[PATCH 1/4] test/extmem: refactor and rename test functions

[Anatoly Burakov <anatoly.burakov@intel.com>]

We will be adding a new extmem test that will behave roughly similar
to already existing, so clarify function names to distinguish between
these tests, as well as factor out the common parts.
