explicitly export C++ allocator overrides
...
This doesn't make any difference for GCC, but these aren't replaced
outside of the library with Clang without explicitly exporting them.

support replacing C++ new/delete implementation
...
This adds support for sanity checks based on sized deallocation and will
reduce the overhead of calls through the C++ allocator.

use a consistent style for fixed-size int types
...
The stdint.h types don't cover 128-bit integers and the underscore makes
them ill suited to usage in function suffixes. Instead, use the common
naming style in the Linux kernel and elsewhere including the ChaCha8
implementation included here.
