c692079597 decodetree: Suppress redundant declaration warnings
We can tell that a decodetree input file is "secondary" when it
uses an argument set marked "!extern".  This indicates that at
least one of the insn translation functions will have already
been declared by the "primary" input file, but given only the
secondary we cannot tell which.

Avoid redundant declaration warnings by suppressing them with pragmas.

13d4ff07e8 trace: Do not include qom/cpu.h into generated trace.h
docs/devel/tracing.txt explains "since many source files include
trace.h, [the generated trace.h use] a minimum of types and other
header files included to keep the namespace clean and compile times
and dependencies down."

Commit 4815185902 "trace: Add per-vCPU tracing states for events with
the 'vcpu' property" made them all include qom/cpu.h via
control-internal.h.  qom/cpu.h in turn includes about thirty headers.
Ouch.

Per-vCPU tracing is currently not supported in sub-directories'
trace-events.  In other words, qom/cpu.h can only be used in
trace-root.h, not in any trace.h.

Split trace/control-vcpu.h off trace/control.h and
trace/control-internal.h.  Have the generated trace.h include
trace/control.h (which no longer includes qom/cpu.h), and trace-root.h
include trace/control-vcpu.h (which includes it).

The resulting improvement is a bit disappointing: in my "build
everything" tree, some 1100 out of 6600 objects (not counting tests
and objects that don't depend on qemu/osdep.h) depend on a trace.h,
and about 600 of them no longer depend on qom/cpu.h.  But more than
1300 others depend on trace-root.h.  More work is clearly needed.
Left for another day.

988fa10304 trace: Eliminate use of TARGET_FMT_plx
hw/tpm/trace-events uses TARGET_FMT_plx formats with uint64_t
arguments.  That's wrong, TARGET_FMT_plx takes hwaddr.  Since hwaddr
happens to be uint64_t, it works anyway.  Messed up in commit
ec427498da, v2.12.0.  Clean up by replacing TARGET_FMT_plx with its
macro expansion.

scripts/tracetool/format/log_stap.py (commit 62dd1048c0, v4.0.0) has
a special case for TARGET_FMT_plx.  Delete it.

874acb6f83 checkpatch: detect doubly-encoded UTF-8
Copy and pasting from Thunderbird's "view source" window results in double
encoding of multibyte UTF-8 sequences.  The appearance of those sequences is
very peculiar, so detect it and give an error despite the (low) possibility
of false positives.

As the major offender, I am also adding the same check to my applypatch-msg
and commit-msg hooks, but this will also cause patchew to croak loudly when
this mistake happens.

6b7ac49d57 minikconf: do not include variables from MINIKCONF_ARGS in config-all-devices.mak
When minikconf writes config-devices.mak, it includes all variables including
those from MINIKCONF_ARGS.  This causes values from config-host.mak to "stick" to
the ones used in generating config-devices.mak, because config-devices.mak is
included after config-host.mak.  Avoid this by omitting assignments coming
from the command line in the output of minikconf.

157dd36395 qapi: Simplify how QAPIDoc implements its state machine
QAPIDoc uses a state machine to for processing of documentation lines.
Its state is encoded as an enum QAPIDoc._state (well, as enum-like
class actually, thanks to our infatuation with Python 2).

All we ever do with the state is calling the state's function to
process a line of documentation.  The enum values effectively serve as
handles for the functions.

Eliminate the rather wordy indirection: store the function to call in
QAPIDoc._append_line.  Update and improve comments.

03bf06bdc1 qapi: Disentangle QAPIDoc code
Documentation comments follow a certain structure: First, we have a text
with a general description (called QAPIDoc.body). After this,
descriptions of the arguments follow. Finally, we have a part that
contains various named sections.

The code doesn't show this structure, but just checks various attributes
that indicate indirectly which part is being processed, so it happens to
do the right set of things in the right phase. This is hard to follow,
and adding support for documentation of features would be even harder.

This patch restructures the code so that the three parts are clearly
separated. The code becomes a bit longer, but easier to follow. The
resulting output remains unchanged.

6a8c0b5102 qapi: Add feature flags to struct types
Sometimes, the behaviour of QEMU changes without a change in the QMP
syntax (usually by allowing values or operations that previously
resulted in an error). QMP clients may still need to know whether
they can rely on the changed behavior.

Let's add feature flags to the QAPI schema language, so that we can make
such changes visible with schema introspection.

An example for a schema definition using feature flags looks like this:

    { 'struct': 'TestType',
      'data': { 'number': 'int' },
      'features': [ 'allow-negative-numbers' ] }

Introspection information then looks like this:

    { "name": "TestType", "meta-type": "object",
      "members": [
          { "name": "number", "type": "int" } ],
      "features": [ "allow-negative-numbers" ] }

This patch implements feature flags only for struct types. We'll
implement them more widely as needed.

17560e9349 decodetree: Initial support for variable-length ISAs
Assuming that the ISA clearly describes how to determine
the length of the instruction, and the ISA has a reasonable
maximum instruction length, the input to the decoder can be
right-justified in an appropriate insn word.

This is not 100% convenient, as out-of-line %fields are
numbered relative to the maximum instruction length, but
this appears to still be usable.

b33b890cd0 trace: avoid SystemTap dtrace(1) warnings on empty files
target/hppa/trace-events only contains disabled events, resulting in a
trace-dtrace.dtrace file that says "provider qemu {}".  SystemTap's
dtrace(1) tool prints a warning when processing this input file.

This patch avoids the error by emitting an empty file instead of
"provider qemu {}" when there are no enabled trace events.

082c0543ba scripts/make-release: Stop shipping u-boot source as a tarball
In commit d0dead3b6d we changed to shipping the u-boot
sources as a tarball, to work around a problem where they
contained a file and directory that had the same name except
for case, which was preventing QEMU's source tarball being
unpacked on case-insensitive filesystems.

In commit f2a3b549e3 we updated our u-boot blob
and sources to v2019.01, which no longer has this problem,
so we can finally remove our workaround (effectively
reverting d0dead3b6d).
