Started working on the hash table module integration, fixed a bug:

- entities.[ch] xpath.[ch] hash.[ch] debugXML.c tree.h: added/hacked
  hash tables from Bjorn Reese <breese@mail1.stofanet.dk>. Switched
  XPath functions and XML entities table to them. More to come...
- xmlIO.c: fixed libxml closing FILEs it didn't open.
