[ITA] expat-2.0.1-1

[Warren Young]

Taking over maintainership of this package from Max Bowsher.  Ported 
from g-b-s to cygport and updated from 1.95.8 to 2.0.1, so I'd like at 
least one GTG before I post the RFU message.

Also, we need a ruling on what to do with the existing expat 1.x stuff. 
  It seems there's an ABI difference between the two versions, which is 
why the DLL package is called libexpat1 instead of libexpat0.  Clearly 
we have to keep libexpat0 for those packages that require it, but do we 
also have to keep the other two packages?

I ask all this because I haven't set any curr: or prev: tags in the 
setup.hint files.  If we do it like I'm thinking, they're not needed, 
because there's only one package that has to be in two versions, and 
they have different package names.
