The Meson build system is integrated in the existing configure/make steps
by invoking Meson from the configure script and converting Meson's build.ninja
rules to an included Makefile.
build.ninja already provides tags/ctags/cscope rules, so they are removed.

Meson requires the build dir to be separate from the source tree. Many
people are used to just running "./configure && make" though and the
meson conversion breaks that.
This introduces some backcompat support to make it appear as if an
"in source tree" build is being done, but with the results in the
"build/" directory. This allows "./configure && make" to work as it
did historically, albeit with the output binaries staying under build/.

With Makefiles that have automatically generated dependencies, you
generated includes are set as dependencies of the Makefile, so that they
are built before everything else and they are available when first
building the .c files.
Alternatively you can use a fine-grained dependency, e.g.
target/arm/translate.o: target/arm/decode-neon-shared.inc.c
With Meson you have only one choice and it is a third option, namely
"build at the beginning of the corresponding target"; the way you
express it is to list the includes in the sources of that target.
The problem is that Meson decides if something is a source vs. a
generated include by looking at the extension: '.c', '.cc', '.m', '.C'
are sources, while everything else is considered an include---including
'.inc.c'.
Use '.c.inc' to avoid this, as it is consistent with our other convention
of using '.rst.inc' for included reStructuredText files. The editorconfig
file is adjusted.
Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
Meson doesn't enjoy the same flexibility we have with Make in choosing
the include path. In particular the tracing headers are using
$(build_root)/$(<D).
In order to keep the include directives unchanged,
the simplest solution is to generate headers with patterns like
"trace/trace-audio.h" and place forwarding headers in the source tree
such that for example "audio/trace.h" includes "trace/trace-audio.h".
This patch is too ugly to be applied to the Makefiles now. It's only
a way to separate the changes to the tracing header files from the
Meson rewrite of the tracing logic.

aio_notify() does not set ctx->notified when called with
ctx->aio_notify_me disabled. Therefore aio_notify_me needs to be enabled
during polling.
This is suboptimal since expensive event_notifier_set(&ctx->notifier)
and event_notifier_test_and_clear(&ctx->notifier) calls are required
when ctx->aio_notify_me is enabled.
Change aio_notify() so that aio->notified is always set, regardless of
ctx->aio_notify_me. This will make polling cheaper since
ctx->aio_notify_me can remain disabled. Move the
event_notifier_test_and_clear() to the fd handler function (which is now
no longer an empty function so "dummy" has been dropped from its name).
The next patch takes advantage of this by optimizing polling in
util/aio-posix.c.

When a coprocessor instruction in an AArch32 guest traps to AArch32
Hyp mode, the syndrome register (HSR) includes Rt and Rt2 fields
which are simply copies of the Rt and Rt2 fields from the trapped
instruction. However, if the instruction is trapped from AArch32 to
an AArch64 higher exception level, the Rt and Rt2 fields in the
syndrome register (ESR_ELx) must be the AArch64 view of the register.
This makes a difference if the AArch32 guest was in a mode other than
User or System and it was using r13 or r14, or if it was in FIQ mode
and using r8-r14.
We don't know at translate time which AArch32 CPU mode we are in, so
we leave the values we generate in our prototype syndrome register
value at translate time as the raw Rt/Rt2 from the instruction, and
instead correct them to the AArch64 view when we find we need to take
an exception from AArch32 to AArch64 with one of these syndrome
values.
