Prepare for moving the tests to meson. For now they only have
enabled/disabled as the possible values when meson is invoked,
but "auto" will be a possibility later, when configure will only
parse the command line options.

All our supported build platforms have Python 3.6 or newer nowadays, and
there are some useful features in Python 3.6 which are not available in

type the QAPI parser), so let's bump the minimum Python version to 3.6 now.

Now that the installation is relocatable, there is no need to compile a
Windows-format prefix into Win32 binaries. Instead, the prefix will
only be used to compute installation-relative paths, and it can be
any string.
Drop the "Program Files" path completely: it is only usable on English
versions of Windows; therefore, using the NSIS installer to get the
"correct" path to the Program Files folder is recommended, and NSIS
works just as well with any prefix.

not propagate dependencies correctly from static libraries, for example.

Attempting to add the library dependencies at the same time as the

In case the qemu-keymap tool generating them is neither installed on the

qemu will not find the keymaps when started directly from the build

This happens because commit ddcf607fa3 ("meson: drop keymaps symlink")
removed the symlink to the source tree, and the special handling for
install doesn't help in case we do not install qemu.

When using --enable-werror for the macOS builders in the Cirrus-CI,
the atomic64 test is currently failing, and config.log shows a bunch
of error messages like this:
config-temp/qemu-conf.c:6:7: error: implicit declaration of function
'__atomic_load_8' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
y = __atomic_load_8(&x, 0);
^
config-temp/qemu-conf.c:6:7: error: this function declaration is not a
prototype [-Werror,-Wstrict-prototypes]
Seems like these __atomic_*_8 functions are available in one of the
libraries there, so that the test links and passes there when not
using --enable-werror. But there does not seem to be a valid prototype
for them in any of the header files, so that the test fails when using
--enable-werror.
Fix it by using the "official" built-in functions instead (see e.g.
https://gcc.gnu.org/onlinedocs/gcc/_005f_005fatomic-Builtins.html).
We are not using the *_8 variants in QEMU anyway.

This patch implements functionality of following ioctls:
BTRFS_IOC_SUBVOL_CREATE - Creating a btrfs subvolume
Create a btrfs subvolume. The subvolume is created using the ioctl's
third argument which represents a pointer to a following structure
type:
struct btrfs_ioctl_vol_args {
__s64 fd;
char name[BTRFS_PATH_NAME_MAX + 1];
};
Before calling this ioctl, the fields of this structure should be filled
with aproppriate values. The fd field represents the file descriptor
value of the subvolume and the name field represents the subvolume
path.
BTRFS_IOC_SUBVOL_GETFLAGS - Getting subvolume flags
Read the flags of the btrfs subvolume. The flags are read using
the ioctl's third argument that is a pointer of __u64 (unsigned long).
The third argument represents a bit mask that can be composed of following
values:
BTRFS_SUBVOL_RDONLY (1ULL << 1)
BTRFS_SUBVOL_QGROUP_INHERIT (1ULL << 2)
BTRFS_DEVICE_SPEC_BY_ID (1ULL << 3)
BTRFS_SUBVOL_SPEC_BY_ID (1ULL << 4)
BTRFS_IOC_SUBVOL_SETFLAGS - Setting subvolume flags
Set the flags of the btrfs subvolume. The flags are set using the
ioctl's third argument that is a pointer of __u64 (unsigned long).
The third argument represents a bit mask that can be composed of same
values as in the case of previous ioctl (BTRFS_IOC_SUBVOL_GETFLAGS).
BTRFS_IOC_SUBVOL_GETINFO - Getting subvolume information
Read information about the subvolume. The subvolume information is
returned in the ioctl's third argument which represents a pointer to
a following structure type:
struct btrfs_ioctl_get_subvol_info_args {
/* Id of this subvolume */
__u64 treeid;
/* Name of this subvolume, used to get the real name at mount point */
char name[BTRFS_VOL_NAME_MAX + 1];
/*
* Id of the subvolume which contains this subvolume.
* Zero for top-level subvolume or a deleted subvolume.
*/
__u64 parent_id;
/*
* Inode number of the directory which contains this subvolume.
* Zero for top-level subvolume or a deleted subvolume
*/
__u64 dirid;
/* Latest transaction id of this subvolume */
__u64 generation;
/* Flags of this subvolume */
__u64 flags;

All of the fields of this structure are filled after the ioctl call.
Implementation notes:
Ioctls BTRFS_IOC_SUBVOL_CREATE and BTRFS_IOC_SUBVOL_GETINFO have structure
types as third arguments. That is the reason why a corresponding definition
are added in file 'linux-user/syscall_types.h'.
The line '#include <linux/btrfs.h>' is added in file 'linux-user/syscall.c' to
recognise preprocessor definitions for these ioctls. Since the file "linux/btrfs.h"
was added in the kernel version 3.9, it is enwrapped in an #ifdef statement
with parameter CONFIG_BTRFS which is defined in 'configure' if the
header file is present.

Left out in commit 22a87800e6 ("configure: expand path variables for
meson configure", 2020-08-21), do it now.

When cross-compiling, by default qemu_mandir is 'c:\Program
Files\QEMU', which is not recognized as being an absolute path, and
meson will end up adding the prefix again.
Use the pre-prefixed meson mandir option instead.
