bedd81f1b6 displayid: Handle Type II timings in di_displayid_type_i_ii_vii_timing 
Type II timings are exactly the same as Type I except more tightly
packed and no information on the aspect ratio. As such, they fit neatly
into the Type I and Type VII structure.

63b483cd46 cta: Pull out speaker allocation struct 
The speaker allocation format is reused in multiple CTA data blocks.
This commit pulls it into its own struct so it can be embedded into
other data block structs.

5142866ee7 cta: be more lenient about data block parsing 
If the data block sizes start overlapping the DTD we cannot continue
parsing this or further data blocks but the ones we parsed already
should be valid.

Similarily if we fail parsing a specific data block the previous ones
should still be valid and the next ones might be as well.

6f7dc0bcf7 Add safety assertions when inserting into array 
Make sure we didn't mess up the array size. Abort instead of
corrupting memory.

Found the array insert operations via:

    git grep '++]'

44e1810f2b edid: split the detailed timing signal union into separate structs 
Nested structs makes it impossible to extend the nested struct after
extending the base struct. The union acts as a single struct in this
case but the nesting is still an issue. Use pointers to those structs instead
to keep all of them extensible. Only the struct which is applicable for the
signal type is not a null pointer to make sure only valid data is accessed.
