[Twg] Updated draft requirements posted to discuss

[David Dillow]

A few small updates, added some text for storage semantics and kernel
patches.  There are number of items marked by [[ ]] pairs that need
expansion.

Chris, I think the "redo llapi and lctl" items came from you -- I don't
know what you had in mind there, so please provide some text, or
redirect me if I misremember the origin.

John, can you explain some of the driving forces behind the 10 billion
files in a directory -- how does one plan to work on such a system; will
it be expected to be POSIX compliant?

Steve/Justin -- while I think the user name mapping was mentioned by
Eric, I seem to recall that you guys are working in this area for the
WAN projects. Can you elaborate some text here?

All: we need to fill out the table quite a bit.
