Second draft of the Y2038 design document

[Albert ARIBAUD]

Hi all, and a happy New Year while we're still in January.

I have produced a second draft of what will eventually become the Y2038
design document:

https://sourceware.org/glibc/wiki/Y2038ProofnessDesign?rev=55

Hopefully, all comments from previous round have been taken 
Questions, notes, comments, corrections can be appended to the document
and/or discussed here.

Cordialement,
