Without the header being explicitly included, scan-build run on CI
was returning errors for these files, such as:
include the header <stdlib.h> or explicitly provide a declaration
for 'calloc'
The functions in question were calloc, free, etc.

The patch adds new functionality to the test: tracking the areas of
chip memory that were modified (i.e. by erase or write operation),
and then checking those areas were completely covered by verify
operation.
The test operates over the mock chip memory of 16 bytes, so it is
possible to track each byte which was modified, and assert that is
has been verified afterwards.
Adding the test found a bug which is fixed in this commit:
Post-cleanup after processing unaligned region for the case when end
region needs to be extended to align with erase block. Writing was
done correctly, but post-processing of newcontents could cause
one-off offset at the end of the region, which would make
verification appear false-negative (see test cases #16-19).

When flash regions are protected, erase could incorrectly erase regions
which were meant to be protected by requesting the correct size but
using an erase opcode with coarser granularity than desired (for
instance using a 16-byte erase command while attempting to erase only 8
bytes).
This fixes that by exchanging the nesting of the loops over erase blocks
and flash regions.
Old:
- Select erasefns
- Loop over blocks to erase for each selected erasefn
- Loop over programmer flash regions within erase block
- Erase regions (may fail since selected erasefn will be
too big if flash region is smaller than erase block)
New:
- Loop over programmer flash regions within erase block
- Select erasefns within programer flash region
- Loop over blocks to erase for each selected erasefn
- Erase regions
Eraser selection and erasing has also been factored out into a helper
function to manage nesting depth.
TEST=New test cases pass, whereas some of them fail without the changes
to erasure_layout.c

This allows tests to verify that the correct opcode is used when
erasing, which is required to unit-test the fix to issue #525 where in
some situations an incorrect erase opcode will be used.

The test cases from #16 onwards cover the case when layout region is
not aligned with eraseblock region, and therefore either layout start
boundary or end boundary needs to be extended to align with
eraseblock.

The test checks that algorithm for erase functions selection
works and there are no regressions.
Specifically, test contains an array of test cases. Each case
initialises a given initial state of the memory for the mock chip,
and layout regions on the chip, and then performs erase and write
operations.
At the end of operation, test asserts the following:
- the state of mock chip memory is as expected, i.e. properly erased
or written
- erase blocks are invoked in expected order and expected number
of them
- chip operation (erase or write) returned 0.
