Takashi Sakamoto b878df1ff0 axfer: add unit test for container interface
In former commits, container module gets supports of parser/builder for
several types of file format. This commit adds a unit test for them.
This includes positive test cases only. The test cases actually generate
I/O to file systems for many test cases. It takes a long time to finish.
