We don't need to do this.
Add session_context which stores data shared in each import session.
No more global pstring intern pool, to make orcus filters re-entrant.

Now, each orcus_* class stores string_pool instance, and the document
has its own string pool.
Up the version to 0.7.0 and the API version to 0.8.

pstring's exported symbols have changed due to the removal of static
intern methods.
Add documentation on how xlsx and ods handle column widths and row heights.
Keep it consistent in configure.ac & test files updated.
Add --without-tools configure to skip building of binary tools.
Get liborcus-spreadsheet-model to build when --enable-static.
Disable this.
Fix memory leak.
Have immediate parent context manage the life cycle of its own child contexts.

The top level context handler now only deletes the root xml context instance.
Each individual context class is now responsible for managing the life cycles
of its own child contexts that it returns.

With this, a context can re-use the same instance repeatedly as a child
context instead of creating each child context on the heap.
Fix memory leak in orcus-gnumeric.
Move the context stack handling part up to xml_stream_handler.

It was just a bunch of copy-n-pasted block code blocks.
Re-use the same para_text_context instance, for better efficiency.
Make it a concrete data member.
New test file with custom column widths and row heights applied.
Skeleton implementation for handling automatic styles in ods.
Minor formatting oddity.

Auto-generated from SlickEdit. Apparently the compiler parses it fine...
ORCUS_ header guard prefix.
More on parsing automatic styles context.
