user.

Internal container module operates file descriptor to media file. For
this purpose, the structure has fd member and any file operation is done
internally. However, the case to use special file descriptor such as
memfd requires to maintain file descriptor externally.
This commit opens file descriptor outside of container module. The
internal APIs to initialize container get an argument for the file
descriptor instead of file path.

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.
