Chris Kennelly b5e4a225e4 Use sdallocx, if available, when deallocating. 
Providing a size hint to the allocator is substantially faster,
especially as we already know/need the size for OPENSSL_cleanse.

We provide a weak symbol that falls back to free when a malloc with
sdallocx is not statically linked with BoringSSL.

Alternatives considered:
* Use dlsym():  This is prone to fail on statically linked binaries
  without symbols.  Additionally, the extra indirection adds call
  overhead above and beyond the linker resolved technique we're using.
* Use CMake rules to identify whether sdallocx is available:  Once the
  library is built, we may link against a variety of malloc
  implementations (not all of which may have sdallocx), so we need to
  have a fallback when the symbol is unavailable.
