perform size checks on memcpy/memmove/memset 
- memset is disabled for now as it causes hangs
- underlying functions were copied from isoalloc, licensed Apache-2.0
	- credit Chris Rohlf for memcpy/memset
	- credit David Carlier for memmove
- use the fast path as some programs crash otherwise

f042a6b9b0 android: add function for disabling MTE at runtime 
On Android, MTE is always enabled in Zygote, and is disabled after fork for apps that didn't opt-in
to MTE.

Depends on the slab canary adjustments in the previous commit.

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
