fix sized deallocation check with large sizes
...
The CONFIG_CXX_ALLOCATOR feature enables sanity checks for sized
deallocation and this wasn't updated to handle the introduction of
performing size class rounding for large sizes.

realloc: use copy_size to check for canaries

This avoids unnecessarily copying the canary when doing a realloc from a
small size to a large size. It also avoids trying to copy a non-existent
canary out of a zero-size allocation, which are memory protected.

initialize size class CSPRNGs from init CSPRNG
...
This avoids making a huge number of getrandom system calls during
initialization. The init CSPRNG is unmapped before initialization
finishes and these are still reseeded from the OS. The purpose of the
independent CSPRNGs is simply to avoid the massive performance hit of
synchronization and there's no harm in doing it this way.
Keeping around the init CSPRNG and reseeding from it would defeat the
purpose of reseeding, and it isn't a measurable performance issue since
it can just be tuned to reseed less often.
