cba201f4c7 target/alpha: Remove use_exit_tb
We have not needed to end a TB for I/O since ba3e792669
("icount: clean up cpu_can_io at the entry to the block").
We do not need to use exit_tb for singlestep, which only
means generate one insn per TB.

Which leaves only singlestep_enabled, which means raise a
debug trap after every TB, which does not use exit_tb,
which would leave the function mis-named.

a4390647f7 tcg: Move tb_phys_invalidate_count to tb_ctx
We can call do_tb_phys_invalidate from an iocontext, which has
no per-thread tcg_ctx.  Move this to tb_ctx, which is global.
The actual update still takes place with a lock held, so only
an atomic set is required, not an atomic increment.

834361efd9 tcg: Bake tb_destroy() into tcg_region_tree
The function is called only at tcg_gen_code() when duplicated TBs
are translated by different threads, and when the tcg_region_tree
is reset. Bake it into the underlying GTree as its value destroy
function to unite these situations.
Also remove tcg_region_tree_traverse() which now becomes useless.

1797b08d24 tcg: Avoid including 'trace-tcg.h' in target translate.c
The root trace-events only declares a single TCG event:

  $ git grep -w tcg trace-events
  trace-events:115:# tcg/tcg-op.c
  trace-events:137:vcpu tcg guest_mem_before(TCGv vaddr, uint16_t info) "info=%d", "vaddr=0x%016"PRIx64" info=%d"

and only a tcg/tcg-op.c uses it:

  $ git grep -l trace_guest_mem_before_tcg
  tcg/tcg-op.c

therefore it is pointless to include "trace-tcg.h" in each target
(because it is not used). Remove it.

12a521b56d block: Add backend_defaults property
backend_defaults property allow users to control if default block
properties should be decided with backend information.

If it is off, any backend information will be discarded, which is
suitable if you plan to perform live migration to a different disk backend.

If it is on, a block device may utilize backend information more
aggressively.

By default, it is auto, which uses backend information for block
sizes and ignores the others, which is consistent with the older
versions.

7ca6f2ad37 config-host.mak: remove unused compiler-related lines
Most of the build is not done via Makefiles, therefore the toolchain
variables are mostly unused.  They are still used by tests/tcg
and pc-bios/roms, but most of them are not needed there.

3983a767e3 Set icon for QEMU binary on Mac OS
Before switching the build system over to Meson, an icon was
added to the QEMU binary on Mac OS. This patch adds back that
feature; it piggybacks on the existing scripts/entitlement.sh,
which already does in-place changes to the executable on Darwin.

fe68090e8f machine: add smp compound property
Make -smp syntactic sugar for a compound property "-machine
smp.{cores,threads,cpu,...}".  machine_smp_parse is replaced by the
setter for the property.

numa-test will now cover the new syntax, while other tests
still use -smp.

d8fb7d0969 vl: switch -M parsing to keyval
Switch from QemuOpts to keyval.  This enables the introduction
of non-scalar machine properties, and JSON syntax in the future.

For JSON syntax to be supported right now, we would have to
consider what would happen if string-based dictionaries (produced by
-M key=val) were to be merged with strongly-typed dictionaries
(produced by -M {'key': 123}).

The simplest way out is to never enter the situation, and only allow one
-M option when JSON syntax is in use.  However, we want options such as
-smp to become syntactic sugar for -M, and this is a problem; as soon
as -smp becomes a shortcut for -M, QEMU would forbid using -M '{....}'
together with -smp.  Therefore, allowing JSON syntax right now for -M
would be a forward-compatibility nightmare and it would be impossible
anyway to introduce -M incrementally in tools.

Instead, support for JSON syntax is delayed until after the main
options are converted to QOM compound properties.  These include -boot,
-acpitable, -smbios, -m, -semihosting-config, -rtc and -fw_cfg.  Once JSON
syntax is introduced, these options will _also_ be forbidden together
with -M '{...}'.

9176e800db keyval: introduce keyval_merge
This patch introduces a function that merges two keyval-produced
(or keyval-like) QDicts.  It can be used to emulate the behavior of
.merge_lists = true QemuOpts groups, merging -readconfig sections and
command-line options in a single QDict, and also to implement -set.
