Reformat and Cleanup of all .xs and .t files

This is huge ... Best to do it before git history builds up.
I have removed all TABS ... A space is always a space!
Indenting is TWO spaces.
I have removed most of the fix comments, I will annotate them in history later.
There have been no code changes other then formatting, no code error fixes, no bug fixes ... I have noted many and will patch them shortly.
I probably should of done this with 1.63 then add 1.42_1 and 1.42_2 as patches!
Maybe I'll still do that ... :)
