* Makefile.am: add streaming on memory regression tests, found
  bad bugs in the reader interface
* xmlreader.c: fixing bugs w.r.t. very large names, and special
  condition in end of file.
* xmlIO.c tree.c include/libxml/tree.h include/libxml/xmlIO.h:
  adding immutable buffers, and parser input based on those,
  but this should not be used (yet) for general parsing
* parser.c: added a comment about using immutable buffers for
  general parsing.
* result/bigname.xml.rdr result/bigname2.xml.rdr: fixing the
  output of the regression tests
* xmllint.c: using the immutable buffers when streaming on
  mmaped file (--stream --memory)

* SAX2.c include/libxml/parser.h: starting work on reusing the
  parser dictionary for the element and attribute tag names.
  Add pools for Element and Attributes in the parser context,
  which should help speeding up the reader.
* Makefile.am result/*.rdr : adding non-python reader regression
  tests.
