7a9f8d8d6b Use struct initializers instead of memset() 
This is a bit more type-safe.

e449c1dec8 wlr_drm_format_set_copy: Do not allocate heap 
Address Sanitizer reported two memory leaks because of
fmt not being freed in wlr_drm_format_set_copy.

This commit fixes the memory leak by removing the
allocation to the heap. The struct is allocated to the
stack anyway.

5adb1be3a7 drm_format_set_intersect: Require initialized dst and remove assert 
The usages in linux_dmabuf zero out the dst before passing it so this
change should be fine.

7201aae3d6 render/drm-format-set: add wlr_drm_format_set_intersect 
This intersects two DRM format sets. This is useful for implementing
DMA-BUF feedback in compositors, see e.g. the Sway PR [1].

98f2efde98 render/drm_format_set: remove special LINEAR case 
This was used to make the intersection of INVALID and LINEAR result
in LINEAR. We can now just require LINEAR to be in both lists.

b5d4bc3c62 Improve wlr_drm_format documentation 
A wlroots user can easily get confused and think that `cap` refers to
wlroots buffer capabilities, not array capacity.

c4635c68d2 render/drm_format_set: add special case for LINEAR-only formats 
Our wlr_format_set structs don't hold GBM usage flags. Instead, users
who want to get a LINEAR buffer can use the DRM_FORMAT_MOD_LINEAR
modifier even if the kernel driver doesn't support modifiers.

Add a special case to wlr_drm_format_intersect to properly handle this
situation.

render/drm_format_set: allocate using cap when duplicating 
In wlr_drm_format_dup, allocate the new wlr_drm_format using cap instead
of len. This makes it so the cap field is up-to-date and the chunk of
memory isn't too small if we append new modifiers (we don't allow this
yet but might in the future).

82443ea46b render/drm_format_set: introduce wlr_drm_format_intersect 
Intersects modifiers from two wlr_drm_format structs. If either format
doesn't support modifiers, the resulting format won't support modifiers.

01d4506253 render/drm_format_set: disallow DRM_FORMAT_INVALID 
It doesn't make sense to add DRM_FORMAT_INVALID to a format set. Adding
an assertion allows us to safely query the format set with
DRM_FORMAT_INVALID. See [1].

render: introduce wlr_drm_format_set 
This types adds a container for formats + modifiers.

A list that is of [format [modifier]] was chosen instead of
[format modifer] because that is how GBM accepts them.
