> This patch completes memory management for the C implementation.
> * All schema and datum objects are now freed when dereferenced
> * Four new methods have been added {{avro_wrapstring}}, {{avro_wrapbytes}},
> {{avro_givestring}}, and {{avro_givebytes}}. These new methods allow C
> developers to explicitly state if they want {{libavro}} to copy bytes/string
> (the default), "wrap" them with no memory management or "give" them to
> {{libavro}} to manage. This allows for less buffer copying when decoding
> data.
> * Issues with type punning have been resolved to prevent compiler warnings
> * The {{map}} and {{record}} data structures now implement management
> correctly.
> * A new valgrind test is added and runs during {{make check}} if valgrind is
> found on the build system.
> A future optimization will be to have a stack of allocated objects for each
> obj type instead of always using malloc() and free().
