to it with earlier commit "slirp: fork_exec(): create and connect
child socket before fork()".
Factor out socket pair creation, to simplify the fork_exec() code.
Use the name socketpair_with_oob() since the code is actually similar
to what socketpair() would do, except that it uses TCP sockets, for
SLIRP to be able to call send with MSG_OOB (since SO_OOBINLINE is set,
this could probably be faked instead on regular unix sockets though).

qemu/queue.h: reimplement QTAILQ without pointer-to-pointers
QTAILQ is a doubly linked list, with a pointer-to-pointer to the last
element from the head, and the previous element from each node.
But if you squint enough, QTAILQ becomes a combination of a singly-linked
forwards list, and another singly-linked list which goes backwards and
is circular. This is the idea that lets QTAILQ implement reverse
iteration: only, because the backwards list points inside the node,
accessing the previous element needs to go two steps back and one
forwards.
What this patch does is implement it in these terms, without actually
changing the in-memory layout at all. The coexistence of the two lists
is realized by making QTAILQ_HEAD and QTAILQ_ENTRY unions of the forwards
pointer and a generic QTailQLink node. Thq QTailQLink can walk the list in
both directions; the union is needed so that the forwards pointer can
have the correct type, as a sort of poor man's template. While there
are other ways to get the same layout without a union, this one has
the advantage of simpler operation in the debugger, because the fields
tqh_first and tqe_next still exist as before the patch. Those fields are
also used by scripts/qemugdb/mtree.py, so it's a good idea to preserve them.
The advantage of the new representation is that the two-back-one-forward
dance done by backwards accesses can be done all while operating on
QTailQLinks. No casting to the head struct is needed anymore because,
even though the QTailQLink's forward pointer is a void *, we can use
typeof to recover the correct type. This patch only changes the
implementation, not the interface. The next patch will remove the head
struct name from the backwards visit macros.

test: replace gtester with a TAP driver

glib suggests instead using Automake's TAP support, which gtest itself
supports since version 2.38 (QEMU's minimum requirement is 2.40).
We do not support Automake, but we can use Automake's code to beautify
the TAP output. I chose to use the Perl copy rather than the shell/awk
one, with some changes so that it can accept TAP through stdin, in order
to reuse Perl's TAP parsing package. This also avoids duplicating the

scsi: esp: Defer command completion until previous interrupts have been handled
The guest OS reads RSTAT, RSEQ, and RINTR, and expects those registers

esp_command_complete() is called.
The guest OS would then try to handle INTR_BS combined with an old

esp-pci: Fix status register write erase control
Per AM53C974 datasheet, definition of "SCSI Bus and Control (SBAC)"
register:
Bit 24 'STATUS' Write Erase Control
This bit controls the Write Erase feature on bits 3:1 and bit 6 of the DMA
Status Register ((B)+54h). When this bit is programmed to '1', the state
of bits 3:1 are preserved when read. Bits 3:1 are only cleared when a '1'
is written to the corresponding bit location. For example, to clear bit 1,
the value of '0000_0010b' should be written to the register. When the DMA
Status Preserve bit is '0', bits 3:1 are cleared when read.
The status register is currently defined to bit 12, not bit 24.
Also, its implementation is reversed: The status is auto-cleared if
the bit is set to 1, and must be cleared explicitly when the bit is
set to 0. This results in spurious interrupts reported by the Linux
kernel, and in some cases even results in stalled SCSI operations.
Set SBAC_STATUS to bit 24 and reverse the logic to fix the problem.

memory: update coalesced_range on transaction_commit
The e1000 driver calls memory_region_add_coalescing but
kvm_coalesce_mmio_region is never called for those regions. The bug
dates back to the introduction of the memory region API; to fix it,
delete and re-add coalesced MMIO ranges when building the FlatViews.
Because coalesced MMIO regions apply to all address spaces, the
has_coalesced_range flag has to be changed into an int.

Store whether the FlatRange has had any coalesced I/O ranges applied,
and if not avoid calling coalesced_io_del. This is useful in preparation
for the next patch, which will call coalesced_io_del when rendering
memory regions.

memory: extract flat_range_coalesced_io_{del,add}
Extract two new functions from memory_region_update_coalesced_range_as.
To avoid duplication in the creation of the MemoryRegionSection, use
MEMORY_LISTENER_UPDATE_REGION instead of MEMORY_LISTENER_CALL
to invoke the listener callback.

The default is to show them on a tty.

checkpatch: improve handling of multiple patches or files
Similar to how patchew output looks like for multiple patches,
say what file or patch is being tested _before_ emitting errors.
This is clearer to a human that scans the output from top to
bottom.
In addition, provide a truncated commit hash and subject instead of
the full hash, and process the commits first-to-last rather than
last-to-first.

accel: Improve selection of the default accelerator
When compiling with "--disable-tcg", we currently still use "tcg"
as default accelerator. "kvm" should be used in this case instead.
Also, some downstream distros provide QEMU binaries which have "kvm"
in their names (e.g. "qemu-kvm" on RHEL or "kvm" on Ubuntu) that use
KVM by default - and some users might want to do something similar
with upstream binaries, too. Accomodate them by using "kvm:tcg" as
default when we detect such a binary name.

roms: seabios: Rename CROSS_COMPILE to CROSS_PREFIX
SeaBIOS introduced CROSS_PREFIX in 2013 but it's not set in roms
Makefile.
With the change it's possible to cross-compile SeaBIOS on macOS,
if acpica/iasl is installed:
cd roms
export PATH=/path/to/cross/x86_64-unknown-linux-gnu/bin:$PATH
make bios system=unknown-linux-gnu
