4716ff5b92 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.

e6e9ac1fc9 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.

dcd969ae04 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.
