CMD8 is "Reserved" in Spec v1.10.
Spec v2.00 introduces the SEND_IF_COND command:
6.4.1 Power Up
CMD8 is newly added in the Physical Layer Specification Version
2.00 to support multiple voltage ranges and used to check whether
the card supports supplied voltage. The version 2.00 or later host
shall issue CMD8 and verify voltage before card initialization.
The host that does not support CMD8 shall supply high voltage range.

The initial implementation is based on the Specs v1.10 (see a1bb27b1e9).
However the SCR is anouncing the card being v1.01.
The new chapters added in version 1.10 are:
4.3.10 Switch function command
Switch function command (CMD6) 1 is used to switch or expand
memory card functions. [...]
This is a new feature, introduced in SD physical Layer
Specification Version 1.10. Therefore, cards that are
compatible with earlier versions of the spec do not support
it. The host shall check the "SD_SPEC" field in the SCR
register to recognize what version of the spec the card
complies with before using CMD6. It is mandatory for SD
memory card of Ver1.10 to support CMD6.
4.3.11 High-Speed mode (25MB/sec interface speed)
Though the Rev 1.01 SD memory card supports up to 12.5MB/sec
interface speed, the speed of 25MB/sec is necessary to support
increasing performance needs of the host and because of memory
size which continues to grow.
To achieve 25MB/sec interface speed, clock rate is increased to
50MHz and CLK/CMD/DAT signal timing and circuit conditions are
reconsidered and changed from Physical Layer Specification
Version 1.01.
4.3.12 Command system (This chapter is newly added in version 1.10)
SD commands CMD34-37, CMD50, CMD57 are reserved for SD command
system expansion via the switch command.
[These commands] will be considered as illegal commands (as
defined in revision 1.01 of the SD physical layer specification).
The SWITCH_FUNCTION is implemented since the first commit, a1bb27b1e9.
The 25MB/sec High-Speed mode was already updated in d7ecb86752.
The current implementation does not implements CMD34-37, CMD50 and
CMD57, thus these commands already return ILLEGAL.
With this patch, the SCR register now matches the description of the header:
* SD Memory Card emulation as defined in the "SD Memory Card Physical
* layer specification, Version 1.10."

While we skip the GIC_INTERNAL irqs, we don't change the register offset
accordingly. This will overlap the GICR registers value and leave the
last GIC_INTERNAL irq's registers out of update.
Fix this by skipping the registers banked by GICR.
Also for migration compatibility if the migration source (old version
qemu) doesn't send gicd_no_migration_shift_bug = 1 to destination, then
we shift the data of PPI to get the right data for SPI.

The 9p-local code previously relied on P9_DOTL_AT_REMOVEDIR and AT_REMOVEDIR
having the same numerical value and deferred any errorchecking to the

it is not true in general. 9p-handle did this properly however. Move

Both `stbuf` and `local_ioc_getversion` where unused when
FS_IOC_GETVERSION was not defined, causing a compiler warning.
Reorganize the code to avoid this warning.

If the size returned from llistxattr/lgetxattr is 0, we skipped
the malloc call, leaving xattr.value uninitialized. However, this
value is later passed to `g_free` without any further checks,
causing an error. Fix that by always calling g_malloc unconditionally.
If `size` is 0, it will return NULL, which is safe to pass to g_free.

These functions will need custom implementations on Darwin. Since the
implementation is very similar among all of them, and 9p-util already
has the _nofollow version of fgetxattrat, let's move them all there.

In the review of
9p: Avoid warning if FS_IOC_GETVERSION is not defined
Grep Kurz noted this error path was failing to set errp.
Fix that.

The size to pass to the `connect` call is the size of the entire
`struct sockaddr_un`. Passing anything shorter than this causes errors
on darwin.
