The existing ADB state machine is designed to work with Linux which has a different
interpretation of the state machine detailed in "Guide to the Macintosh Family
Hardware". In particular the current Linux implementation includes an extra change
to IDLE state when switching the VIA between send and receive modes which does not
occur in MacOS, and omitting this transition causes the current mac_via ADB state
machine to fail.
Rework the ADB state machine accordingly so that it can enumerate and autopoll the
ADB under both Linux and MacOS, including the addition of the new adb_autopoll_block()
and adb_autopoll_unblock() functions.

Commit 84051eb400 "adb: add property to disable direct reg 3 writes" introduced
a workaround for spurious writes to ADB register 3 when MacOS 9 enables
autopoll on the mouse device. Further analysis shows that the problem is that
only a partial request is sent, and since the len parameter is ignored then
stale data from the previous request is used causing the incorrect address
assignment.
Remove the disable-reg3-direct-writes workaround and instead check the length
parameter when the write is attempted, discarding the invalid request.

The device introspect test in qtest emits some warnings with the
the pnv machine types during the "nodefaults" phase:
TEST check-qtest-ppc64: tests/qtest/device-introspect-test
qemu-system-ppc64: warning: machine has no BMC device. Use '-device
ipmi-bmc-sim,id=bmc0 -device isa-ipmi-bt,bmc=bmc0,irq=10' to define
one
qemu-system-ppc64: warning: machine has no BMC device. Use '-device

qemu-system-ppc64: warning: machine has no BMC device. Use '-device
ipmi-bmc-sim,id=bmc0 -device isa-ipmi-bt,bmc=bmc0,irq=10' to define
one
This is expected since the pnv machine doesn't create the internal
BMC simulator fallback when "-nodefaults" is passed on the command
line, but these warnings appear in ci logs and confuse people.
Not having a BMC isn't recommended but it is still a supported
configuration, so a straightforward fix is to just silent this
warning when qtest is enabled.

Prior to this change, the vhost_user_fill_msg_region function filled out
all elements of the VhostUserMemoryRegion struct except the mmap_offset.
This function is often called on uninitialized structs, which are then
copied into VHOST_USER_SET_MEM_TABLE and VHOST_USER_ADD/REM_MEM_REG
messages. In some cases, where the mmap_offset was not needed, it was
left uninitialized, causing QEMU to send the backend uninitialized data,
which Coverity flagged as a series of issues.
This change augments the vhost_user_fill_msg_region API, adding a
mmap_offset paramenter, forcing the caller to initialize mmap_offset.
