New Revision: 2008

Log:
Completely refactored ResUse/Result hierarchy:
- Instead of deriving Result from ResUse, deriving both from a common
base class, ResultBase. (Result is-not-a ResUse!) Objects of the
base type can't be created: it exists only to hold common data and
functionality.
- Renamed ResUse to UseQueryResult
- Renamed Result to StoreQueryResult
- Renamed ResNSel to SimpleResult
- If MYSQLPP_BACKWARDS_COMPATIBLE_RESULT_TYPES is defined, a new set of
compatibility #defines is activated letting you use the old names for
the classes.
- StoreQueryResult now derives from vector<Row> and populates itself on
construction, then disposes of the underlying C API data structure.
Many benefits: 1) operator[] uses reference semantics instead of value
semantics, and operator-> finally (!) works correctly; 2) dropped
dependency on subscript_iterator; 3) concentrates knowledge of C API
in a much smaller area; 4) 100% compatible with STL idioms now. New
refcounting stuff makes this both possible _and_ efficient.
- Only UseQueryResult keeps a MYSQL_RES internal member now. Nothing
had to change in MySQL++, since we only take advantage of the
conversion of UseQueryResult to MYSQL_RES in the implementation of
stuff like Query::storein().
- A few classes that took ResUse parameters as generic result objects
now take ResultBase parameters. It provides all the outsiders need.
- Added DBDriver::free_result() to wrap mysql_free_result()
- IMPORTANT COMPATIBILITY BREAK: because we used fetch_row() stuff in
Result previously, it was okay to index past the end of the result
set: you'd just get a falsy Row when you did this, just as happens
when doing the same thing in a "use" query. The simple1 and simple2
examples did this, so it's likely that code exists that takes
advantage of this misfeature. In documenting breakages, show the
proper method.
