[PATCH 5/5] videomode: rename fields

Structs videomode and display_timing have rather long field names for
the timing values. Nothing wrong with that as such, but this patch
changes them to abbreviations for the following reasons:
* The timing values often need to be used in calculations, and long
field names makes their direct use clumsier.
* The current names are a bit of a mishmash: some words are used as
such, some are shortened, and for some only first letter is used. Some
names use underscode, some don't. All this makes it difficult to
remember what the field names are.
* The abbreviations used in this patch are very common, and there
shouldn't be any misunderstanding about their meaning.
