e0f4acc929 Remove workaround for ancient FreeBSD versions before 2.2.8. 
This workaround was unnecessarily active for current DragonFlyBSD,
as well as probably for current FreeBSD as well, because the
"pcvt" console support would be used by default. Hence this adds
explicit code for the PCVT case to skip the quirk on FreeBSD and
DragonFlyBSD.

afc8ec2475 xfree86: add macros for declaring XF86ModuleData fields 
XF86_MODULE_DATA_INPUT() creates XF86ModuleData field for input driver,
while XF86_MODULE_DATA_VIDEO creating one for a video driver.

These are filled with given values, _X_EXPORT'ed and properly named so
the module loader can find them. Also creating the associated
XF86ModuleVersionInfo field and link them into the XF86ModuleData.

Example:

    XF86_MODULE_DATA_INPUT(
        egalax,
        eGalaxPlug,
        eGalaxUnplug,
        "egalax",

dc55d361d8 glamor/glamor_egl.c: Report skipping all modifiers as failure 
If `glamor_get_modifiers` returns no modifiers, but succeeds, it means
that modifiers are implicit and chosen by the driver
(e.g. when allocating gbm buffers)

If we strip all modifiers however, it means that from the list
of modifiers we queried, we can use none.
This means that it would be an error to, for example,
create a gbm bo, create an image from it and try to
render into it.

We should treat this case as a failure.

186e269a9d glamor/glamor_egl.c: Skip modifiers that do not result in images 
that can be rendered to

According to https://registry.khronos.org/EGL/extensions/EXT/EGL_EXT_image_dma_buf_import_modifiers.txt ,
there is an interface that allows us to detect if a given format modifier is supported.

For example, nvidia uses this to report that pitch-linear images can't be
rendered to.

Since we are only interested in formats that we can actually render to,
we should strip these formats from the modifier list.
