It's been deprecated since QEMU v3.1. We've explicitly asked in the
deprecation message that people should speak up on qemu-devel in case
they are still actively using the bluetooth part of QEMU, but nobody
ever replied that they are really still using it.
I've tried it on my own to use this bluetooth subsystem for one of my
guests, but I was also not able to get it running anymore: When I was
trying to pass-through a real bluetooth device, either the guest did
not see the device at all, or the guest crashed.
Even worse for the emulated device: When running
qemu-system-x86_64 -bt device:keyboard
QEMU crashes once you hit a key.
So it seems like the bluetooth stack is not only neglected, it is
completely bitrotten, as far as I can tell. The only attention that
this code got during the past years were some CVEs that have been
spotted there. So this code is a burden for the developers, without
any real benefit anymore. Time to remove it.
Note: hw/bt/Kconfig only gets cleared but not removed here yet.
Otherwise there is a problem with the *-softmmu/config-devices.mak.d
dependency files - they still contain a reference to this file which
gets evaluated first on some build hosts, before the file gets
properly recreated. To avoid breaking these builders, we still need
the file around for some time. It will get removed in a couple of
weeks instead.

crypto: improve performance of ciphers in XTS mode
Currently QEMU uses its own XTS cipher mode, however, this has
relatively poor performance.
Gcrypt now includes its own XTS cipher which is at least x2 faster than
what we get with QEMU's on Fedora/RHEL hosts. With gcrypt git master, a
further x5-6 speed up is seen.
This is essential for QEMU's LUKS performance to be viable.

Libgcrypt 1.8.0 added support for the XTS mode. Use this because long
term we wish to delete QEMU's XTS impl to avoid carrying private crypto

As an added benefit, using this improves performance from 531 MB/sec to

indirection.
This is even more noticable with the gcrypt builds in Fedora or RHEL-8
which have a non-upstream patch for FIPS mode which does mutex locking.
This is catastrophic for encryption performance with small block sizes,
meaning this patch improves encryption from 240 MB/sec to 670 MB/sec.

The current approach to capture the Python version is fragile, as it
was demonstrated by a very specific build of Python 3 on Fedora 29
that, under non-interactive shells would print multiline version
information.
The (badly) stripped version output would be sent to config-host.mak,
producing bad syntax and rendering the makefiles unusable. Now, the
Python versions is printed by configure, but only a simple (and better
controlled variable) indicating whether the build system is using
Python 2 is kept on config-host.mak.

We make a few sub-directories recursively, in particular
$(TARGET_DIRS).
For goal "all", we do it the nice way: "all" has a prerequisite
subdir-T for each T in $(TARGET_DIRS), and T's recipe runs make
recursively. Behaves nicely with -j and -k.
For other goals such as "clean" and "install", the recipe runs make
recursively in a for loop. Ignores -j and -k.
The next commit will fix that for "clean" and "install". This commit
prepares the ground by renaming the targets we use for "all" to
include the goal for the sub-make. This will permit reusing them for
goals other than "all".
Targets subdir-T for T in $(TARGET_DIRS) run "make all" in T. Rename
to T/all, and declare phony.
Targets romsubdir-R for R in $(ROMS) run "make" in pc-bios/R. Default
goal is "all" for all R. Rename to pc-bios/R/all, and declare phony.
The remainder are renamed just for consistency.
Target subdir-dtc runs "make libbft/libfdt.a" in dtc. Rename to
dtc/all, and declare phony.
Target subdir-capstone runs make $(BUILD_DIR)/capstone/$(LIBCAPSTONE)
in $(SRC_PATH)/capstone. Rename to capstone/all, and declare phony.
Target subdir-slirp runs "make" in $(SRC_PATH)/slirp. Default goal is

The configure script breaks when the qemu source directory is in a path
containing white spaces, in particular the list of targets is not
correctly generated when calling "./configure --help" because of how the
default_target_list variable is built.
In addition to that, *building* qemu from a directory with spaces breaks
some assumptions in the Makefiles, even if the original source path does
not contain spaces like in the case of an out-of-tree build, or when
symlinks are involved.
To avoid these issues, refuse to run the configure script and the
Makefile if there are spaces or colons in the source path or the build
path, taking as inspiration what the kbuild system in linux does.
