[PATCH v7 0/3] Begin replacing OpenSSL with CommonCrypto

This is a re-roll of David Aguilar's patch series which eliminates some of the OpenSSL deprecation warnings on Mac OS X.

Patch 1 is new. It extracts the CommonCrypto-related Makefile boilerplate, from his SHA-1-related patch, into a distinct introductory patch which can then be referenced by subsequent patches.

Patch 2, SHA-1 warning elimination, is effectively unchanged.

Patch 3, HMAC warning elimination, no longer abuses COMMON_DIGEST_FOR_OPENSSL, which is an implementation detail of patch 2. Instead, it checks for NO_APPLE_COMMON_CRYPTO introduced in patch 1.

David Aguilar (3):
  Makefile: add support for Apple CommonCrypto facility
  cache.h: eliminate SHA-1 deprecation warnings on Mac OS X
  imap-send: eliminate HMAC deprecation warnings on Mac OS X
