Makefile: add support for Apple CommonCrypto facility

As of Mac OS X 10.7, Apple deprecated all OpenSSL functions due to
OpenSSL ABI instability, thus leading to build warnings.  As a
replacement, Apple encourages developers to migrate to its own (stable)
CommonCrypto facility.

Introduce boilerplate which controls whether Apple's CommonCrypto
facility is employed (enabled by default).  Also add a
NO_APPLE_COMMON_CRYPTO build flag with which the user can opt out to
use OpenSSL instead.

[es: extracted CommonCrypto-related Makefile boilerplate into separate
introductory patch]
