As recommended, an `internal/assert` package was added with a reduced set of assertions. All tests were then refactored to use the internal assertions. When more complex assertions were used, they have been rewritten using logic and the simplified assertions.
Fancy formatting for failures was omitted. The `internal/assert/assertions.diff` function could be overwritten for better formatting. That is where diff libraries are used in other test suites.

The test meant to assert that the size of entry does not grow beyond
what it is today. 48 is the current size in bytes on x64. On 32-bit
platform that value should be less. As written the test was doing the
opposite comparison.
