A new -i flag is introduced to allow users to pretty-print a JSON
dump. Users can now share JSON dumps, and optionally post-process
them, e.g. this can be used to only print the connectors:

    drm_info -j | jq '. | map_values(. | {driver,device,connectors,encoders:[],crtcs:[],planes:[]})' | drm_info -i

virtio doesn't set a version date, no point in printing zero.
Additionally the version date is deprecated:

Closes: #71

This bus is exclusively used by Tegra devices.  Why this isn’t part of
the platform bus, I do not know.  It has the exact same properties as
the platform bus, so it is pretty much a copy/paste of it, with just
different structs in xf86drm.h.

This has been tested on a Nintendo Switch running Linux 6.0.

This gives a clear error message when the subproject isn't set up,
and avoids printing a warning when it's set up.

I tried using a subproject, but Meson will error out when the
subproject calls meson.override_dependency() because the system
libdrm has been picked already.

The workaround fixes this warning:

    ../meson.build:59: WARNING: include_directories sandbox violation!
    The project is trying to access the directory 'subprojects/libdrm/include/drm' which belongs to a different
    subproject. This is a problem as it hardcodes the relative paths of these two projects.
    This makes it impossible to compile the project in any other directory layout and also
    prevents the subproject from changing its own directory layout.

    Instead of poking directly at the internals the subproject should be executed and
    it should set a variable that the caller can then use. Something like:

    # In subproject
    some_dep = declare_dependency(include_directories: include_directories('include'))

    # In subproject wrap file
    [provide]
    some = some_dep

    # In parent project
    some_dep = dependency('some')
    executable(..., dependencies: [some_dep])

    This warning will become a hard error in a future Meson release.

See mesa/drm!277

"+" doesn't fix the error. Use a single line.

Apparently old Meson has a bug and doesn't parse "/" at end-of-line
properly.

Additionally, using "/" here was a mistake: it drops the left part
when the right part is an absolute path. Use "+" instead.

When PKG_CONFIG_SYSROOT_DIR is set, the pkg-config variable `includedir`
only contains the path inside the sysroot. To find the actual file,
prepend the sysroot (defaults to `/`).

-X POST is the default when -d is used.

Fixes the following error, seen in CI:

    ../modifiers.c: In function 'print_arm_modifier':
    ../modifiers.c:207:3: error: a label can only be part of a statement and a declaration is not a statement

Required for the Meson Python module.

Not pretty, but gets the job done.
