4f1a7ca5a0 displayid: Add support for Type II Detailed Timing Data Block

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.

Also lets the caller set the level of indentation.

8aa57fbed9 edid: turn range limits max pixel clock into an int64_t 
An int32_t is not large enough:
MAX_UINT8 * 10 * 1000 * 1000 > MAX_INT32.

We already use int64_t for di_cta_video_format.pixel_clock.

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.

lines, but not if that degrades readability and is only a few
characters over the limit.
