13a1f578cb use calculated size for overflow tests 
This greatly reduces how much these tests depend on hard-wired knowledge
about the size classes.

acda766e2c 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.

ffdf7b1ee1 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.

de7a3b6e5a enable sized deallocation for sized deletion test 
Clang doesn't currently enable sized deallocation by default like GCC.

cff1d6d4b5 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.

a33d2ca97d 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.

76860c72e1 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.

d757835d90 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.
