largefiles: add tests for summary/outgoing improved in subsequent patches

This patch adds tests for summary/outgoing improved in subsequent
patches, to reduce amount of diffs in each patches.

This patch adds new revisions below:

  - revision  #2 adds new largefiles, but they contain as same data as
    one already existing

    this causes that multiple standins refer the same data entity

  - revision  #3,  #4 and  #5 change the already existing largefile

    this causes that multiple data entities are outgoing for the standin.
     #5 can be used to check de-duplication of "(hash, filename)" pair.

 This file contains testcases that tend to be related to special cases or less
 common commands affecting largefile.

 to boost performance, largefiles checks whether specified patterns are
 related to largefiles in working directory (NOT to STANDIN) or not.
