The memory freelist maintained by OpenSSL claims to be a performance
optimization for platforms that have a slow malloc/free
implementation. This should not be the case on modern
linux/glibc. Remove the freelist as it poses a potential security
hazard of buffer-reuse that is of "initialized" memory that will not
be caught be tools such as valgrind.

The <opensslfeatures.h> header provides #defines which are normally
declared by OpenSSL when features are disabled.
This way applications are able to detect which features were removed
from BoringSSL and use it as drop-in replacement for OpenSSL.
Inspired by LibreSSL, which provides similar header.
