tests+mgmt: Import common unit test code NFD

This commit introduces BaseFixture, UnitTestTimeFixture,
IdentityManagementFixture, and IdentityManagementTimeFixture.
In addition to that, the command line of the unit test binary (for boost
libraries before 1.62) are extended to support multi-format output.

This commit also addresses a strange bug in the management tool that was
causing spurious segmentation faults during unit tests.
