78cbb964d4 Add alloc_size and alloc_align attributes
This should help a bit the compiler to emit better diagnostics and to improve
the correctness of `__builtin_object_size`.

See https://clang.llvm.org/docs/AttributeReference.html#alloc-size
and https://clang.llvm.org/docs/AttributeReference.html#alloc-align

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.

c6af50d088 use unsigned for ffzl definition
This makes more sense and avoids clang tidy conversion warnings.

8ae78237ae avoid unnecessarily mixing 32-bit and 64-bit ints
It's ever so slightly faster to stick to stick to 64-bit arithmetic and
it avoids clang tidy being unhappy about the implicit widening.

3f8e9d3184 make MREMAP_MOVE_THRESHOLD into size_t constant
This avoids a clang-tidy warning and is a bit cleaner.

1e526fc36b disable incredibly impractical clang-tidy check
bugprone-easily-swappable-parameters is completely impractical for real
world usage. It's a reasonable thing to consider as part of API design
but it mostly applies to having APIs taking a lot of parameters. It's
unreasonable to disallow APIs simply taking 2 integer parameters even as
a loose guideline.

This commit makes the testsuite fail if
the read-after-free tests are failing, instead

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.

4ccd6f16df always enable C++17
The safe_flag check doesn't work properly for C++ flags with Clang so
this wasn't getting enabled despite the conditional compilation being
removed from the code, leading to breaking Clang builds.
