Reorganize option rom (+linux kernel) loading.
This patch adds infrastructure to maintain memory regions which must be
restored on reset. That includes roms (vga bios and option roms on pc),
but is also used when loading linux kernels directly. Features:
- loading files is supported.
- passing blobs is supported.
- target address range is supported (for optionrom area).
- fixed target memory address is supported (linux kernel).
New in v2:
- writes to ROM are done only at initial boot.
- also handle aout and uimage loaders.
- drop unused fread_targphys() function.
The final memory layout is created once all memory regions are
registered. The option roms get addresses assigned and the
registered regions are checked against overlaps. Finally all data
is copyed to the guest memory.
Advantages:
(1) Filling memory on initial boot and on reset takes the same
code path, making reset more robust.
(2) The need to keep track of the option rom load address is gone.
(3) Due to (2) option roms can be loaded outside pc_init(). This
allows to move the pxe rom loading into the nic drivers for
example.
Additional bonus: There is a 'info roms' monitor command now.
The patch also switches over pc.c and removes the
option_rom_setup_reset() and load_option_rom() functions.

temporary fix for on_vcpu
Recent changes made on_vcpu hit the abort() path, even with the IO thread
disabled. This is because cpu_single_env is no longer set when we call this
function. Although the correct fix is a little bit more complicated that that,
the recent thread in which I proposed qemu_queue_work (which fixes that, btw),
is likely to go on a quite different direction.
So for the benefit of those using guest debugging, I'm proposing this simple
fix in the interim.

gdbstub: x86: Switch 64/32 bit registers dynamically
Commit
56aebc891674cd2d07b3f64183415697be200084 changed gdbstub in way
that debugging 32 or 16-bit guest code is no longer possible with qemu
for x86_64 guest CPUs. Since that commit, qemu only provides registers
sets for 64-bit, forcing current and foreseeable gdb to also switch its
architecture to 64-bit. And this breaks if the inferior is 32 or 16 bit.
No question, this is a gdb issue. But, as it was confirmed in several
discusssions with gdb people, it is a non-trivial thing to fix. So until
qemu finds a gdb version attach with a rework x86 support, we have to
work around it by switching the register layout as the guest switches
its execution mode between 16/32 and 64 bit.

Enable host-clock-based RTC
Switch RTC emulations to the new host_clock instead of vm_clock by
default. This has the advantage that the emulated RTC will follow
automatically the host time while it might be tuned via NTP. vm_clock
can still be selected by passing '-rtc clock=vm' on the command line.
Note that some RTC emulations (at least M48T59) already use the host
time unconditionally while others (namely MC146818) do not. This patch
introduces the required infrastructure for selecting the base clock but
only converts MC146818 for now.

Introduce QEMU_CLOCK_HOST
Despite its name QEMU_CLOCK_REALTIME is (normally) not using
CLOCK_REALTIME / the host system time as base. In order to allow also
non-trivial RTC emulations (MC146818) to follow the host time instead of
the virtual guest time, introduce the new clock type QEMU_CLOCK_HOST. It
is unconditionally based on CLOCK_REALTIME, thus will follow system time
changes of the host.
The only limitation of its current implementation is that pending
host_clock timers may not fire early if the host time is pushed forward
beyond their expiry. So far no urgent need to overcome this limitation
was identified, so it's left as simple as it is (expiry on next alarm
timer tick).

Fix exit on 'pci_add' Monitor command
If the user issues one of the following commands to the Monitor:
pci_add pci_addr=auto nic model=None
pci_add pci_addr=auto nic model=?
QEMU will exit, because the function used to perform sanity
checks (qemu_check_nic_model_list()) exits on error.
This function is used by the startup code, where it makes
sense to exit on error, but in the Monitor it doesn't.
Changing qemu_check_nic_model_list() to not exit on error
is not possible though, as it's used by the board init
code (the PC one), where all board specific code must have
void return.
The way I've chosen to fix this was to introduce a new function
called pci_nic_supported(), which checks if the NIC is supported
and returns true or false accordingly.
The new function is used only by the Monitor, it performs the
necessary check and returns an error in case the NIC is not
supported, thus qemu_check_nic_model_list()'s exit is never trigged.
The following should be observed:
1. Only the specified NIC is checked, the default one is assumed
to be supported
2. The NIC query command (model=?) won't work with pci_add, the
right way to do this with the Monitor is to add a new command

Correctly free nd structure
When we "free" a NICInfo structure, we can leak pointers, since we don't do
much more than setting used = 0.
We free() the model parameter, but we don't set it to NULL. This means that
a new user of this structure will see garbage in there. It was not noticed
before because reusing a NICInfo is not that common, but it can be, for
users of device pci hotplug.
A user hit it, described at https://bugzilla.redhat.com/show_bug.cgi?id=524022
This patch memset's the whole structure, guaranteeing that anyone reusing it
will see a fresh NICinfo. Also, we free some other strings that are currently
leaking.
This codebase is quite old, so this patch should feed all stable trees.

do proper cpu_self check
Currently, our check for qemu_cpu_self only checks if there is a cpu
currently in execution (represented by cpu_single_env being set). While
this might be okay for tcg, it is certainly not okay for kvm, since multiple
cpus might be executing.
Instead, I propose we use pthread primitives to test if the caller thread is
the same as env->thread.
For tcg, it will have the same semantics as before, since all CPUStates will
point to the same thread, and we'll only have one in execution at a time.

The qdev_gpio conversion of 343ec8e caused come polarity mismatch of key

reality:
- Instantiate all 32 GPIO input pins and do the routing only via
qdev_connect_gpio_out.
- Implement IMR and IER registers. They manage the GPIO pin IRQ. IMR
seems to enable IRQs on rising edges, IER on falling ones. At least
this matches what the Musicpal fireware require.
