothread case is only stopping the current
CPU.  However, if the CPU is idle and the main loop is in the select
call then a call to qemu_event_increment is needed too (as done in
host_alarm_handler).  Since in general one doesn't know whether the CPU
is executing or not, it is a safe bet to always do qemu_event_increment.

Another way to see it: after this patch qemu_event_increment is the
"common part" of qemu_notify_event for both the CONFIG_IOTHREAD and
!CONFIG_IOTHREAD cases, which makes sense.

The timer_alarm_pending variable is related to the alarm timer but not
placed in the struct.  Also, in qemu_mod_timer the wrong flag was being
tested: the timer is rearmed in the alarm timer "bottom half", so the
right flag to test there is the "pending" flag.

Finally, I hoisted the NULL checks from alarm_has_dynticks to
host_alarm_handler.

The code is initializing an unsigned int to UINT_MAX using "-1", so that
the following always-true comparison seems to be always-false at a
first look.  Since alarm timer initializations are never nested, it is
simpler to unconditionally store the result of timeGetDevCaps into
data->period.

We sometimes permit omitting the first option name, for example
-device foo is short for -device driver=foo.  The name to use
("driver" in the example) is passed as argument to qemu_opts_parse().
For each QemuOptsList, we use at most one such name.

Move the name into QemuOptsList, and pass whether to permit the
abbreviation.  This ensures continued consistency, and simplifies the
commit after next in this series.
