499cf1027f Rename pci_create_noinit() to pci_create()
It's qdev_create() specialized for PCI, so name it accordingly.

07caea315a Fix pci_add nic not to exit on bad model
Monitor command "pci_add ADDR nic model=MODEL" uses pci_nic_init() to
create the NIC.  When MODEL is unknown or "?", this prints to stderr
and terminates the program.

Change pci_nic_init() not to treat "?" specially, and to return NULL
on failure.  Switch uses during startup to new convenience wrapper
pci_nic_init_nofail(), which behaves just like pci_nic_init() used to
do.

Bonus bug fix: we now check for qdev_init() failing there.

9ee05825d9 Make it obvious that pci_nic_init() can't fail
Before this patch, pci_nic_init() returns NULL when it can't find the
model in pci_nic_models[].  Except this can't happen, because
qemu_check_nic_model_list() just searched for model in
pci_nic_models[], and terminated the program on failure.

Repeating the search here is pointless.  Instead, change
qemu_check_nic_model_list() to return the model's array index.

49bd1458da Fix pci_add storage not to exit on bad first argument
Monitor command "pci_add ADDR storage ..." does its work in
qemu_pci_hot_add_nic().  It called pci_create(..., ADDR) to create the
device.  That's wrong, because pci_create() terminates the program
when ADDR is invalid.

Use pci_get_bus_devfn() and pci_create_noinit() instead.

The idea of using assert() for input validation is rather questionable.

Changes:
  * drive_uninit() wants a DriveInfo now.
  * drive_uninit() also calls bdrv_delete(),
    so callers don't need to do that.
  * drive_uninit() calls are moved over to the ->exit()
    callbacks, destroy_bdrvs() is zapped.
  * setting bdrv->private is not needed any more as the
    only user (destroy_bdrvs) is gone.
  * usb-storage needs no drive_uninit, scsi-disk will

6875204c78 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.

0148fde54c 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
