Define a new variable LD_JOBS, that can be used to select
the maximum number of linking jobs to be executed in parallel.
If the variable is not defined, maintain the default given by
make -j
Currently, make parallelism at build time is based on the number
of cpus available.
This doesn't work well with LTO at linking, because with LTO the
linker has to load in memory all the intermediate object files
for optimization.
The end result is that, if the gitlab runner happens to run two
linking processes at the same time, the job will fail with an
out-of-memory error,
This patch leverages the ability to maintain high parallelism at
compile time, but limit the number of linkers executed in parallel.

Some error messages contain ambiguous representations of the 'node-name'
parameter. This can be particularly confusing when exchanging QMP
messages (C = client, S = server):
C: {"execute": "block_resize", "arguments": { "device": "my_file", "size": 26843545600 }}
S: {"error": {"class": "GenericError", "desc": "Cannot find device=my_file nor node_name="}}
^^^^^^^^^
This error message suggests one could send a message with a key called
'node_name':
C: {"execute": "block_resize", "arguments": { "node_name": "my_file", "size": 26843545600 }}
^^^^^^^^^
but using the underscore is actually incorrect, the parameter should be
'node-name':
S: {"error": {"class": "GenericError", "desc": "Parameter 'node_name' is unexpected"}}
This behavior was uncovered in bz1651437, but I ended up going down a
rabbit hole looking for other areas where this miscommunication might
occur and changing those accordingly as well.

World-writeable directories have security issues. Avoid showing them in
the documentation since someone might accidentally use them in
situations where they are insecure.
There tend to be 3 security problems:
1. Denial of service. An adversary may be able to create the file
beforehand, consume all space/inodes, etc to sabotage us.
2. Impersonation. An adversary may be able to create a listen socket and
accept incoming connections that were meant for us.
3. Unauthenticated client access. An adversary may be able to connect to
us if we did not set the uid/gid and permissions correctly.
These can be prevented or mitigated with private /tmp, carefully setting
the umask, etc but that requires special action and does not apply to
all situations. Just avoid using /tmp in examples.

Let's report a better error message using error_get_pretty(job->job.err).
If an error object was not set, strerror(-job->ret) is used as fallback,
as explained in include/qemu/job.h:
typedef struct Job {
...
/**
* Error object for a failed job.
* If job->ret is nonzero and an error object was not set, it will be set
* to strerror(-job->ret) during job_completed.
*/
Error *err;

Without any of HEAD^ or HEAD^^ applied, qemu will most likely crash on
the qemu-io invocation, for a variety of immediate reasons. The
underlying problem is generally a use-after-free access into
backup-top's BlockCopyState.
With only HEAD^ applied, qemu-io will run into an EIO (which is not
capture by the output, but you can see that the qemu-io invocation will
be accepted (i.e., qemu-io will run) in contrast to the reference
output, where the node name cannot be found), and qemu will then crash
in query-named-block-nodes: bdrv_get_allocated_file_size() detects
backup-top to be a filter and passes the request through to its child.
However, after bdrv_backup_top_drop(), that child is NULL, so the
recursive call crashes.
With HEAD^^ applied, this test should pass.

When the backup-top node transitions from active to inactive in
bdrv_backup_top_drop(), the BlockCopyState is freed and the filtered
child is removed, so the node effectively becomes unusable.
However, noone told its I/O functions this, so they will happily
continue accessing bs->backing and s->bcs. Prevent that by aborting
early when s->active is false.
(After the preceding patch, the node should be gone after
bdrv_backup_top_drop(), so this should largely be a theoretical problem.
But still, better to be safe than sorry, and also I think it just makes
sense to check s->active in the I/O functions.)

The block job holds a reference to the backup-top node (because it is
passed as the main job BDS to block_job_create()). Therefore,
bdrv_backup_top_drop() cannot delete the backup-top node (replacing it
by its child does not affect the job parent, because that has
.stay_at_node set). That is a problem, because all of its I/O functions
assume the BlockCopyState (s->bcs) to be valid and that it has a
filtered child; but after bdrv_backup_top_drop(), neither of those
things are true.
It does not make sense to add new parents to backup-top after
backup_clean(), so we should detach it from the job before
bdrv_backup_top_drop(). Because there is no function to do that for a
single node, just detach all of the job's nodes -- the job does not do
anything past backup_clean() anyway.

Update old infocenter.arm.com URLs to the equivalent developer.arm.com
ones (the old URLs should redirect, but we might as well avoid the
redirection notice, and the new URLs are pleasantly shorter).
This commit covers the links to the MPS2 board TRM, the various
Application Notes, the IoTKit and SSE-200 documents.

The AN524 has a PL031 RTC, which we have a model of; provide it
rather than an unimplemented-device stub.

The AN524 has a USB controller (an ISP1763); we don't have a model of
it but we should provide a stub "unimplemented-device" for it. This
is slightly complicated because the USB controller shares a PPC port
with the ethernet controller.
Implement a make_* function which provides creates a container
MemoryRegion with both the ethernet controller and an
unimplemented-device stub for the USB controller.

When the MacOS toolbox ROM transfers data from a target device to an unaligned
memory address, the first/last byte of a 16-bit transfer needs to be handled
separately. This means that the first byte is preloaded into the FIFO before
the transfer, or the last byte remains in the FIFO after the transfer.
The result of this is that the PDMA routines must be updated so that the FIFO
is loaded/unloaded if the last 16-bit word is used (rather than the last byte)
and any remaining byte from a FIFO wraparound is handled correctly.

The MacOS toolbox ROM uses non-DMA TI commands to handle the first/last byte

The bottom 5 bits contain the number of bytes remaining in the FIFO which is
trivial to implement with Fifo8 (the remaining bits are unimplemented and left
as 0 for now).

Rename ESP_CMDBUF_SZ to ESP_CMDFIFO_SZ and cmdbuf_cdb_offset to cmdfifo_cdb_offset
to indicate that the command buffer type has changed from an array to a Fifo8.
This also enables us to remove the ESPState field cmdlen since the command length
is now simply the number of elements used in cmdfifo.
