use calculated size for overflow tests
...
This greatly reduces how much these tests depend on hard-wired knowledge
about the size classes.

fix small allocation canary overwrite test
...
Overwriting one byte of a canary with 0 has a 1/256 chance of not
triggering the expected failure.

Make the testsuite work for read-after-free

This commit makes the testsuite fail if
the read-after-free tests are failing, instead
of simply printing some info.

enable sized deallocation for sized deletion test

Clang doesn't currently enable sized deallocation by default like GCC.

Add a test to prove that hardened_malloc handles too-large-to-be-true allocations
...
This pattern, used by https://github.com/kaist-hacking/HardsHeap ,
uncovered bugs in other memory allocators.

Fix CPPFLAGS in test Makefile
...
In particular, the _GNU_SOURCE feature test macro needs to be set in
order to correctly define mmap(2) flags such as MAP_ANONYMOUS.
Otherwise, compilation of some test files fails when CPPFLAGS is not
defined in the initial user environment, as Make then does not export it
from the root Makefile to the sub-make.

malloc_usable_size: clean abort on invalid region
...
It's the region pointer that can be NULL here, and p was checked at the
beginning of the function. Also fix the test accordingly.

increase size for eight_byte_overflow_large test
...
This was not working as expected due to CONFIG_EXTENDED_SIZE_CLASSES
resulting in 128k being a slab allocation size class. The addition of
padding for the canary pushes it into the next size class, resulting in
this writing over size class rounding padding rather than this actually
being an overflow as intended.
