- Add icl_pdu_append_bio and icl_pdu_get_bio methods.
- Add new page pod routines for allocating and writing page pods for
unmapped bio requests. Use these new routines for setting up DDP
for iSCSI tasks with a SCSI I/O CCB which uses CAM_DATA_BIO.
- When ICL_NOCOPY is used to append data from an unmapped I/O request
to a PDU, construct unmapped mbufs from the relevant pages backing
the struct bio. This also requires changes in the t4_push_pdus path
to support unmapped mbufs.

Don't assume that csio->data_ptr is pointer to a data buffer that can
be passed to icl_get_pdu_data and icl_append_data. For unmapped I/O
requests, csio->data_ptr is instead a pointer to a struct bio as
indicated by CAM_DATA_BIO. To support these requests, add
icl_pdu_append_bio and icl_pdu_get_bio methods which pass a pointer to
the bio and an offset and length relative to the bio's buffer.
Note that only backends supporting unmapped requests need to implement
these hooks.

The associated csio ccb will not be completed via xpt_done() until
after the associated PDUs are transmitted to the other side and either
the original PDU is acked with a SCSI response, or a response is
received for a subsequent abort CCB (which means the earlier PDU has
also been sent since it would have been sent before the abort PDU).
This does assume that once an I/O request has been aborted, no further
PDUs with data payload are queued for that I/O request.

Add a elf_putregnote() helper to build the ELF note for a register
set. Once nice result of this approach is that this reuses the
kernel's support for generating 32-bit register sets for 32-bit
processes avoiding the need to duplicate that logic in elf32core.c.

In particular, use a generic wrapper around struct regset rather than
requiring per-regset helpers. This helper replaces the MI
__elfN(note_prstatus) and __elfN(note_fpregset) helpers. It also
removes the need to explicitly dump NT_ARM_ADDR_MASK in the arm64
__elfN(dump_thread).

- Refine the checks for ARM mapping symbols and apply them on arm64 as
well as 32-bit arm. In particular, mapping symbols can have
additional characters and are not strictly limited to just "$a" but
can append additional characters (e.g. "$a.1"). Add "$x" to the
list of mapping symbol prefixes.
- Clear the LSB of function symbol addresses. Thumb function
addresses set the LSB to enable Thumb mode. However, the actual
function starts at the aligned address with LSB clear. Not clearing
the LSB can cause pmcannotate to pass misaligned addresses to
objdump when extracting disassembly.

Some PCI devices especially GPUs require a ROM to work properly.
The ROM is executed by boot firmware to initialize the device.
To add a ROM to a device use the new ROM option for passthru device
(e.g. -s passthru,0/2/0,rom=<path>/<to>/<rom>).
It's necessary that the ROM is executed by the boot firmware.
It won't be executed by any OS.
Additionally, the boot firmware should be configured to execute the
ROM file.
For that reason, it's only possible to use a ROM when using
OVMF with enabled bus enumeration.

In order to support various types of data stored in device
tree properties or ACPI _DSD packages, create a new enum so
the caller can specify the expected type of a property they
want to read, according to the binding. The bus logic will use
that information to process the underlying data.
For example in DT all integer properties are stored in BE format.
In order to get constant results across different platforms we
need to convert its endianness to match the host.
Another example are ACPI_TYPE_INTEGER properties stored
as uint64_t. Before this patch the ACPI logic would refuse
to read them if the provided buffer was smaller than 8 bytes.
Now this can be handled by using DEVICE_PROP_UINT32 type.
Modify the existing consumers of this API to reflect the changes
and update the man pages accordingly.
