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

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.

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.

This brings bfd_boolean to the wonderful world of <stdbool.h>, it is needed
because it defines bdf_boolean as an enum with values true and false,

The qdev_gpio conversion of 343ec8e caused come polarity mismatch of key
event pins and left an overly complex solution behind. Take this chance
and refactor the GPIO input system of the Musicpal, moving it closer to
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.
- Move key pin logic inversion from the GPIO layer to musicpal_key.
