[PATCH v2 01/11] t: move reftable/block_test.c to the unit testing framework

[Chandra Pratap <chandrapratap3519@gmail.com>]

reftable/block_test.c exercises the functions defined in
reftable/block.{c, h}. Migrate reftable/block_test.c to the unit
testing framework. Migration involves refactoring the tests
to use the unit testing framework instead of reftable's test
framework and renaming the tests to follow the unit-tests'
naming conventions.
