Add and use functions and macros for printing verbose testing output.
If the Memblock simulator was compiled with VERBOSE=1:
- prefix_push(): appends the given string to a prefix string that will be
printed in test_fail() and test_pass*().
- prefix_pop(): removes the last prefix from the prefix string.
- prefix_reset(): clears the prefix string.
- test_fail(): prints a message after a test fails containing the test
number of the failing test and the prefix.
- test_pass(): prints a message after a test passes containing its test
number and the prefix.
- test_print(): prints the given formatted output string.
- test_pass_pop(): runs test_pass() followed by prefix_pop().
- PREFIX_PUSH(): runs prefix_push(__func__).
If the Memblock simulator was not compiled with VERBOSE=1, these
functions/macros do nothing.
Add the assert wrapper macros ASSERT_EQ(), ASSERT_NE(), and ASSERT_LT().
If the assert condition fails, these macros call test_fail() before
executing assert().

Add checks for memblock_alloc for bottom up allocation direction.
The tested scenarios are:
- Region can be allocated on the first fit (with and without
region merging)
- Region can be allocated on the second fit (with and without
region merging)
Add test case wrappers to test both directions in the same context.

Add checks for memblock_alloc for top down allocation direction.
The tested scenarios are:
- Region can be allocated on the first fit (with and without
region merging)
- Region can be allocated on the second fit (with and without
region merging)
Add checks for both allocation directions:
- Region can be allocated between two already existing entries
- Limited memory available
- All memory is reserved
- No available memory registered with memblock
