Add checks for removing a region from reserved memory in different
scenarios:
- The requested region matches one in the collection of reserved
memory regions
- The requested region does not exist in memblock.reserved
- The region overlaps with one of the entries: from the top (its
end address is bigger than the base of the existing region) or
from the bottom (its base address is smaller than the end address
of one of the regions)
- The region is within an already defined region

Add checks for removing a region from available memory in different
scenarios:
- The requested region matches one in the collection of available
memory regions
- The requested region does not exist in memblock.memory
- The region overlaps with one of the entries: from the top (its end
address is bigger than the base of the existing region) or from the
bottom (its base address is smaller than the end address of one of
the regions)
- The region is within an already defined region

Add checks for marking a region as reserved in different scenarios:
- The region does not overlap with existing entries
- The region overlaps with one of the previous entries: from the top
(its end address is bigger than the base of the existing region) or
from the bottom (its base address is smaller than the end address of
one of the regions)
- The region is within an already defined region
- The same region is marked as reserved twice

Add checks for adding a new region in different scenarios:
- The region does not overlap with existing entries
- The region overlaps with one of the previous entries: from the top
(its end address is bigger than the base of the existing region) or
from the bottom (its base address is smaller than the end address of
one of the regions)
- The region is within an already defined region
- The same region is added twice to the collection of available memory
regions

structures to expected values.

Memblock simulator needs to be able to reset memblock data structures
between different test cases. Add a function that sets all fields to
their default values.
Add a test checking if memblock is being initialized to expected values.
