pcie: enable Extended tag field support

SBSA ACS has test 824 which checks for PCIe device capabilities. BSA

softmmu: Support concurrent bounce buffers

When DMA memory can't be directly accessed, as is the case when
running the device model in a separate process without shareable DMA
file descriptors, bounce buffering is used.

It is not uncommon for device models to request mapping of several DMA
regions at the same time. Examples include:
* net devices, e.g. when transmitting a packet that is split across
several TX descriptors (observed with igb)
* USB host controllers, when handling a packet with multiple data TRBs
(observed with xhci)

Previously, qemu only provided a single bounce buffer per AddressSpace
and would fail DMA map requests while the buffer was already in use. In
turn, this would cause DMA failures that ultimately manifest as hardware
errors from the guest perspective.

This change allocates DMA bounce buffers dynamically instead of
supporting only a single buffer. Thus, multiple DMA mappings work
correctly also when RAM can't be mmap()-ed.

The total bounce buffer allocation size is limited individually for each
AddressSpace. The default limit is 4096 bytes, matching the previous
maximum buffer size. A new x-max-bounce-buffer-size parameter is
provided to configure the limit for PCI devices.

pci: don't skip function 0 occupancy verification for devfn auto assign

When the devfn is already assigned in the command line, the
do_pci_register_device() may verify if the function 0 is already occupied.

However, when devfn < 0, the verification is skipped because it is part of
the last "else if".

For instance, suppose there is already a device at addr=00.00 of a port.

-device pcie-root-port,bus=pcie.0,chassis=115,id=port01,addr=0e.00 \
-device virtio-net-pci,bus=port01,id=vnet01,addr=00.00 \

When 'addr' is specified for the 2nd device, the hotplug is denied.

(qemu) device_add virtio-net-pci,bus=port01,id=vnet02,addr=01.00
Error: PCI: slot 0 function 0 already occupied by virtio-net-pci, new func virtio-net-pci cannot be exposed to guest.

When 'addr' is automatically assigned, the hotplug is not denied. This is
because the verification is skipped.

(qemu) device_add virtio-net-pci,bus=port01,id=vnet02
warning: PCI: slot 1 is not valid for virtio-net-pci, parent device only allows plugging into slot 0.

Fix the issue by moving the verification into an independent 'if'
statement.

pcie_sriov: Allow user to create SR-IOV device

A user can create a SR-IOV device by specifying the PF with the
sriov-pf property of the VFs. The VFs must be added before the PF.

A user-creatable VF must have PCIDeviceClass::sriov_vf_user_creatable
set. Such a VF cannot refer to the PF because it is created before the
PF.

A PF that user-creatable VFs can be attached calls
pcie_sriov_pf_init_from_user_created_vfs() during realization and
pcie_sriov_pf_exit() when exiting.

hw/pci: Fix SR-IOV VF number calculation

pci_config_get_bar_addr() had a division by vf_stride. vf_stride needs
to be non-zero when there are multiple VFs, but the specification does
not prohibit to make it zero when there is only one VF.

Do not perform the division for the first VF to avoid division by zero.

hw/pci: Replace -1 with UINT32_MAX for romsize

romsize is an uint32_t variable. Specifying -1 as an uint32_t value is
obscure way to denote UINT32_MAX.

Worse, if int is wider than 32-bit, it will change the behavior of a
construct like the following:
romsize = -1;
if (romsize != -1) {
...
}

When -1 is assigned to romsize, -1 will be implicitly casted into
uint32_t, resulting in UINT32_MAX. On contrary, when evaluating
romsize != -1, romsize will be casted into int, and it will be a
comparison of UINT32_MAX and -1, and result in false.

Replace -1 with UINT32_MAX for statements involving the variable to
clarify the intent and prevent potential breakage.
